Titanium tube welders law process characteristics titanium alloy pump

Titanium tube welded using inert gas welding area for the effective protection of TiG welding process. Since

titanium has special physical and sunrui titanium alloy pump chemical properties , and thus there is a big difference in the welding process

and other metals.

Titanium pipe welding must ensure :

Pollution ( a ) weld metal zone is not more than 250 ℃ reactive gas N, 0, H and harmful impurity elements C, Fe, Mn

and the like.

( 2 ) can not form a coarse grain structure .

( 3 ) does not produce a large welding residual stress and deformation. Therefore, the welding process is required

to reserve the construction sequence , in strict accordance with process quality management standards , the

implementation of quality control of the whole process. People , machine , material, method factors are controlled

in a good state to work in a reasonable period, to ensure the quality of welding titanium tube.

Titanium pipe welding using materials, equipment and tools

4.1 titanium pipes and fittings : shall have the manufacturer's factory certification and quality certificates .

After retesting its size, chemical Sunrui aerospace investment casting composition , mechanical properties and availability status should comply with

DIN17850 standards.

Titanium pipe welding material

Titanium tube weld cracks and pores problems titanium alloy pump

Titanium tube weld crack problem

When the possibility of titanium sunrui titanium alloy pump welding, thermal cracking of welded joints is small, it is because few impurities

in titanium and titanium alloys S, P, C , etc. , low melting point of S, P eutectic formed at the grain boundaries

rarely generation, coupled with effective crystallization temperature range narrow, titanium and titanium alloy

solidification when a small amount of shrinkage , weld metal does not produce heat cracks.
When titanium and titanium alloy welding, weld when an oxygen , nitrogen is high , the performance of the weld heat

affected zone or become brittle in the larger weld stress, cold cracking occurs . Characterized by cracks in the

weld called a few hours or even longer delay cracks. The study showed that the hydrogen diffusion welding process is

the main cause of such cracks. Hydrogen in the welding process to a lower temperature by diffusion of the high

temperature heat affected zone deep pool , the area increase the hydrogen content of the precipitates increased so

that the amount of TiH2 , brittle heat affected zone is increased , the other due to volume expansion caused by

precipitation of hydrides greater the stress , plus a hydrogen atom diffusion and aggregation to the high stress

areas of the area, resulting in the formation of cracks . This delay prevents cracks approach is to reduce the

welded joint main source of hydrogen .

Titanium tube weld porosity problems

When titanium pipe welding , porosity is Sunrui titanium coils often encountered a major problem. The root cause of the formation of pores

is affected as a result of hydrogen .
Prevent blowholes process measures are:
1 ) in high purity argon welding , argon gas purity not less than 99.99%
2 ) the elimination of titanium tubes , oil and other oxide on the surface of titanium and titanium tubes eye

organics . Can be cleaned with a chemical and mechanical methods.
3 ) subjected to the bath gas well , control the flow and the flow rate of argon gas , to prevent turbulence ,

impact protection.
4 ) Choose the appropriate welding process parameters, welding specification , increasing the residence time of deep

pools to facilitate the use Sunrui aerospace investment casting of air bubbles escape , which can effectively reduce porosity.

Improve the strength and toughness titanium alloy pump titanium alloy pump

Improve the strength and toughness of titanium carbide process improvement measures

For questions titanium carbide sunrui titanium alloy pump cracks and debris in the welding and use often , according to the previous

experimental results were studied process , improve the strength and toughness of the alloy made ​​to prevent cracks

and debris produce good results , strongly proposed to improve the alloy toughness of process improvement measures

are as follows :

1 ) titanium carbide sintering temperature high manganese steel bonded carbide generally the final sintering

temperature 1420 ℃ more appropriate. Sintering temperature is not too high , the temperature is too high titanium

carbide grains grow faster, and even the loss of the binder phase becomes liquid metal , so that the hard phase

occurs adjacent to gather and grow , forming a fragmentation source . This is the bond of the hard phase grains in

the previous analysis phase between fewer reasons. Of course, the sintering temperature can not be too low,

otherwise it would burn less alloy .

2 ) when the heating rate during sintering temperature of these alloys sintering heating rate should not fast ,

especially in degumming , restore, and liquid phase sintering of three stages , to strictly control the heating rate

and holding time . Because low degumming stage, compacts forming agent to release stress and suppress evaporation

process , if the heating speed, due to the volatile and too late after forming agent liquefied into steam , so that

compacts have burst or micro-cracking Sunrui titanium coils phenomenon ; at 900 ℃ the above reduction stage , to make compact enough time

off the raw material powder (e.g., Mn2Fe intermediate alloy ) of volatiles and oxygen ; entering the liquid-phase

sintering stage , but also to slow down the rate of heating sufficiently to make the alloy compacts technology .

Sintered steel bonded carbide principle is the principle of wetting , wetting sufficiently liquid so that the solid

phase ( hard phase ) , otherwise the liquid metal Fe, Mn , etc. will precipitate at the surface of compacts and even

loss.

3 ) the degree of vacuum in the furnace sunrui titanium alloy casting into the liquid phase sintering , in addition to the aforementioned

sintering temperature and velocity control , but also to control the degree of vacuum sintering furnace , because of

high degree of vacuum of the liquid metal causes a large volatile , resulting in segregation .

Material characteristics of titanium alloys and welding titanium alloy pump

Material characteristics ( a ) titanium : density ( about 4.5g/cm3), high tensile strength (441 ~ 1470MPa), that is

the great strength ratio ( strength / density ) sunrui titanium alloy pump large . In sea water and most acids, alkalis, salts medium all have

excellent corrosion resistance compared .

Weldability (b ) a titanium alloy , having a number of significant features, which are due to the physical and

chemical characteristics of welding titanium is determined .

1 impurity contamination caused by gas embrittlement of welded joints

At room temperature , titanium and titanium alloys are relatively stable. However, in the welding process , the

liquid metal droplet and the pool has a strong absorption effect of hydrogen, oxygen, nitrogen , and in the solid

state , with these gases have a role. With increasing temperature , titanium and titanium alloys absorb hydrogen ,

oxygen, nitrogen capacity also will rise significantly , about 250 ℃ titanium began to absorb hydrogen , began to

absorb oxygen from 400 ℃ , 600 ℃ began Sunrui titanium coils to absorb nitrogen from these after the gas is absorbed directly will cause

embrittlement of welded joint is extremely important factor affecting the quality of welding .

( A ) Effect of hydrogen is

Impurities in the hydrogen gas to affect the mechanical properties of titanium most serious factor. The impact of

changes in hydrogen content in the weld performance the most significant effect on the weld , mainly due to the

increase of the hydrogen bomb with the seam with the amount deposited weld flake or needle TiH2 increased. TiH2 low

intensity , the effect of the sheet-like or needle guard according to HiH2 notch impact properties significantly

reduce aggregate ; weld hydrogen to reduce the amount of change effect of improving the strength and the ductility

is not very significant .

( 2) The effect of oxygen

With the oxygen content of the weld is substantially increase the oxygen content in the argon gas increases linearly

with the increase of the oxygen content of the weld , the weld hardness and tensile strength significantly increased

, and the plasticity is significantly reduced. In order to ensure the performance of welded joints , the welding

process should prevent the weld and HAZ fat oxidation.

( 3 ) the impact of nitrogen
At temperatures above 700 ℃ , plays the role of nitrogen and the titanium , titanium nitride is formed a hard

brittle (TiN) is formed of titanium and nitrogen and the slip degree of lattice distortion caused by solid solution

of the gap , the consequences caused by the same amount of oxygen than more seriously , so nitrogen to improve

industrial pure titanium weld tensile strength , hardness, ductility properties of the weld reduced more significant

than that of oxygen . When the nitrogen content in the weld than 0.13% , the weld due to the brittle and cracks .
( 4 ) the impact of carbon
Carbon is also common in titanium and titanium impurities, experiments showed that when the carbon content of 0.13 %

or less, because deep in the α carbon titanium weld strength limit somewhat improved plasticity some decline, but

not as strong role of oxygen and nitrogen . But when further increase the carbon content of the weld , the weld has

appeared mesh TiC, their number increased with the carbon content and increase the weld plastic sharp decline in the

welding prone to stress cracking . When the carbon content of 0.55% weld , the weld disappearance of almost all the

plastic and the material becomes very brittle . Weld heat treatment can not eliminate this brittleness. Of technical

conditions , the carbon content of the titanium alloy of the base material is not more than 0.1% , the carbon

content of the weld does not exceed the base material carbon content.

2 titanium weld defects and Mechanism .
( 1 ) Color oxide
Around about 250 ℃ titanium begins to absorb hydrogen and oxygen to be absorbed from 400 ℃ , 600 ℃ starts from

the absorption of nitrogen , and the air contains large amounts of nitrogen and oxygen species . Titanium during

welding , argon gas protection layer is formed by welding guns can better protect the weld pool from the harmful

effects of air , which has been solidified in the vicinity of the weld and no high-temperature state near

protection, while the area around the weld titanium tube and in this state is still strong absorption of nitrogen

and oxygen in the air capability . Sunrui aerospace investment casting Gradually increased with the degree of oxidation , and changes in the laws of

titanium weld seam plastic drop colors occur. Silver-white ( no oxidation ) , golden yellow (TiO, slightly oxidized

) , blue (Ti2O3, oxidation slightly serious ) , gray (TiO2, oxidation severe ) .

white smoke - it is hydrolyzed into white sunrui titanium alloy pump titanium dioxide hydrogel . In the military , people took advantage of

titanium tetrachloride, which shares a strange temper, as artificial aerosols. Especially in the ocean , water vapor

and more, a release of titanium tetrachloride, a white smoke as the Great Wall , blocking the enemy's line of sight.

In agriculture, the use of titanium tetrafluoride people to frost .

Titanium oxide basic knowledge - barium titanate

Barium titanate crystals have such characteristics : when it changes shape under pressure , generates electricity, a

power will change shape. Thus , the barium titanate in an ultrasonic people , and it will produce a current pressure

, the size of the current generated by it can detect the strength of the ultrasonic wave . Conversely , a high

frequency current through it , it can generate an ultrasonic wave. Now , almost all of the ultrasonic instrument, to

be used in barium titanate . sunrui sunrui titanium precision casting In addition, there are many uses of barium titanate . For example: railway workers put

it on the tracks below , to measure the pressure when the train passed ; doctors use it made ​​of pulse logger. Barium

titanate to do with underwater detectors, underwater eye is sharp , it is not only able to see the fish , but also

you can see the reef , icebergs and Sunrui aerospace investment casting enemy submarines under the water and so on .

Basic knowledge of titanium oxide titanium alloy pump

Introduction to the basics of titanium oxide - titanium dioxide :

Titanium dioxide is a white powder , sunrui titanium alloy pump is the best white pigment , commonly known as titanium dioxide . Previously,

people mining titanium , the main purpose is to obtain titanium dioxide. Strong adhesion of titanium dioxide , a

chemical change is not easy , is always white . Especially valuable is titanium dioxide toxic . Its high melting

point, is used to make fire-resistant glass , enamel glazes , clay, utensils and other high-temperature experiments

. Titanium dioxide is the most white stuff , one gram of titanium dioxide can put more than 450 cm2 in area than the

white painted white pigment commonly used barium zinc white whiter five times , thus modulating the best white paint

pigment . Titanium dioxide pigment sunrui sunrui titanium precision casting used in the world , more than a year to tens of tons. Titanium dioxide can be

added in a paper , the paper white and opaque effect is 10 times larger than any other substance , therefore , we

should banknote paper and art paper plus titanium dioxide. In addition , in order to lighten the color of the

plastic to make rayon soft gloss, and sometimes also added titanium dioxide. In the rubber industry, titanium

dioxide is also used as a filler Sunrui aerospace investment casting of white rubber.

Titanium is a titanium- based alloy by adding other elements titanium pump

There are two isomeric titanium crystals : Below 882 ℃ for the close-packed hexagonal structure α titanium ,

titanium above 882 ℃ for the body-centered sunrui titanium pump cubic β . Alloying elements according to their effect on the phase

transition temperature can be divided into three categories : ① stable α -phase , improving the phase transition

temperature of the elements of α stabilizing element , aluminum , carbon, oxygen and nitrogen . Which aluminum is

the main alloying elements titanium, improving its strength at room temperature and high temperature alloys , lower

specific gravity, increased elastic Sunrui aerospace investment casting modulus have a significant effect . ② stable β -phase, reducing the element of

the phase transition temperature of β stabilizing element , and can be divided isomorphous and eutectoid two . The

former molybdenum , niobium, vanadium, etc. ; latter chromium, manganese, copper, iron , and silicon. ③ small

element of the phase transition temperature of the neutral elements , zirconium and tin .
Oxygen, nitrogen, carbon and hydrogen are the main impurities of titanium . Oxygen and nitrogen in the α phase has

a greater solubility of the titanium alloy has a significant strengthening effect , but the plastic drop. Typically

provide oxygen and nitrogen content of titanium in the 0.15 to 0.2% and 0.04 % to 0.05% or less , respectively . The

solubility of hydrogen in the α phase is very small , titanium dissolved in excess hydride hydrogen will produce

the alloy brittle. Titanium is usually controlled hydrogen content of 0.015% or less. The hydrogen dissolved in the

titanium is reversible , vacuum annealing can be removed .

Titanium has high strength and density and small, good mechanical properties, good toughness and corrosion

resistance. In addition , poor process performance titanium alloys , machining difficulties in thermal processing ,

and very easy to absorb hydrogen nitrogen carbon and other impurities. There are poor abrasion resistance , complex

production process . Titanium industrial production began in 1948 . Requires the development of the aviation

industry , the titanium industry with an average annual growth rate of about 8% growth. Currently the world's

titanium alloy production reached 40,000 tons , nearly 30 kinds of titanium alloys . Is the most widely used

titanium alloy Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and commercially pure titanium (TA1, TA2 and TA3).

Titanium is mainly used for the production of aircraft engine compressor components , followed by structure rockets,

missiles and high-speed aircraft. Mid-1960s , titanium and its alloys have been in general industrial applications ,

electrodes for electrolysis industry production , power plant condensers , oil refineries and desalination heater

and environmental pollution control devices. Titanium and its alloys have become a corrosion resistant structural

materials. In addition, for the production of hydrogen storage materials and shape memory alloys.

China began in 1956, titanium and titanium alloys research ; mid-1960s and the development of industrial production

of titanium into TB2 alloys.

Titanium is a new and important structural materials used in the aerospace industry , the proportion between the

aluminum and steel , strength and temperature ranged , but has high strength and excellent resistance than seawater

corrosion and ultra- low temperature performance. In 1950 the United States for the first time in the F-84 fighter-

bombers used after the fuselage insulation panels, wind shield , tail cover other non- load-bearing components.

1960s began using parts from titanium alloy fuselage toward the rear of the fuselage , in part, to replace

structural steel bulkheads , beams, rails and other important flap bearing components . The amount of titanium in

military aircraft is increasing rapidly , reaching 20 % to 25% by weight of the aircraft structure . Since the 1970s

, began extensive use of titanium Sunrui Titanium Casting Golf Heads civilian aircraft such as the Boeing 747 aircraft with a capacity of 3640 kg or

more of titanium . Aircraft Mach number of less than 2.5 primarily to replace the titanium steel , to reduce

structural weight . Again , the U.S. SR-71 high-altitude reconnaissance aircraft speed ( Mach 3 at an altitude of

26,212 meters ) , 93% titanium by weight of the aircraft structure , known as " all-titanium " aircraft . When the

weight ratio of aircraft engines, increased from 4-6 to 8-10 , a corresponding outlet temperature from compressor

200 ~ 300 ° C to 500 ~ 600 ° C , the original plate is made of aluminum and the blades of the low pressure

compressor must switch to titanium , or titanium instead of stainless steel plate and high-pressure compressor

blades in order to reduce the structural weight . 1970s, the amount of titanium in the general aviation engines

accounted for 20% to 30% of the total weight of the structure is mainly used in the manufacture of compressor

components such as forged titanium fan, compressor discs and blades, cast titanium compressor casing , intermediate

casing, bearing housing and so on. The main advantage of the spacecraft 's high- strength titanium alloy , corrosion

resistance and low temperature performance to manufacture all kinds of pressure vessels, fuel tanks , fasteners,

instrument straps, architecture and rocket shells. Sputnik , the lunar module , manned spaceship and space shuttles

are also using titanium plates welded .

Materials commonly used glasses titanium pump

Most commonly used glasses plastic and metal materials can be divided into two categories

Titanium material found

Development of titanium materials: a sunrui titanium pump German chemist in 1794 ( two hundred and seven years ago ) discovered this new

metal element and named it titanium titanium. Named by sources from the ancient myth of the West Prince Titan (

Titan ) , because he believes that super-strength titanium and ultra- refractory degree , working with the great

Titan with shine .

Although titanium material in the Second ○ was discovered seven years ago , but due to refining process was not

easy ( titanium is very easy to combine with oxygen ) , scientists have been unable to be refined into useful

substances metals. Until 1938 , the company developed a new way to extract , plus magnesium reduction method, the

red and gold reserves in the ground ore , after chlorination, plus magnesium , restore it and become a sponge

titanium, to nineteen in 2043 , the Sunrui Titanium Casting Golf Heads company began producing a large number of titanium metal products.

Development of titanium frames

Titanium is a metallic chemical element , because the refining process is not easy, and less expensive titanium

material production , it is only used in the early titanium aerospace science , marine science and other high-tech

science and energy development . And daily necessities are to begin in 1965 applied to the titanium material .

The first titanium frame is in九八○年someone invented the " rivet -like titanium frames " titanium welding is a

very difficult material, there is no better way to do early connection handling , use rivets type of way to put it

nailed together. While in 1981 , the plant began outside coated with a layer of nickel titanium material to

facilitate welding. May compete with Sunrui aerospace investment casting the growing manufacturing methods in the new market , the company in 1982

launched the first day of the first pay full titanium metal frames around the world ; 1984 also has factories

launched nickel titanium frames, there is a big price difference.

singular role in human health , cancer, the cancer .
Germanium in the human body functions are manifold. First, because it has the dehydrogenation capacity , enabling

the body to maintain adequate oxygen , thereby safeguarding human health. In humans, the decomposition is carried

out by means of oxygen . Food decomposition process , need to consume oxygen , water and carbon dioxide while .

Without sufficient oxygen , it is possible to make the body to cause disease. The human body can germanium hydrogen

ions out of the body to reduce the demand for oxygen , which is conducive to health. Japanese scientists added

dimethyl germanium oxide polymer in honey become popular health products.

The most attention is organic germanium ( Ge dicarboxyethyl trioxide ) anti-cancer effect. According to the study

and practice has proved that organic germanium with the body's " waste" with the body and the blood vessel wall

excess protein and cancer will be adsorbed , 20 to 30 hours later, with a "waste " of germanium, will automatically

excreted from the body . Cancer patients the blood is hypercoagulable state , slowing blood flow velocity , cancer

easily attached to the vessel wall , invasion and destruction of the vessel wall. Meanwhile, the blood viscosity,

easy to form blood clots, wrapped up the cancer cells , the drug is difficult to work. Since organic germanium has a

role in lowering blood viscosity , which can slow down the effect, have anti-cancer effects .
Pure germanium ( 99.999 %) of the function:

( 1 ) enhance immune function
( 2 ) regulation of blood pressure , blood lipids , blood glucose and other physiological functions.
( 3 ) the role of a wide range of cancer treatment .
( 4 ) with anti- carcinogen effect.
( 5 ) has a variety of disease prevention and health functions.
( 6 ) has significant anti-aging effects.
( 7 ) has a whitening cosmetic effect.
( 8 ) of germanium in metabolism , Sunrui Titanium Casting Golf Heads contains multiple Ge-0 bond , with strong oxidative dehydrogenation capacity.
