Titanium tube weld defect is due to the titanium tube welding, Titanium Pipe due to argon arc welding gun formed by the argon gas maintenance layer can only maintain the welding bath from the harmful effects of air, and has been solidified in the vicinity of the high temperature and the weld There is no protective effect in the vicinity of the area, and in this state of the titanium tube weld and the vicinity of the area is still a strong absorption of nitrogen and oxygen in the air capacity

 

When the titanium tube is welded, Titanium Pipe the stomata is a major problem that is often encountered. The root cause of the formation of pores is due to the effect of hydrogen. To prevent the production of stomatal processes are:

 

1. Select the appropriate welding process parameters, welding specifications, increase the residence time of the deep pool to facilitate the use of bubbles to escape, Titanium Pipe can effectively reduce the pores.

 

2. In the high purity argon under the protection of welding, argon purity should not be less than 99.99%

 

3. Completely remove titanium, Titanium Pipe titanium and titanium tube on the surface of the oxide oil on the surface of oil and other organic matter. Can be cleaned chemically and mechanically.

 

4. The pool of good gas protection, Titanium Pipe control the flow of argon and flow rate, to prevent turbulence, affecting the protective effect. The same time as the above-

 

When the titanium alloy is welded, Titanium Pipe the argon gas protective layer formed by the argon arc welding torch can only protect the weld pool from the harmful effects of air, while the weld and its vicinity near the high temperature state Protective effect, and in this state of the titanium tube weld and its vicinity of the area is still very strong absorption of nitrogen and oxygen in the air capacity. Titanium Pipe With the degree of oxidation gradually increased, titanium alloy weld color changes and weld plasticity of the law. Silver (no oxidation), golden yellow (TiO, slightly oxidized), blue (Ti2O3, slightly oxidized), gray (TiO2, severe oxidation).

 

Titanium alloy welding, welding joints produce hot cracks is unlikely, Titanium Pipe it is because titanium and titanium alloy S, P, C and other impurities are few, from S, P formed low melting point eutectic in the grain boundary very few Generation, coupled with the effective crystallization temperature range is narrow, titanium and titanium alloy solidification when the shrinkage is small, the weld metal does not produce hot cracks.

 

Titanium and titanium alloy tube welding, when the weld oxygen, nitrogen is high, with the temperature rise, titanium and its alloys to absorb hydrogen, oxygen and nitrogen capacity gradually increased. Titanium began to absorb hydrogen from 250 ° C, began to absorb oxygen from 400 ° C, Titanium Pipe began to absorb nitrogen from 600 ° C. As the titanium alloy with O2, N2, H2 affinity is high, the joints containing these gases will make the joints brittle, reduce the impact of titanium alloy welded joints, plasticity and toughness.

 

Titanium alloy containing hydrogen in the heat affected zone will produce delayed cracking. When the weld oxygen, nitrogen is high, the weld or heat affected zone under the influence of the larger welding stress cracks, the crack also belongs to the delayed crack. So the protection of inert gas (or vacuum chamber) is very necessary.

 

Titanium is half the weight of steel, so titanium tubing can be made with slightly larger diameters without a weight penalty. Larger diameter tubing provides greater stiffness to efficiently transfer power to the rear wheel without undue flex, all without beating you up over the course of a long ride. It's a magical combination of efficiency and compliance, with geometry, add-ons and options tailored to the wishes of the customer, something that can only be done with metal frames. We also offer tubing with ovalized and special hydroformed cross sections to further fine-tune the properties of the frame.

 

As the use of vacuum room costs higher, Titanium Pipe so the general use of inert gas protection method. The protective gases are mainly helium and argon, because the helium price is higher than the argon, in general, is not a special requirement of titanium alloy welded joints and heat affected zone, Titanium Pipe the use of high purity argon to protect the oxidation can prevent oxidation.

 

Titanium alloy: based on titanium alloy as base to join other elements, and is mainly used to produce aircraft engine compressor components, rockets and missiles and high-speed plane of industrial structure and other corrosion resistant structure materials.Titanium alloys have high strength and low density, good mechanical properties, good toughness and corrosion resistance.However, titanium alloy cutting processing is difficult, in hot processing, it is very easy to absorb the hydrogen and oxygen nitrogen and other impurities, the production process is complicated.
