titanium tube welding is the use of emotional gas on the welding area to effectively protect the TiG welding process

Source:

Titanium tube welding technology: titanium tube welding is the use of emotional gas on the welding area to effectively protect the TiG welding process, because titanium has a special physical and chemical properties, and thus the welding process and other metals there is a big difference. Titanium tube welding must ensure that: (1) welding area of metal at 250 ℃ or more from the active gas N, 0, H and harmful impurities such as C, Fe, Mn and other pollution. (2) can not form coarse grain structure. (3) can not produce a large welding residual stress and residual deformation. Therefore, the welding process to be in accordance with the scheduled construction sequence, in strict accordance with the process of quality management standards, the implementation of the whole process of quality control. So that people, machines, materials, France, the factors are in a well-controlled state, which in a reasonable period of time to ensure the quality of titanium tube welding.
