When Welding Titanium Rods, It Must Be Ensured

Due to the special physical and chemical properties of titanium rods, the welding process is very different from that of other metals. Titanium welding is a TiG welding process that uses inert argon gas to effectively protect the welding area. Before using argon gas, check the factory certificate on the bottle to verify the purity index of the argon gas, and then check whether the bottle valve is leaking. Or failure of the first image.
When welding titanium rods, you must ensure:
(1) The metal in the welding area is not contaminated by active gases N, 0, H and harmful impurity elements C, Fe, Mn, etc. above 250°C.
(2) Argon: industrial grade pure argon, with a purity of not less than 99.98% and a water content of less than 50Mg/m3.
(3) Coarse grain structure cannot be formed.
(4) Large welding residual stress and residual deformation cannot be generated. Therefore, the welding process must be carried out in accordance with the predetermined construction sequence, strictly according to the process quality management standards, and the quality control of the whole process must be implemented. The factors of human, machine, material and method are all under good control, so that within a reasonable construction period, Ensure the welding quality of titanium tubes.
