| Abstract: | This paper makes use of TIG welding material, namely, titanium alloy sheet with the thickness of 1.2mm, protects the positive and negative sides with inert gas, and requires single face welding and double face shaping. When welding, it adopts several groups of different welding parame- ters for welding test, conducts transverse cutting and grinding into metallographic phase specimen, and observes the mierostruetures of the fusion zone of different samples by SEM. After that, the author ana- lyzes its compositions, and then by comparing their microstructure characteristics, rationally evaluates the optimal welding parameters to weld 1.2mm Titanium alloy sheet. |
