Titanium alloy frame manufacturing relies on a high-purity inert gas protection process. The welding process is carried out in a sealed chamber with an argon content ≥99.999%, combined with pulse TIG welding equipment, to control the heat-affected zone within 0.8mm. The key process uses a back argon gas shielding technique to ensure the weld is oxidation-resistant on both sides. Post-weld multi-stage heat treatment is performed: first, stress is relieved at 800℃±5℃, then β-phase distribution is optimized through aging treatment at 550℃±3℃. The weld strength of the pipe fittings processed by this process reaches 95% of the base material, and the deformation is <0.15mm/300mm.
