The invention belongs to the technical field of welding equipment, and discloses a titanium alloy welding platform and a titanium alloy welding method. The titanium alloy welding platform comprises a supporting table, an air groove assembly and an air cover assembly. Protective gas can be introduced into the gas groove assembly and the gas cover assembly of the titanium alloy welding platform, the front face areas and the back face areas of the two sample plates to be welded can be filled with the protective gas for protection, and a welding seam and near-seam areas on the two sides of the welding seam can be effectively protected by the gas. The welding method can protect a thermal-state welding seam, a back welding seam and a near-seam area from being oxidized or nitrided when the titanium alloy jointed plate is welded, can effectively improve the welding seam quality after welding, prevents the welding seam from being oxidized and blued, reduces welding deformation, avoids post-welding ...
