Metal pipe protection welding tool

The utility model discloses a protective welding tool for metal pipes, relates to the technical field of metal welding, and aims to solve the problem that parts are difficult to coordinate and unify in the aspects of clamping and inert gas protection when the metal pipes are welded. The metal pipe protection welding tool comprises a supporting assembly and a welding assembly, the inert gas protection assembly is arranged on the supporting assembly, and the inert gas protection assembly is used for introducing inert gas into the metal pipe to be welded; and the positioning assembly is arranged on the inert gas protection assembly and used for positioning and fixing the to-be-welded metal pipe and sealing the two ends of the to-be-welded metal pipe. The metal pipe protection welding tool is used for coordinating and unifying clamping and inert gas protection of parts in the welding process, and the welding efficiency is improved. 本实用新型公开一种金属管类保护焊接工装，涉及金属焊接技术领域，以解决金属管类焊接时，零件在装夹、惰性气体保护方面难以协调统一的问题。所述金属管类保护焊接工装包括：支
