Abstract

PURPOSE:To form an excellent weld bead at high speed, by melting and smoothing the bead surface layer by TIG welding after forming a bead on the steel plate by MIG welding in a shielding gas containing O2 and H2 by specified contents in Ar. CONSTITUTION:While feeding Ar containing O2 by 0.2-2wt% and H2 by 0.4- 4% from a gas feed hole 4 in a trailer shield nozzle 3 as shielding gas, non-oxidation weld bead 7 is formed on a steel plate by means of a MIG welding torch 1 having an electrode wire 2. A TIG welding torch 5 which is connected to said torch 1 in a position behind the same MIG welding torch 1 and has W electrode 6 is moved to the left at high speed, and the surface layer of the non-oxidation weld bead 7 is melted and smoothed by the torch 5. In this method, high-speed welding may be performed stably, and an excellent weld bead free of undercut may be easily obtained.
