Aimming at CO,2, gas shielded welding flux cored wire pipe butt weld fixed 45 degree appearance and internal quality of weld forming is studied,worked out a complete set of process operating methods. Focuses on the important relationship between the internal quality of weld forming and weld seam forming,each layer of the multilayer weld will directly affect the internal quality of weld,welding operation by controlling welding to improve the qualified rate of weld appearance quality and X ray detection,play a guiding role in the training of teaching and practice.
