gas shield welding instead of manual electrode arc welding for stainless steel overlay welding on the composite plate pressure vessel’s cylinder longitudinal ring seam

gas shield welding.This paper mainly analyzes the welding quality in different analysis of overlap.To test is found that 50% overlap joint ratio is suitable.
