Abstract

About the thesis, we made the welding experiment by using three kinds of test pieces, the actual size and the diaphragm and the butt joint. Then, we examined the influence to strength, cooling time and carbon equivalent of weld metal by welding conditions about the difference of test pieces. We calculated estimate equation that estimate cooling time and chemical component. And we came out strength of weld metal is estimated by those numerically values. Consequently, we got strength of weld metal is estimated by heat input, interpass temperature, carbon equivarent of welding wire and shape of test piece.
