Straight tube butt welding with cold wire conditions is an increasingly used welding process in fabrication or manufacturing industries to increase productivity and improve weld quality. The existing literature studies on straight tube butt welding with cold wire conditions of T12 joints of boiler tubes are still limited. Hence, this study investigated the straight tube butt welding using cold wire conditions of T12 steel joints. Ultimate tensile strength and Vickers microhardness were measured to test the feasibility of butt-welded joints of T12. The weldment is characterized using Optical Microscopy (OM) to study the surface morphologies.

摘要

Straight tube butt welding with cold wire conditions is an increasingly used welding process in fabrication or manufacturing industries to increase productivity and improve weld quality. The existing literature studies on straight tube butt welding with cold wire conditions of T12 joints of boiler tubes are still limited. Hence, this study investigated the straight tube butt welding using cold wire conditions of T12 steel joints. Ultimate tensile strength and Vickers microhardness were measured to test the feasibility of butt-welded joints of T12. The weldment is characterized using Optical Microscopy (OM) to study the surface morphologies.
