초고장력 강판의 CMT 용접 조건과 용접 이음부 분석

다국어 초록 (Multilingual Abstract)

Lightweight vehicles are essential in the automotive industry and are receiving increasing attention in research studies. In particular, investigations on the welding of advanced high-strength steel (AHSS) have been conducted recently. In this study, the lap joint welding of AHSS was performed through a cold-metal transfer welding process, and the defects in the cross-section were analyzed to determine the optimum welding condition. Additionally, tensile tests were carried out under the selected welding conditions to check if the weld had a similar tensile strength to that of the base material. Fracture mainly occurred at the boundary of the heat-affected zone, which was analyzed through the increase in hardness.
