매쉬심 용접판재의 성형 특성에 관한 실험적 연구

An Experimental Study for Forming Characteristics of Mash Seam Welding Sheets

  • 발행 : 2000.11.01

초록

In recent automotive industry, vehicle weight can be reduced by one-step forming of tailored blanks welded with two or more sheets of metal blanks. Mash seam welding shows an overlap joint, a much wider welding area, and heat affected zone(HAZ) than a laser welding. This paper deals with the forming characteristics of mash seam welded tailored blanks. Mash seam welded blanks of same or different thickness combinations were prepared, and tensile, hardness, erichsen, and dome stretching tests were done.
