Forming Characteristics of Laser Welded Tailored Blanks
레이저 용접 테일러드 블랭크의 성형특성
Abstract
In order to analyze the forming characteristics of laser welded tailored blanks, laser welded blanks of different thickness and strength combinations were prepared and tensile, stretching, stretch flanging and deep drawing tests were done. The tensile elongation perpendicular to the weld line, stretching and stretch flanging formability decreased with increasing the deformation restraining force (strength
