A Study of Sheet Hydro-forming Using High Strength Steel Sheets

Digital Laser Welding System for Automobile Side Panel

“…Welding structure is considered as an important factor in case of car body strength. Also, as a part of efforts to lighten car body in automotive enterprises, they try to make car body using new technologies such as TWB(Tailor Welded Blank) (Ku et al, 2004;Zhang, 2006) or hydro forming (Gao et al, 2006;Park et al, 2002;Saito et al, 2006;Suh et al, 2006) which can minimize the overlapping areas of welding. At the same time, they attempt to lighten car body by substituting the existing steel-oriented panel with new materials such as aluminum or magnesium.…”
