摘要: While steel sheets are positioned and held by a holding mechanism, first laser beam is applied to heating region of the sheet space from other predetermined distance. A second welding weld sheets. An amount heat beam, moving speed focused spot diameter set keep irradiated with in an unmelted state plastically deform sheet.
