摘要： The present invention provides a laser welding method for steel sheets. The laser welding method includes irradiating a low heat input laser beam to a weld zone with a uniform welding pattern of a zigzag shape, with a constant pitch, and with a constant welding speed, so that autogenous welding may be achieved without a feed wire, such that cost of material may be reduced and joinability and performance may be improved.
摘要翻译：本发明提供一种钢板的激光焊接方法。激光焊接方法包括以均匀的间距和恒定的焊接速度以均匀的锯齿形状的焊接图形将低热输入激光束照射到焊接区域，从而可以在没有馈电线的情况下实现自身焊接，从而可以降低材料成本，并且可以提高连接性和性能。

摘要： A method of laser welding where two steel sheets are welded by a laser beam after the two steel sheets are overlapped with a predetermined gap is disclosed.The method includes: a stitch welding step where a laser beam of focal region is irradiated along a welding portion of the upper steel sheet and the lower steel sheet such that a molten slot is formed at the upper steel sheet along the welding portion and an heat expansion portion is formed at the lower steel sheet along the welding portion by thermal conduction; and a pattern welding step where the laser beam of focal region is irradiated along the welding portion with a predetermined pattern such that an edge of the molten slot formed at the upper steel sheet is melted together with the heat expansion portion of the lower steel sheet so as to form a molten pool.
