Patent abstract
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.
