Method and System for the Remote Laser Welding of Two Coated Sheets

摘要

A method is provided for the remote laser welding of two coated sheets, wherein by way of a scanner, a laser beam is directed at the sheets to be connected to each other and guided on the sheets. The sheets are connected to each other by producing an end fillet weld on a lap joint. The continuous production of the weld is recorded by a camera and, if necessary, the path of the laser beam is corrected and adapted to a target weld course on the basis of an automatic evaluation of the recorded images.

主权项

1. A method for laser remote welding of two coated sheets, the method comprising the acts of:
directing a laser beam onto the two coated sheets to be joined to one another and guiding the laser beam on the two sheets by way of a scanner; producing an end fillet weld on a lap joint between the two sheets in order to join the two sheets to one another; recording images of a continuous production of the end fillet weld, via an imaging unit; and correcting and matching a path of the laser beam to a desired weld course, if required, based on an automatic evaluation of the images recorded by the imaging unit of the continuous production of the end fillet weld.
