Remote Laser Welding of Steel and Aluminum Alloys

Remote laser welded fillet and I-seams at overlapped metal sheets are important joints for body-in-white production. Under ideal conditions such joints can be created in a welding-friendly PA (flat) position with a zero-gap between the parts. In Fig. 1, an example of a fillet welding process incl. a cross section of a typical weld seam at an aluminum door is shown.
