Patent ID: 8471173

Claim:
A method for welding using a laser hybrid welding process, comprising the steps of: performing at least one laser process; calculating a time for a delay of a start of at least one shielding gas welding process; delaying the start of said at least one shielding gas welding process by calculating the time for delay based upon an input distance between a laser unit and a shielding gas unit, and a defined welding speed; performing said at least one shielding gas welding process comprising a MIG/MAG welding process which is formed by a cold-metal transfer welding process including a forward/rearward movement of a welding wire, increasing a current in said welding wire during said forward movement; causing a droplet to be released; wherein an energy input via the shielding gas welding process is reduced because of the droplet detachment being effected by the rearward movement of the welding wire; supplying a filler material to the welding site via the shielding gas welding process, positioning a set of coated sheet metals relative to each other in a gap-free manner, wherein said filler material used for the shielding gas welding process is comprised of a welding wire having at least one of a zinc carbon or aluminum content; superimposing and clamping said set of coated sheet metals together via a clamping device which is arranged on a welding head and wherein the clamping device is comprised of a roller and a clamping strap.
