Laser welding of thick steel plates

By combining conventional welding processes with laser processing, material, work steps and energy can be saved. When a GMA torch is combined with a laser beam, the light arc is also stabilized. The welding seam is deeper, and the welding speed is increased. Especially for thick metal plates, both the welding time and energy can be considerably reduced.

We show how steel plates with thicknesses up to 20 mm and aluminum plates with thicknesses up to 12 mm can be welded on one side. The process can be used with the usual gap and tolerance measurements. Since material removal for edge preparation can be reduced, filler material can be saved. Lower prices and a higher efficiency make hybrid welding attractive for long seam lengths, for example for pipelines and ship construction. Thus, construction costs can be reduced by using the hybrid welding process.
