Metal profile LASER-WELDED

Laser-welded special profiles Laser-welded profiles are welded to one special profile from two or more material strips without any additives. The construction steel strip material can be cut to any required length from coils with width ranging from 3 mm to 20 mm. Above this material width and for stainless steels from 14mm on, plate-sheets are usually used as primary material, since they are regularly available in 6 to 12 m lengths. During laser welding, the contact surfaces of the steel strips are directly welded to one another. This is why the 8 – 10 mm penetration depth of the laser on each side barely leaves any visible weld seam. Laser welded profiles are geometrically flexible and manufacturable in small and large quantities. Compared to conventional welded profiles, laser-welded profiles offer much tighter tolerances and lower stresses. The profiles can be optimised for mass inside the profile geometry by welding of different steel strip widths. They are sharp-edged independently of the employed material width. Outside weld seams are machined and almost invisible during close inspection.
