Laser welding

Simultaneously with the rolling, we performed continuous laser welding directly in a line during rolling. The thickness of a profile suitable for welding ranges from 1 to 2.5 mm. A suitable profile intended for the laser welding can be made of galvanised as well as black cold- or hot-rolled steel sheet. When using galvanised steel, the weld is then anti-corrosion treated. The laser welding technology allows producing complicated shape profiles.
