Laser-welded profile Welser Profile

As well as open sections, Welser produce welded tube profiles. The seam welding of tubes increases their strength during twisting or bending, in comparison to open pipe sections. There are two welding methods utilised: high-frequency welding and laser welding. Which method is used depends on various factors, such as material grade, shape of the section, position and requirements of the weld seam. Laser welding possibilities: longitudinal seam welding of special profile tubes, welding together of components of different material grades and strengths. Mobile CO2 laser rigs enable continuous laser welding as well as the capability to produce multi-chambered profiles on-line direct from the rolling machines.
