Longitudinal seam welding

Longitudinal Seam Laser Welding


For shell or tube welding a pipe is placed onto the roller support installed at the trolleys.

For plate welding the trolleys are equipped with the adjustment frame. The plate is placed onto the frame, which has plane adjustment with reference to the surface level.

To make it convenient for operator to adjust a welded part position before welding, there is a portable control panel in close vicinity to the part.

Due to combination of fiber laser and power supply for arc welding it is possible to perform laser or hybrid (laser-arc) welding.
