| Abstract | Usage of new kinds of pipe steels, such as X80-X100 and increases of pipe wall thickness require new kinds of pipeline welding technologies, which can provide high process productivity as well as fit the requirements for weld seam material properties. Technology of hybrid laser-MAG welding is one of possible solution for this task. A prototype of industrial machine for hybrid welding of pipeline has been developed on the base of joining of 20 kW fiber laser with 500 A inverter arc power unit. The hybrid welding module move along soft direction belt, which allow easy copy of shape of the pipe. Usage of seam tracking and laser following after the arc allow weld with gap in the joint with necessary quality that was proved by the results of mechanic tests. Developed technology combine hybrid welding of root pass with filling arc pass by the same machine. Peculiarity of welding in different space positions has been discussed also. |
