Scope
Main technical content: This document specifies the qualification requirements for personnel engaged in laser-arc hybrid welding of aluminum alloys in rail vehicles, the requirements for process equipment, pre-welding preparation, welding process methods, post-welding treatment, and defect repair methods. Laser-arc hybrid welding is a welding method that achieves synergistic effects by using laser beams and arc energy sources synchronously or alternately, combining the deep melting of high-energy density lasers and the strong bridging ability of arcs. This document is applicable to laser-MIG/MIG hybrid welding of aluminum alloys in rail vehicles.
