摘要: Abstract Laser-twin-arc hybrid welding, which combines the techniques of laser welding and twin-arc is an emerging technology. In this study, synchronous information including spectral signal, high-speed photography electrical signal used to explore physical interaction between arcs alternate burning in laser-twin-arc process, effect combined arc/laser heat source on process was analyzed. The results indicated that provides a conductive, stable plasma channel for arcs, can influence arc shape, slow down droplet transfer, reduce resistivity stabilize arcs. Electron temperature from 7000 K 17000 K, significantly influenced by parameters. acquires deeper penetration wider HAZ than with alone.
