Beschreibung
Zusammenfassung:	The invention provides a scanning galvanometer laser-high frequency pulse TIG composite welding method. A steel plate to be welded is made into a welding groove, and assembling and cleaning are carried out. A first workpiece to be welded is in butt joint with a second workpiece to be welded. The first workpiece to be welded and the second workpiece to be welded are thick steel plates. A welding seam to be welded with the selected width and length is formed between the two workpieces to be welded. A welding wire is used, laser beams generated by a scanning galvanometer laser-high frequency pulse TIG composite welding gun and a TIG welding gun are used for travelling welding for the welding seam in the direction from one end to the other end, and a mode of a straight-line swing, a circular swing or a "8-shaped" swing is adopted in the welding process. According to the scanning galvanometer laser-high frequency pulse TIG composite welding method, scanning galvanometer laser-high frequencypulse TIG composite weld
