Handwork tungsten electrode argon-arc welding swinging rolling welding method

The invention provides a manual tungsten electrode argon arc welding swing rolling welding method in which the dimension of the magnetic nozzle of a welding gun is selected according to the size of the groove and the welding material; the magnetic nozzle is a supporting point for swing rolling; spot welding preheated by electric arc is carried out after high-frequency arc ignition; by swinging the magnetic nozzle by the wrist of the operator, the magnetic nozzle is closely attached to the surface of the groove and is swung from the left side to the right side along the center of the welding seam; the magnetic nozzle is swung to the left side and the right side and motions forwards, the current is attenuated, and the arc is turned off after the molten pool is contracted. The manual tungsten electrode argon arc welding swing rolling welding method provided by the invention can improve the welding quality.
