Abstract

The invention provides a laser-arc fuse wire welding process for avoiding slag inclusion. The laser-arc fuse wire welding process for avoiding slag inclusion comprises the following steps of S1, fixing a workpiece, and polishing a workpiece welding part; S2, spraying a cleaning agent for the welding part; S3, preheating before welding: preheating the workpiece before welding; S4, activating the welding surface: after stopping heating, quickly spraying an active agent; S5, after drying the welding part, adopting a welding rod for welding; and S6, cooling for shaping. The invention aims to research and develop the laser-arc fuse wire welding process for avoiding slag inclusion from the welding source in order to reduce slag inclusion of the die workpiece and reduce the difficulty and the necessity of a follow-up slag inclusion removal process.

Description

technical field [0001] The invention relates to the technical field of automatic mold processing, in particular to a laser arc fuse welding process for avoiding slag inclusion.
