Description
Technical Field
The utility model relates to the field of cleaning and welding, in particular to an integrated working head for MIG welding and laser cleaning, which is suitable for manufacturing materials or parts of aluminum alloy, titanium alloy and the like needing pre-welding and post-welding cleaning.
Background
MIG welding (melt inert gas welding) is an arc welding method that uses an externally applied gas as an arc medium and protects a molten metal drop, a weld pool, and a high temperature metal in a welding zone, and melts a wire and a base metal by using an arc burned between a continuously fed wire and a workpiece to be welded as a heat source. During MIG welding, shielding gas is continuously delivered to the weld zone through the gun nozzle, protecting the arc, the molten pool and the base metal in the vicinity from the deleterious effects of ambient air. The welding wire is continuously melted and should be transferred into a welding pool in the form of molten drops, and the molten welding wire is fused with molten base metal and condensed to form weld metal. Almost no oxidation burn-out exists in the welding process, only a small amount of evaporation loss exists, the metallurgical process is simpler, and the labor productivity is high; however, MIG welding has no deoxidizing and dehydrogenation effects, is sensitive to oil and rust on a base metal and a welding wire, and is easy to form defects, so that the surface cleaning requirement of welding materials is particularly strict.
The surface of the welded part should be cleaned before welding to remove the oxide film and oil dirt, so as to prevent air holes and slag inclusion in the welded seam. The welding parts are left behind after welding and adjacent residual flux and welding slag, and the welding parts need to be cleaned up in time, otherwise, under the action of air and moisture, the residual solvent and the welding slag can damage a metal film with an anti-corrosion effect, and the welding parts are corroded drastically. Corresponding welding cleaning is required.
The conventional cleaning method before MIG welding includes: mechanical friction cleaning, chemical corrosion cleaning, liquid-solid strong impact cleaning, high-frequency ultrasonic cleaning and the like, and the traditional cleaning methods have the problems of low working efficiency, environmental pollution, substrate damage and the like. Moreover, these conventional cleaning methods are complicated in equipment, and it is difficult to combine the cleaning equipment with the MIG welding to complete equipment of the corresponding welding process.
Therefore, how to provide a better cleaning mode for the pre-welding cleaning of MIG welding and to provide a complete set of corresponding welding procedures in combination with the pre-welding cleaning and MIG welding is a problem to be solved.
