Abstract

The invention provides a laser welding method, and relates to the technical field of brass welding. The laser welding method comprises the steps that welding faces of two brass workpieces to be welded subjected to surface cleaning are spliced and fixed; and a single-mode fiber laser is adopted for swing welding along the to-be-welded joint of the two brass workpieces to be welded according to a preset swing path. The laser welding method is simple in welding procedure and high in welding efficiency.

Description

technical field [0001] The invention relates to the technical field of brass welding, in particular to a laser welding method. Background technique [0002] Brass is an alloy composed mainly of copper and zinc. Brass has strong wear resistance, so it is often widely used in the manufacture of water tank belts, water supply and drainage pipes, bellows, serpentine pipes, condenser pipes, cartridge cases and All kinds of punched products with complex shapes, small hardware, etc. [0003] However, due to the large difference between the boiling points of copper and zinc in brass, among them, the boiling point of zinc is lower, and the zinc element is easily evaporated to form zinc vapor during the welding process, and a large amount of zinc vapor is easy to break through the surface tension of the molten pool, accompanied by molten liquid If they are sprayed out from the weld pool together, it will cause defects such as zinc element burning, weld sag, splash, undercut, etc., wh...
