Abstract

The invention relates to the field of welding, in particular to a laser enhancement device and an electric arc welding system. The laser enhancement device comprises an optical element, a focusing lens, an optical connector and a driving unit. Laser light can sequentially pass through the optical connector, the optical element and the focusing lens to form a laser beam. The driving unit can drive the optical element to rotate so as to rotate the laser beam. The electric arc welding system comprises the laser enhancement device. The laser beam is driven by the driving unit to rotate along a preset path. Molten drops are transitioned at uniform sizes and frequencies. The laser beam heats the surface of a to-be-welded parent metal zone while cleaning the surface of the to-be-welded parent metal zone, so that the temperature of the surface of the to-be-welded parent metal zone is increased, the stability of the welding process is improved, and the welding quality is improved; and electric arcs are more stable by increasing the temperature of gas of the to-be-welded zone. The welding quality with the same fusion depth is achieved with low current, and low-spatter welding is achieved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a laser intensifying device and an arc welding system. Background technique [0002] In the traditional arc processing technology, under the action of the arc, the stability of the droplet generated at the end of the welding wire directly determines the stability of the welding process. In the prior art, during the welding process, the droplet transfer is uneven, sometimes large particles transfer, sometimes short-circuit transfer, and the corresponding welding process is also unstable, which will inevitably cause serious welding spatter and welding defects, directly affecting the welding process. Quality of products. Contents of the invention [0003] The object of the present invention is to provide a laser intensifying device and an arc welding system. It aims to improve the problem of poor quality of welded products obtained by existing laser welding. [0004] The invention provid...
