Problems solved by technology

The disadvantage of this wire feeding mechanism is that the contact between the lower pressure roller 1 and the upper pressure roller 3 of the wire feeding mechanism and the aluminum welding wire 2 is point contact, and the contact area is small. Slip between the small roller and the aluminum welding wire, resulting in uneven wire feeding; excessive pressure will cause indentation or deformation of the aluminum welding wire, and the resistance of the aluminum welding wire will increase after entering the guide wire tip, and the aluminum welding wire will deflect near the light spot, and even block the wire , affecting the stability of the welding process

Description

technical field [0001] The invention relates to a laser welding wire feeding mechanism, which belongs to the field of supporting devices for laser processing. Background technique [0002] With the development of science and technology, in the transportation manufacturing industries such as aerospace, navigation and automobiles, in order to reduce the weight of the vehicle and improve the transportation capacity, more and more light metal materials are used. As an important light metal material, high-strength aluminum alloy is widely used in the transportation manufacturing industry because of its excellent physical, chemical and mechanical properties. For a long time, the backward riveting process is still used in the connection of aluminum alloy plate structures, resulting in an increase in the weight of the structure, while the traditional fusion welding method is used to weld aluminum alloys, resulting in large deformation of the welded structure and poor performance of ...
