Technical Field

[0001] The utility model belongs to the technical field of welding, in particular to a wire feeding wheel structure and a wire feeding machine. Background Art

[0002] The wire feeding speed of the laser welding machine is an important process parameter for welding. The joint width and weld height increase during laser wire welding are mainly formed by the deposited metal of the welding wire. The determination of the wire feeding speed is affected by factors such as welding speed, joint gap, and wire diameter. If the wire feeding speed is too fast or too slow, it will lead to too much or too little molten metal, which will affect the interaction between the laser, the base material and the welding wire and the formation of the weld. How to improve the wire feeding stability is a problem that needs to be continuously solved. Utility Model Content
