Description

Technical Field

[0001] The utility model belongs to the technical field of drying devices, in particular to a drying device for welding wires. Background Art

[0002] During the welding process, the quality of the welding wire has a crucial impact on the welding effect. The welding wire is easy to absorb moisture during storage and use, which will cause defects such as pores and inclusions during welding, affecting the welding quality. Therefore, the welding wire needs to be dried before use to remove moisture and impurities on its surface to ensure the stability of the welding quality.

[0003] However, traditional welding wire drying devices usually only have a conveying roller at one end of the heating pipe to feed the welding wire into the heating pipe. During the welding wire feeding process, due to the lack of effective clamping, the position of the welding wire in the heating pipe is unstable, and the hot air cannot evenly cover the surface of the welding wire, resulting in insufficient drying of certain parts, thereby reducing the drying effect of the welding wire.
