Description

Technical Field

[0001] The invention relates to the technical field of welding wire oiling, in particular to an automatic welding wire oiling device. Background Art

[0002] Welding wire oiling is a method of treating the surface of the welding wire during the welding wire processing in order to improve the welding quality and processability. This oiling is usually applied to the surface of the welding wire, and the welding wire oiling can prevent the surface of the welding wire from oxidizing during the welding process. Oxidation will affect the quality of welding and introduce poor welds, so oiling can protect the surface of the welding wire and ensure the stability and quality of welding. Some oiling can improve the conductivity of the welding wire, help to better control the welding arc and current, thereby improving the stability and consistency of welding. Proper welding wire oiling can also reduce spatter during welding. This is very helpful for keeping the welding area clean and reducing subsequent cleaning work, and also helps to improve welding efficiency. Usually, oiling can be done manually or automatically. The automated oiling equipment in the prior art still requires manual continuous pulling of the welding wire to cooperate with the oiling. At the same time, the welding wire needs to be straightened before the oiling process to facilitate full oiling. Summary of the invention
