Description

technical field

[0001] The invention belongs to the technical field of welding wire production, and in particular relates to a method for inspecting and evaluating the quality of the copper plating layer of welding wire. Background technique

[0002] The product standards related to welding wire have clear technical requirements for chemical composition, dimensional accuracy, stiffness and bending performance, but there are no specific requirements for the protection of welding wire surface. There are also bare products on the market that do not need a protective layer, which are only suitable for customers who are ready to use at any time and have a short storage period. Continuous production line companies usually use copper plating protection, which generally has a half-year shelf life. In the early stage of welding wire production, the color and brightness of the copper plating layer fluctuate greatly, and the quality is very unstable.
