Hardly visible to the naked eye and therefore often underestimated: The surface condition of welding wires has a strong influence on the feeding properties, current contact, arc stability and welding result.
Using measurement data and high-resolution images, an attempt is made to find answers to the following questions: Are matte or shiny surfaces better for GMA welding?
How do you differentiate between "clean" and "dirty" wires during incoming inspection? What are the effects of a contaminated wire surface during TIG and MAG welding?
