Welding Wire is made of tin alloy and additives in two parts, the alloy is divided into tin and lead, lead-free additives evenly poured into the middle of the tin alloy.
Different types of Welding Wire additives will be different additives part is to improve the Welding Wire in the welding process of secondary heat conduction, removal of oxidation, reducing the surface tension of the material to be welded, the surface of the welding material is removed, increasing the welding area.
I will always share somw knowledge about Plasma Welding Machine,Carbon Gouging Rods Gouging Torch.If you like my share, welcome to follow me and hope to get your suggestions
