Welded Sleeve is a type of fastening that is used to create a fastening unit on sheet metals, to which they are mounted by rapid welding by capacitor or butt welding. A thin tip at the base of the stud is required, firstly as a material for melting, and secondly to form the distance between the materials for forming a welding bath evenly over the entire plane of the base of the stud.
The scope of us is very wide, but the greatest application has been found in the production of electrical equipment.
The material is high-strength steel. The high strength class 4.8 allows the use of bolts in highly loaded connections.
Plating - The copper plating of the pin creates low contact resistance and better current conduction, which greatly speeds up the welding process. Also, the copper coating improves the characteristics of the welds, increasing the resistance to tearing and shock loads.
