Stud Welder is a very efficient method of welding fasteners to a metal surface. The metal where we can use this technique is stainless steel, mild steel, copper, brass, aluminum, and titanium. The stud welding machine removes the process of drilling, punching, riveting, gluing and taping etc. In this process, a small projection made from the stud once came into contact with metal the stored energy from capacitor discharge at the area of contact of the stud with metal making a molten pool of metal. At this point of time, the Stud is pushed with spring method in the molten pool of metal and get welded at the surface without making any mark at the back of workpiece.
