This is a fast and economical method of welding studs of various shapes and diameters onto the parent material. Stud welding is used for fixing studs onto the parent material without perforation. Normally for fixing studs and fasteners you will have to adopt operations such as drilling and tapping. By using stud welding you can completely avoid these operations. There are two main methods of stud welding i.e. Capacitor discharge stud welding and Drawn Arc stud welding. The selection of the process depends on thickness of the parent material, diameter of the stud, weld strength required and welding aesthetics requirement. The capacitor discharge method is used for thinner material and drawn arc method is used for higher diameter studs and thicker parent material.
