This is a process of welding stud (a headless threaded bolt) or stud-like pieces (e.g. bolts, screws, rivets, rods, etc.) to flat workpieces like plates. Its a unique process which combines arc and forge welding processes and results in tremendous cost saving when compared to the conventional methods like drilling and tapping. Stud welding was first used by British Navy in 1918 but its regular and extensive use started from 1938. There are four variations of the process viz., capacitor discharge stud welding, the drawn arc capacitor discharge stud welding, the consumable ferrule stud welding and the drawn arc stud welding. The last variation of the process is the most popular and the following description pertains to that only.
