CD Studwelding is where capacitors are used to quickly discharge electrical energy through a threaded or unthreaded weld stud. The electrical energy liquifies the pip of the stud. Simultaneously, spring pressure in the hand tool forces the stud down into the molten pool, forming a weld that is stronger than the parent material. Stud welding is only possible onto
