stud welding is a form of spot welding where a bolt or specially formed nut is welded on to another metal part. The bolts may be automatically fed into the spot welder. Weld nuts generally have a flange with small nubs that melt to form the weld. Studs have a necked down, unthreaded area for the same purpose. Weld studs are used in stud welding systems. Capacitor discharge weld studs range from 14 gauge to 3/8` diameter. They can come in many different lengths ranging from 1/4` to 5` and larger. The have a `tip` on the weld end of the stud that is two-fold in purpose. It acts as a timing device to keep the stud off of the base material and It disintegrates when the trigger is pulled on the gun. When it disintegrates it becomes a molten material and helps solidify the weld to the base material. Arc studs range from a #8 to 1 1/4` diameter. The lengths are variable from 3/8` to 60` (for deformed bars). Arc studs are typically loaded with an aluminum flux ball on the weld end which aids in the welding process. Stud welding is also known as stud arc welding. It is a process by which a stud and another piece of metal are joined together. Stud welding is usually joined to a flat plate by using the stud as one of the electrodes. The polarity used in stud welding depends on the type of metal being used. if you are going to weld aluminum for example you would usually use direct-current electrode positive(DCEP). While for steel you would use direct-current electrode negative (DCEN).
