Capacity discharge stud welding and arc stud welding are the two types of stud welding systems offered by High Speed Fastening . Capacity discharge stud welding uses the same metallurgical aspects and basic principles as used in any other welding procedure. The weld gun, used in capacitor discharge stud welding offered by High Speed Fastening is activated leading to a special precision weld tip that initiates a controlled electric. This weld tip from the welder capacitor bank melts a portion of the base metal and the end of the stud.
The stud used in capacitor discharge stud welding offered by High Speed Fastening is held in place as the molten metal instantly solidifies accomplishing high quality fusion weld. In this case, the weld is much stronger than the stud itself. CD stud welding offered by High Speed Fastening is generally used to weld studs with small diameter and thin base metals, especially in studs where reverse side is not permitted.
The entire CD stud welding systems offered by High Speed Fastening is completed in milliseconds, thus enabling welds to be made into thin material without burn-through, reverse side discolouration and pronounced distortion. CD studs can be manufactured in any shape as long as one end of the stud is designed for CD welding.
