Stud Welding Process

Stud welding is defined as a method of arc welding in which "permits rapid attachment of studs and other fasteners to a structure without piercing the structure metal". There is no filler metal, and shielding gas, flux, or ceramic shield around the stud are all optional. Once the metals on the stud and the base piece are heated enough to be joined, they are pressed together in order to fuse them mutually. The stud is sometimes encased on the end with a ceramic cuff in order to defend the arc and the welding surfaces from the surrounding environment. For some while, this form of arc welding is not a true disparity of it. Stud welding uses principles from arc welding and from forge welding. An arc is used to heat the metal, but then a power is used to adhere the pieces together.

In contrast to drilling and tapping, stud welding in superior. The base metal is not weakened and a water tight seal is not destroyed, as is the case with drilling and tapping. Also, costs and time are minimized when compared to the other two. Robots are now being used to place and set the studs, which also decreases time. Every location can be welded from, but vertical and overhead positions are not easily finished. A variety of metals can be used as well, not just ferrous metals.
