Process. The process involves an arc being ignited, between the face of the stud, and the surface of the work piece. Once both parts are melted, the stud is smoothly pressed against the work piece and joined together. Welding elements like threaded studs, pins, tapped pads, etc. are welded by an arc without additional material being required. As the stud is joined with the work piece over the whole surface of the stud, the strength of the joint is even higher than the base material or the stud.
Did you ever wonder why stud welding was invented?
Here are some of the reasons why the technology was created:
Drilling & Tapping
These processes are very slow. Thicker parent material is required, as are longer studs.
Through Bolting
Requires two handed assembly and access from both sides. Holes need to be punched and deburred in parent material. Bolt heads are unsightly and stains can come from the bolt holes. The assembly is not leak-proof and the parent material is weakened by the presence of the holes.
