In addition, because the majority of the stud welding process is automated, any operator, regardless of his or her skill level, can perform it. The operator simply initiates the weld cycle and reloads as needed. This automation of the stud welding process provides a repeatable, consistent result for each piece.

Many manufacturers rely on stud welding because it's portable. If a stud needs to be welded, the manufacturer simply brings the stud-welding tool right into the assembly line. There's no need to do this work offline. This means more factory throughput, lower manufacturing costs, high and more consistent product quality, and ultimately, faster-time-to-market of the finished product.

Stud welding in the auto industry

Automotive manufacturers use stud welding in various ways. For example, manufacturers use a variety of fastening methods to attach fasteners to sheet metal in the car body, for applications such as cable harnesses and grounding of electrical systems. By replacing projection welding of small stamped brackets with a stud-welding derivative called TARC (bracket welding), manufacturers can literally reach into the car body to place the fastener in position. This reduces up-front tool and fixture costs by an estimated 30 to 40%. Moreover, this process uses smaller fasteners, which reduce the weight of the component itself by 50%. Using lighter components improves the fuel economy of the vehicle — an issue of growing importance to auto consumers worldwide.

These are just a few examples of how stud welding is being applied at manufacturing sites around the globe. Today, manufacturers seek out expertise from precision engineering experts to design studs and fasteners that will bring notable benefits to their end products. These seemingly small changes in welding processes can have a tremendous impact on product innovation and safety, manufacturing quality, and bottom-line costs.
