What is Resistance Welding?
Resistance welding joins two work-pieces without the need for extra material. Using resistance welding in your process is more cost effective than other types of welding. There are a variety of resistance welding options to produce the weld nugget needed:
- Spot Welding – uses the face geometry of the welding electrodes at a desired weld location.
- Seam Welding – employs a wheel-shaped electrodes where the work-piece rolls, the welds are either overlapping to make a complete seam or have a defined spacing.
- Projection Welding – uses projections, embossments, or intersections to focus heat to a point.
- Flash Welding – is accomplished through applying high current density at a small point to connect two pieces.
