Spot Welding
One method of welding is Spot Welding, also known as Resistance Spot Welding (RSW).Spot Welding does not require filler material, and instead works by using an electrical current to generate heat. This method of welding is best suited for materials with low thermal conductivity that will generate enough conductive metal to bond the metal together. Because of this, low carbon steel is one of the most suitable materials for Spot Welding. Spot Welding is best for high production volumes of parts.

Stud Welding
Stud Welding covers a range of welding techniques including Drawn Arc Stud Welding, Short Cycle Stud Welding, and Capacitor Discharge Stud Welding, which all produce strong welds. Stud Welding works by creating an electric arc between a fastener (stud) and the parent material. Stud Welding is a more flexible and economical choice than Spot Welding for a range of welding operations, and is also more versatile in the use of materials.
