Introduction to resistance spot welding

Resistance Spot Welding is one of the oldest of the electric welding processes in use by industry today. Major advantages of spot welding include high operating speeds and suitability for automation or robotization and inclusion in high-production assembly lines together with other fabricating operations. Defining resistance spot welding: RESISTANCE SPOT WELDING (RSW) is a process […]

Narrow gap welding processes

The single filler wires used most commonly have diameters in the range 3.2–4.8 mm; smaller wires are prone to cause random arc wander, particularly with the relatively long electrical stick-outs that are used, and larger diameter wires are more difficult to feed. welding processes Although it is possible to use standard fluxes, special flux formulations with […]
