Resistance spot welding is a process where heat from electrical resistance is used with force and time to weld metallic materials. The concentration of pressure and electricity in a small “spot” causes the two sheets of metal directly between the caps (seen above) to melt into a molten state. Once cooled, these sheets have been “spot” welded together.Resistance welding’s primary use is in the manufacture of automobiles, where the average car has some 5,000 spot welds. The rise of coated steels, high strength steels, and most recently hot stamped steels and aluminum in the automotive industry have presented challenges to this simple but effective joining method.

RWMA Class 11:Copper Tungsten (75%W 25 %Cu)
RWMA Class 12:Copper-Tungsten (78%W 22 %Cu) & (80%W 20 %Cu)
RWMA Class 13:Pure Tungsten (100% W)
RWMA Class 14 :Pure Molybdenum 100%
RWMA Class 20: RWMA Class 20
COPPER-ALUMINUM OXIDE has exceptional resistance to deformation when welding and is highly recommended for weld caps when welding coated
and galvanized steels. It allows a stable start-up and generally outlasts other cap material when welding parameters are not carefully controlled.
Refractory bi-metal composite produced by a tightly controlled process of pressing and sintering tungsten powder and infiltrating the sintered material with silver.
Grade A50WS ( Tungsten Silver 50/50)
Grade A35WS (Tungsten Silver 65/35)
Grade A20WS (Tungsten Silver 78/22)
Electrode cap tips are made from class1, class2, Zirconium-Copper, Chrome-zirconium-copper and dispersion strengthen copper.
