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. This process can be controlled to produce individual spot welds, or in a line (Seam Welding).
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. Huys has over thirty-five years’ experience in resistance spot welding (RSW) and has developed effective solutions to these challenges with the help of SORPAS. These include our patented or patent pending TiCaps™, and Taper Tools™.
Huys employees serve on committees of the American Welding Society (AWS), Standards Council of Canada (SCC) as well as ISO committees for RSW. Huys has numerous patents and patents pending for advances in RSW and related technologies.
