Resistance welding is a very popular process used in applications across a wide range of industry sectors, including white goods, automotive, heating and ventilation, aerospace and construction. Due to its high speed and reliability, resistance welding is particularly suited to mass production.
Spot welding, the most commonly used process, is primarily used to join metal sheet; the process can accommodate a wide range of materials and thicknesses (from 0.5 – 5.0mm). Materials that can be spot welded include: low carbon steels, high strength steels, press hardened steels, stainless steels, nickel alloys, aluminium alloys, titanium alloys, copper and its alloys, magnesium and some refractory metals.
AMPCOLOY® 972 (CuCrZr), AMPCOLOY® 95 or AMPCOLOY® 88 are used in the automotive industry and production of radiators for central house heating, as point welding caps, welding wheels for stainless-steel water sinks, etc… Another typical application is the resistance welding of concrete wire mesh with AMPCOLOY® 95 or AMPCOLOY® 88.
