Resistance welding is 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, the most commonly used process variant is resistance spot welding. Spot welding is primarily used to join metal sheet, the process can accommodate a wide range of materials and thicknesses, usually between 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.
