Robotic Aluminium Spot Welding

Several different types of alloys are used in Automotive, mainly from the 5xxx and 6xxx series. Depending on the applications, they can take the form of sheets, mould castings or extruded strips. They can be used in most parts of bodies, opening elements and battery casings. Various thicknesses and grades can be combined, with or without adhesive, whose use is fast growing to enhance the rigidity of assemblies. Then, in most cases weld is combined with structiral adhesive bonding.

A strong welding current is necessary to weld Aluminium almloys due to their high levels of electrical conductivity, but the welding time is very short (60 to 200 ms). The use of force profile ensure the best weld quality (force increase during squezze and forging).
