Flexweld®
Resistance element welding
of a car‘s total weight
is in the body
The considerable reduction in weight is one of the great strengths of the Flexweld® joining system. So it is a key element in moving car production towards more lightweight construction.
Flexweld®
The joining process in detail
Flexweld® elements are selfpunched and embedded into the aluminium sheet. This sheet is then welded to steel components, using conventional resistance spot welding guns, and then bonded with adhesive.
