The Arplas technology is based on the principle of applying the minimum possible energy (heat) to the parts to be joined, while still reaching a full structural weld. It uses a distinctively different set of parameters (time, force and current) than traditional techniques. The release of a short time and high current pulse creates a structural weld, while the heat affected zone is significantly reduced.
The thermally induced stress relieve, well known from traditional techniques, is almost non-existing. This results in less deformation in the parts, leading to an excellent perceived quality combined with a reduced vehicle mass and better stability of the welded parts. These characteristics enable cost saving technical applications. Compared to traditional resistance welding techniques, the welds are almost invisible.
