Over the years the Arplas System (AL-S)® has proven a reliable and quality enhancing Technology in various Applications in the automotive industry. Ever since the introduction of this Technology in 1997 it has been operated successfully in over 20 plants worldwide.
The basic principle of the AL-S® Technology is to apply the minimum possible energy to the parts to be welded while still reaching a full structural weld. The technology is based on the resistance welding principle but uses a completely different set of parameters than the traditional technique.
Resulting from its short weld-time (in fact about 4 milliseconds) and high current pulse, the heat influenced zone is importantly reduced. The thermally induced stress relieve, well known from traditional techniques, is almost non existing resulting in less deformation of the parts.
To focus the AL-S® Energy Pulse, an AL-S® Dimple must be formed in one of the parts to be welded together. By its special shape and sharpness, it is designed to guarantee structural welds between the parts, while leaving the non dimpled part blemish free. As the welding process takes places in only 4 milliseconds, keeping the weld force constant during the formation of the weld, requires the use of the AL-S® Head that is constructed to guarantee a fast follow up. Furthermore the dedicated low inductance AL-S® Transformer is designed to allow the current to reach its peak value within this time frame. Finally the AL-S Quality Certification System® is used to set parameters, measure the Current and verify and document the weld that is produced by The Arplas System AL-S®
