High-Performance System for Simultaneous Multielement Resistance Welding
The article presents initial results related to a newly developed system enabling the quasi-simultaneous welding of elements requiring high dimensional tolerances. The above-named system was developed in response to a new market demand for elements made in very short production cycles. A response to such a demand is an innovative solution including a digital system enabling the switching of welding current with a flexible frequency of even up to 10 kHz. The above-named solution makes it possible to control welding current in individual branches of equipment so that the welding power source is not able to notice a break in the welding process and all of the welds are formed at the same time with the precise definition of the current path.
