Resistance spot welding

We create solid welded joints between the two materials, using the resistance spot welding machines with high pressure on small surface and high electric energy. The most important parameters in the resistance spot welding are the electric current, the resistance, the heat and pressure. In the resistance spot welding, both welding electrodes push the components towards each other. Subsequently, the machine turns on the welding to induce a contact resistance. This leads to thermoelectric heat, resulting in melt. The electrical current is turned off, the liquid material hardens and the welded joint is solid. When cooling the melt, pressure must be maintained to avoid the pores. We use the facilities with different parameters for resistance spot welding of wide-range materials. The thickness as well as the product shape complexity play a role in selecting individual machines. A variety of facilities, such as the model DALEX PL63 OHK, made by BEZ Bratislava BN 20.12, or the model DANUBIUS BP 90.22 meet demanding criteria and requirements for the resistance spot welding.

DALEX PL63 OHK

The DALEX PL63 OHK is a parallel stroke spot welding machine with closed circuit and water-cooling unit and electronically controlled cooling fluid Cool 2.  It is an extremely stable and durable machine that meets the criteria for modern spot welding. 

It features high-performance pneumatic drive and water-cooled, layered high-power transformer suitable for high-performance and long duty cycle. The parallel guided electrode force enables to achieve the maximum pressure force easily. The infinitely adjustable throat depth and arm distance allow even welding of complexly-shaped part. Offering comfortable memory function for up to 8 material and component pairings, the machine provides multifunction welding control. 

The circulating water-cooling system ensures operations with no technical and thermal problems even in shift operation.
