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.

Danubius BP 90.22

The Danubius BP 90.22 Spot Welding Press is characterized by a larger stretch of welding electrodes. It is primarily used for production of spot welded joints located farther from the sheet metal weldment edges. The spot welding machine has the ULB 4.4 control, which measures the welding current and regulates its inaccuracies. The control system reports an error when the weld is incorrect and it records the welding data on the MICRO SD card. 

The machine is equipped with pneumatic electrode downforce. The FESTO proportional vent with the pressure control ensures optimum electrode pressure throughout the welding cycle. What is more, you can adjust the pressure in each program individually with no need for operator’s adjustment, which increases the working efficiency. Water cooling system for electrodes contributes to the operation stability as well.
