Welding metal parts in R&S Radev & Sons, Bulgaria
Welding of metal details
Welding processes
Welding is a process in which monolithic metal products are obtained from several elements. Radev & Sons Ltd. offers you welding of ferrous and non-ferrous metals performed by highly qualified welders under various methods. In the case of MIG/MAG arc welding in protective environment with melting electrode wire, we use inverter tools operating in “pulse” and “double pulse” mode. Where spot welding is carried out through heating and melting at the point of contact and by the application of mechanical pressure, we use an electric resistance welding machine with pneumatic drive.
