Circumferential welding machines​ (circular welding machines) are used for series production circular welding, such as joining pipes (boilers, fire extinguishers, air tanks, pressure vessels…). The welding process is automated with NC control, precise torch movement, and parameter control with a simple touch screen user interface. Once the welding piece is in place, all operations are performed automatically, including positioning, clamping, and welding. Specially designed tools can be used as needed. Digital welding parameters allow precise configuration of the machine before welding.
