Submerged Arc Tank Corner and Fillet Welding Tractor for Oil Storage Tank

The tractor are mobile units can be easily transported to any workstation and adapted to fillet seam and flat seam. The modular design of the tractor make it easier to extend the units with additional devices, i.e. flux supply unit and flux recovery unit. Suitable components can be combined in an optimum way for every welding process.
