Abstract
Disclosed is an orbital welding system for welding the joints of tubes of tube plates of heat exchangers, including: a programmer generator; an orbital welding head; and a first supply line of an inert gas for TIG welding. The orbital welding head includes: a welding torch; a stopping system for the torch against a tube plate; an expandable centring tool for fixing the orbital welding head at one of the tubes; an actuator for the centring tool; and a second supply line for a pressurized gas to operate the actuator. In the orbital welding system, the second supply line for a pressurized gas is branched off at a point from the first supply line and carries the same inert gas.
