Abstract
A command and control device (1) for a coupling-welding machine (2) for metal pipes (3, 4) within which said machine is positioned, said machine (2) being movable within the pipe by drive means (5) and provided with welding means (6) for joining different pieces (3, 4) of said pipe together, the operation of said welding means (6) and drive means (5) being controlled by control means (12) associated with the machine (2) and connected to commanding means (9) external to the pipe. The operation of the machine (2) is controlled by a single microprocessor unit associated with the control means (12).
Claims11
A command and control device for a coupling-welding machine (2) for metal pipes (3, 4) within which said machine is positioned, said machine (2) being movable within the pipe and provided with welding means (6) for joining different pieces (3, 4) of said pipe together, and comprising drive means (5) enabling it to move independently within the pipe, the operation of said welding means (6) and drive means (5) being controlled by control means (12) associated with the machine (2), said control means (12) being connected to commanding means (9) which are external to the pipe and which actuate the operation of the welding means (6) and drive means (5), the machine (2) being provided with an energy source (13) which can be powered from the exterior of the pipe by charging means (14) connected to said source (13) via a corresponding power line (16), said device being characterised by comprising only a single microprocessor unit for controlling and actuating the operation of the coupling-welding machine (2).
