<p>PURPOSE:To easily weld a joint part of piping without allowing an operating to enter the connecting part of a digged groove. CONSTITUTION:Caterpillars of a traveling carriage 2 are arranged on the ground at both sides of the digged groove. In a state with a welding robot 6 and a pipe fixing robot 7 mounted on the upper part of the traveling carriage 2, the caterpillars on the and the traveling carriage 2 is made to travel along the cut and covered groove. When the traveling carriage 2 reaches a weld zone of piping and stops, small carriages 4 and 5 are made to travel along a rail 3 provided on the traveling carriage 2 and the welding robot 6 and the pipe fixing robot 7 are moved to the lower part of the traveling carriage 2. Newly provided piping 21a is clamped by the pipe fixing robot 7 and welding-all-around of the joint part 26 between an existing piping 21b and a new construction piping 21a is performed by the welding robot 6.</p> |
