Claims

[Scope of Claim for Utility Model Registration] (1) Welding travel in which a trolley body that holds a welding torch is equipped with wheels and a motor, and the wheels are rotated by motor drive to move the welding torch along a welding line. 1. A welding truck, characterized in that the truck body is provided with support rollers that support the truck body, which is placed on the plate to be welded across the plate from the opposite side of the wheels, together with the wheels. (2) In a welding traveling trolley in which a trolley body that holds a welding torch is equipped with wheels and a motor, and the wheels are rotated by the motor drive to move the welding torch along a welding line, the trolley body has wheels and a motor. Support rollers are provided that support the main body of the truck, which is placed on the plate to be welded with the plate in between from the opposite side of the wheels, together with the wheels.An arm is also extended from the main body of the truck, and a welding torch is attached to this arm. What is claimed is: 1. A welding traveling trolley, characterized in that the welding trolley is held and is provided with a tracing roller for the welding torch on the tip side of the arm to cause the welding torch to trace the welding line.
