摘要： A welding device for gas shielded arc welding includes: a portable welding robot mounted with a welding torch including a nozzle that guides jetting of shielding gas and a contact tip that performs energization on a consumable electrode; a feeding device that supplies the consumable electrode to the welding torch; a welding power source that supplies electric power to the consumable electrode via the contact tip; a gas supply source that supplies the shielding gas to be jetted from a nozzle end; and a control device that controls the portable welding robot. When the welding torch is seen from a side of jetting of the shielding gas, the contact tip is placed in an inside of an opening of the nozzle, the nozzle and the contact tip have a relatively movable structure, and an inner diameter of the nozzle end is within a range of 10-20 mm.

摘要： In this welding control method for a portable welding robot that moves along a guide rail, for using the portable welding robot to weld a workpiece including a groove: a groove shape detection position is established in at least one location in a welding sector extending from a welding starting point to a welding end point; the groove shape at a groove shape detection position Pn is sensed by means of a detecting means of the portable welding robot, which is moving along the guide rail; groove shape information is calculated from detection data obtained by the sensing; and a welding condition is acquired on the basis of the groove shape information.
