<p>PROBLEM TO BE SOLVED: To provide a welding method and a welding device using a robot capable of preventing an increase in equipment space and work man hour, and capable of effectively preventing sputter from being adhered to a hole provided on a workpiece during welding.SOLUTION: A sealing member 30 attracted and held on a holding member 40 by a magnet is inserted into a hole such as a screw hole provided on a workpiece by the movement of an arm 11 before welding with a welding torch 20, and thereby the hole is sealed. Then, by the movement of the arm 11, the holding member 40 is moved in a direction vertical to the central axis of the hole and opposite to the sealing member 30, and thereby the sealing member 30 is separated from the holding member 40 and is left inside the hole.</p> |
