ABSTRACT:
The invention provides a tool and method for repairing a sheet metal according which a dented portion of a sheet metal can be easily and appropriately pulled out with a minimal force. The tool has a simple structure and adapted to be used in the method. The tool includes an end of an operation shaft 1 having a given length serves as a handle portion 2, and an arc electrode 3 is affixed to the other end. A support stand 4 is attached to an end of the operational shaft 1. The support stand 4 may include a base 5 through which the operational shaft 1 is inserted and affixed thereto, a leg portion 6 extended from the base 5, and a seat portion 7 attached to the lower end of the leg portion 6. With the configuration as above, the arc electrode 3 is welded to a dented portion r of a sheet metal while the seat portion 7 is in contact with the sheet metal surface R, and the operation shaft 1 is tilted in that state, while the seat portion 7 is pressed against the sheet metal surface R. Thus, the dented portion r joined to the arc electrode 3 is pulled out by leverage.
