Abstract: The invention relates to a method for welding a holder (20) comprising a narrow surface, the holder (20) being joined to a metal sheet by means of said narrow surface. According to the inventive method, the narrow surface of the holder (20) is retained at a free distance from the metal sheet (24), a voltage is applied between the holder (20) and the metal sheet (24), and an electric arc (42) burns between the narrow surface and the metal sheet (24). Some material is removed from the narrow surface because of the electric arc and is applied to the metal sheet (24) as a deposited melt (46). The holder (20) is then brought in contact with the metal sheet (24), the narrow surface of the holder (20) being dipped into the deposited melt (46). The melt crawls up along the holder (20) and a concave welding seam or filling is formed. The voltage is switched off and the electric arc (42) is extinguished. The welding process is rendered more stable by using inert gas.

Abstract: A method of welding a stud (11) is provided. In another aspect of the present invention, a welding system is provided for a weld stud (11). A further aspect of the present invention employs a weld stud (11) with a substantially conical end section (29). Still another aspect of the present invention includes a welding method, wherein an aluminum or aluminum alloy stud (11) is brought into contact with an aluminum or aluminum alloy base material (14), voltage is applied between the stud (11) and the base material (14), the stud (11) is lifted slightly off the base material (14), an arc is generated, the tip of the stud (11) and the section of the base material (14) to be melted are melted, pressure is applied to the tip of the stud (11) and the section of the base material (14) that has been melted and the stud (11) and base material (14) are welded together, the current is divided into at least three stages and incrementally increased from the beginning to the end while the main arc is generated, and/or the molten tip of the aluminum or aluminum alloy stud (11) is applied under pressure to the molten base material (14) in under five milliseconds after the arc current has been cut off.

Abstract: A process and apparatus for welding a metal component (28) to a metal workpiece (40). The component (28) typically comprises a metal weld region (36) and a threaded connector region and the apparatus includes a weld head comprising a nozzle (8) for holding the weld region (36) of the component (28) adjacent the workpiece (40). The weld head induces a weld arc between the weld region (36) of the component (28) and the workpiece (40) to create a weld pool of molten material. The weld head subsequently moves the weld region into the weld pool to permanently join the component (28) to the workpiece (40). The apparatus further comprises a pressurised fluid source and a fluid flow control means for directing the pressurised fluid between the weld head and the component and weld pool so as to deflect any airborne fluid residue of the weld pool away from the connector region of the component (28).

Abstract: OBJECTIVE
To provide a 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 and also to provide a tool which has a simple structure and adapted to be used for said method.
STRUCTURE
An end of an operational 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 is comprised of 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.
