Abstract
1,267,820. Scarfing. AGA AB. 3 April, 1969 [16 May, 1968], No. 17474/69. Heading B3V. The gas scarfing of a workpiece 6 is initiated by moving, during the relative movement between the workpiece and a scarfing nozzle 7, a consumable electrode 3 towards the workpieee to form a molten pool on the workpiece surface, which pool has a sufficiently high temperature to be ignited by the scarfing oxygen. Just before a defect 8 is reached by the scarfing nozzle 7, the start button of the machine is actuated to cause the electrode 3 to be fed into contact with the workpiece immediately in front of the defect 8. Simultaneously an electric current is supplied to the electrode 3 and an electrode holder 1 pivoted about a pivot 2 towards a vertical position at a speed proportional to the relative velocity between the scarfing nozzle 7 and workpiece. A pool of molten metal is thereby formed on the workpiece surface. When the holder 1 has reached the vertical position, the electrode feed is stopped, the scarfing oxygen stream is initiated and the holder 1 rapidly returned to its initial position. The workpiece is preheated by heating flames 9. The machine may include a plurality of gas burners 7 having corresponding electrodes 3. Suitable electrical control circuits are disclosed (Figs. 2 and 3, not shown).
