Abstract
PURPOSE: To form the sound weld zone free from any undercut without using any ancillary facilities such as for weaving by adjusting the torch set positions according to the fluctuations in groove gap width and balancing the feed rates and melting amounts electrode wires in performing narrow groove butt are welding of plates.
CONSTITUTION: Electrode wires 1 are fed at the same speed by a motor 2 and are let to reach a conductive chip 4 through the hole of a flat-plate form torch 3. Current is supplied from a DC constant voltage power source 5 and further the wires are passed through the ceramics guide 6 provided with two holes directing separate corner parts. Here, arcs 7 are put in the position of a distance of about 1/5 the groove width from groove side walls 8. When the groove width fluctuates along with progression of welding, the welding torch 3 is vertically moved with an elevation control motor 12, by which the positions of the electrode wires 1 are controlled according to the fluctuations of the groove gap width. The rotating speed of the electrode wire feed motor 2 is controlled and the current is made constant, whereby the amount of the molten metal 13 right under the arc 7 is controlled nearly to a correct amount irrespective of the fluctuations of the groove gap width and welding is done.
