Abstract

PURPOSE:To automatically make an electrode copy to a welding line, by controlling a torch position based on a welding current, an electrode delivery speed, a welding voltage and an oscillation position, in a gas shield wear electrode type arc welding oscillating the torch. CONSTITUTION:A speed (v) of a wire 6 fed to a torch 1, a voltage V between a tip 3 and an object 12 to be welded, a welding current I and instantaneous position of an oscillator 11 are respectively detected at detectors 22, 25, 27 and 29. They are A/D-converted and inputted to an electronic computer 24 where a distance LD between the tip and the welded object to be kept constant is set. Tip and welded object distance Ex+L is obtained from the (v), V and I, this is compared with the LD, power supplies 34 and 36 are controlled to drive up/down and left/right transfer devices 15 and 17. On the other hand, in oscillating the torch with an angle + or -theta, when Equation I is zero at theta=0, the torch position is controlled so that Equation I is zero, and when not 0, the torch position is regulated with the devices 15 and 17 until the shift angle of a point for the maximum value of the Ex+L from the center is zero.
