Abstract

PURPOSE: To make the adjustment of welding conditions simple and stably weld base metals even if a wire is away from them by using a DC power source as a wire heating power source and inserting the welding wire in the position forward of the positive polarity TIG arc.
CONSTITUTION: While a welding wire 1 is being fed, a DC power source 12 for wire heating is closed. The positive polarity TIG arc 10 is fired and the wire 1 is inserted into this arc. If the wire 1 is in contact with a base metal 4, it is heated by current conduction and the arc deflects in the direction of the wire 1. The wire 1 melts and is cut by being enveloped by the deflected positive polarity TIG arc 10 and shifts onto the base metal 4. When the wire 1 is cut, the current supply from the DC power source 12 for wire heating stops, and the deflection of the positive polarity TIG are 10 also stops, thus resulting in decreased heat input to the wire 1. The wire 1 quickly passes the inside of the arc 10 and again short-circuits to the base metal 4, so that it is electroheated. After this, the arc 10 again deflects toward the wire 1, and the above-mentioned cycle is repeated.
