Abstract

PURPOSE:To enable the temp. control of a molten pool and the shape change thereof, by supplying a large-diameter cold wire to the molten pool formed by feeding electricity to a small-diameter welding wire fed in a welding tip and generating an arc between said wire and the work. CONSTITUTION:The work 3 is welded while the forward end part of a cold wire 5 having a large diameter is disposed in a molten pool 4 formed on the work by generating an arc between a welding wire 2 of a small diameter fed in a tip 1 and the work 3. The rate of melting of the wire 5 is controlled and the temp. of the pool 4 is controlled, whereby the viscosity of the pool 4 is controlled. The position where the wire 5 is disposed in the pool 4 is adequately changed to increase the amt. of the deposited metal in the disposed position whereby the shape of the pool 4 is changed.

Since the amount of heat input to the consumable welding wire is determined by the output box of It is determined that the amount of metal in the droplet is 7 and cannot be controlled.
In order to increase the intensity of the illumination, it is possible to use a device that has an output of 1 V (1) and is capable of supplying a pulse-like force to the wire. However, the drawback is that it is expensive.
