    摘要： The welding equipment according to the present invention divides the pulsed electric current fed to a base metal in the course of a welding process into a plural number of pulse groups, performing instantaneous control over the base electric current period and the base electric current value applied to each of the pulse intervals of the individual pulses within such a group of pulsed electric currents and to each of the groups of pulsed electric currents, the pulse peak value and pulse width of each pulse, and such instantaneous control over a short circuit period and an arc period in the course of performance of the short circuiting transfer arc welding process, in accordance with the detected arc length, in such a manner that an ideal target arc length is thereby achieved. The welding equipment is capable of achieving the separation and transfer of molten globules to the base metal with regularity and also reducing the fluctuations in the short circuit period and the arc period in the short circuiting transfer arc welding process, offering the advantage that the equipment can control the growth and separation of molten globules without being affected by the phenomenon of magnetic arc blow of the arc and can achieve improvements on the quality of weldments even if fluctuations should occur in the shape of welded joints and in the position of the earthing point in operation with the actual arc.

In sort-circuiting arc welding, the short-circuit and arc are instantly controlled in accordance with the detected arc length or wire-supplying speed. This ensures the separation of the molten droplet and its transfer onto the base metal in regular manner. As a result, the growth and separation of molten droplet is not affected by magnetic blow of arc but is controllable.

The wire-supplying speed at which the wire is supplied to the weld zone changes. This causes undercut, i.e., a defect in welding bead-shape that presents adverse effect to welding quality. To prevent this problem, pulse current supplied to the base metal is divided into a plurality of pulse groups and the average current reaches the maximum peak value at a predetermined time after beginning of outputting the pulses, and the group of pulse currents is of a hill-shape in its envelope in accordance with the separation phenomenon of molten droplet, and the group of pulse currents is arranged to have different pulse period, pulse width, and pulse interval. In the sort-circuiting arc welding, the short-circuit and arc are instantly controlled in accordance with the detected arc length or wire-supplying speed.
