Abstract
PURPOSE: To achieve the evenness of melting depth and the improvement in reproducibility in the captioned welding by applying alternating currents of the times more than the discontinuous shift times that an arc column naturally assumes for the arc current and giving spot-like poles evenly to the entire surface of the weld line.
CONSTITUTION: This method enhances directivity, evenly melts the entire part and obtains sufficient fusion-weld zone by defining the time lapse for the elongation and growth of the arc column to determine pitch is order to form the poles to spot-like uniform shape, area and pit, and applying instantaneous large current in order to form the spot-like poles surely. If an example is taken of the case when the high-frequency AC power source of the system combining a constant-current regulated AC power source and thyristor inverter is used, first the poles are surely formed in the minimum voltage position by the peak current which is applied instantaneously, by which an arc is generated and its area is increased with time. Since the polarity changes over at the high times of this time, the discontinuous shifting of the arc column is considerably defined, thus it becomes of a fixed pitch and area and is formed evenly over the entire surface.
