Low electric D.C., low time rate polarity reversing arc welding method |
摘要 |
Direct electric current arc welding between an electrode and a workpiece surface is accomplished in the electric current range of about 0.5-45 amps while reversing the polarities between the electrode and the workpiece surface at a low frequency rate in the range of about 1-1000 cycles per second, in a series of polarity cycles. The workpiece surface, in at least some of the cycles, is positive for a time less than that surface is negative to result in anodic cleaning of the workpiece surface. If the arc is extinguished during a polarity reversal, the arc is maintained, for example, by restriking.
