抄録

The flashing current waveforms have been discussed using the steel sheets in Part 1.<BR>In Part 2, all the flashing operations were performed using the constant rates of platen acceleration same as Part 1. The microcomputer was used to calculate the secondary current and comsumed power during flashing. The following results are obtained.<BR>1. In the latter flashing operation, the flashing current amount to a constant value and decreases with the increasing of the secondary no load voltage, but the electric power is not affected by them.<BR>2. In regard to the mechanical properties of welded joints, the factors in bridge phase, such as peak or effective current and power, have the positive coefficient of correlation, and those in flash phase have the negative one.<BR>3. It was found that the decreasing of secondary no load voltage increases the values of current and power in brigde phase, and also improves the quality of the welds due to the increasing of absorbed thermal energy in the material to be welded.
