• Transfer Mechanism of Multi-Arc in Welding

抄録

The melti-arc has been so widely used in welding, but it is not. evident how the arc can transfer from one electrode to another.<BR>Authors have deeply studied the after-arc phenomener, and applied our theory to the clarification of the transfer mechanism of the multi-arcs.<BR>We will report our results as we have acquired its clear solution.<BR>In our method, we measured separately the currents flow through the two electrodes.<BR>In addition, we used an interrupter in a circuit of a current in order to lead the transition of in our accords.<BR>We investigated the variations to time of the currents, voltage and arc-resistance at the vicinity of the transition.<BR>Our results and considerations lead to the following conclusions ;<BR>a) The transition happens when the arc resistance becomes a certain constant value.<BR>b) The interval of the transition is about 1/100 sec.<BR>c) The reparate currents flow at the interval of the transition, but the essential arc seems to have already transfered.<BR>d) Strictly speaking, the arc voltage should go down slowly. and not abruptly.<BR>e) In general, the abrupt increase in the arc voltage by some reasons (for example, the dsecend of globuls except the transition induces the transition.<BR>f) The number of the abnomal increases in the voltage are larger than the numbers of the transitions.<BR>g) When we induce the. transition by the interrupter, the arc voltage decreases without fail.
