Two electrode welding with different currents supplied to the electrodes |
摘要 |
In a two electrode welding method wherein welding is carried out by means of arcs struck between two electrodes and a parent metal, the two electrodes being located in side-by-side, spaced-apart relation in a direction in which the welding surface advances and movable relative to the parent metal, a portion of the parent metal is preheated by the arc struck between the leading electrode and the parent metal, and a preheated portion is melted by the heat of the arc struck between the trailing electrode and the parent metal when the former has moved to a position above the preheated portion of the latter to provide a deposited metal. The method has particular utility in applications where metal of high heat conductivity, such as copper, is welded.
