On the Fundamental Study of the Multiple Electrode Submerged Arc Welding (Report 1)

Abstract

To speed up the automatic welding, we used the two welders, multiple power connecting process and parallel connecting process. In this welding, the effects of many factors, the distanc of electrode, welding current, speed, voltage, and angle and dimension of groove were investigated. As the result it is found that the multiple power connection process is the most valuable one which obtains the high speed of the welding and it also confirms the mechanical superiority of the weld metal.
