Abstract
The suitable welding current varies not only according to kind of electrodes, but also size of plates and skill of welding operatiors. In this report, the author could confirm that the ranges of suitable currents for welding electrodes made by the Fukuchiyama Welding Electrode Works were considerlably wide.
In his opinion, using higher welding current in the allowable range is better than using lower current, for it will be con4ucive to the removal of slag inclusion and the improvement of mechanical properties of weld.
