A Proposal to Easily Find Out on Arc Stability of Welding Electrode

A Study on Working Characteristics of Welding Electrode

Abstract

We recommend a convenient and easy way to judge or compare with propriety of arcing condition of coated arc welding electrode by using of critical arc length-maximum length of arc condition between base plate and electrode.
Because, the statistical enough correlation could be found between the critical arc length measured and the sensuous evaluated marks of arc stability by many test welding operators. And the reproducibility of the critical arc length was enough obtained to be able to compare with these many coated type of electrodes marketed, practically, each other.
