On the Activation Energy of Weld Metals

Abstract

"Activation energy" may be observed as a procedure of testing weld metals to guess from the numerical magnitude of that energy whether the weld metal is stable or unstable with regard to the atomic arrangement.
This procedure will also help in deciding proper uses of several types of electrodes according to their characteristics.
"Activation energy" observation should be carried out to the same extent as various other mechanical tests, especially in the case of a weld metal in which high temperature was used.
