Abstract
Using the calculated result of the ratio R of transient temperature rise to the quasi-stationary state temperature in a thin plate due to a moving point heat source, some considerations on the transient temperature variation of the points near arc starting or stopping in the mother plate are made.According to literature (1) the transient temperature of any point on the circle whose center is the present arc position and whose radius is equal to the distance of arc travel from the starting point, is just half the quasistationary state value. It is remarkable that the above mentioned relation holds true independently of thermal constant k and arc traveling velocity.Tables 1, 2 show some calculated results.
