- Abstract
It is a well known fact that introduction of exothermic mixtures in electrode coating composition can increase efficiency of manual arc welding. At that, distribution of heat between electrode and workpiece is not enough studied. This work studies thermal characteristics of heating and melting of the electrodes with different content of exothermic mixture in the coating. It is shown that introduction of the mixture in amount to 53.4 wt.% results in rise of coefficient of core melting from 8.7 to 11.6 g/(A·h), weld deposition coefficient from 8.1 to 13 g/(A·h) as well as growth of efficiency of base metal heating. 10 Ref., 2 Tables. 1 Figure.
