Calculation of the Heat Content of the Electrode Metal Droplet When Applying Power Supplies for Manual Arc Welding with Different Volt-Ampere Characteristic

Abstract: In the paper the authors provide the method for calculating the heat content of the molten electrode metal droplets according to the energy parameters of the power supplies for manual metal arc welding. It was established that the type of the welding power supply has a significant impact upon the temperature, mass and active surface area of the electrode droplets.

“…Evidentemente, cuando se trata de electrodos con un mismo tipo de núcleo, la única diferencia se deberá al tipo de revestimiento empleado en su confección [1]. En este caso, el tipo de revestimiento determinará las características de operación de cada electrodo, por lo que es importante conocer esas diferencias [2].…”

“…Intergranular corrosion (IGC) can be reduced if welding energy parameters are controlled by applying a high-frequency pulses [10], transition of droplets into the molten pool is regulated using a pulsed wire feed [11], inverter power sources are applied [12], the weld pool is protected with gas [13]. Welds will have a high resistance to hot cracking and intergranular corrosion if the weld metal has a two-phase austenitic-ferrite structure.…”
