[ 1 ] - Influence of Converter and inverter on dynamic behavior of the GMAW process

This paper investigates the dynamic behavior of Gas Metal Arc Welding (GMAW) process for two types of power supplies –inverter and rectifier- for short circuit transfer mode. The large ripples on the rectifier power source are able to perturb the metal transfer mode. In this experimental work some operating points in the short circuit mode have been selected using an automatic pipeline welding ...
