Frequency control of the drop detachment in the automatic GMAW process
A method was introduced for control of the detachment frequency in automatic GMAW process to achievemore regularity in drop detaching. The deposition area, heat input and voltage to current ratio were reg-ulated as the performance indicators...
Improving the dynamic metal transfer model of gas metal arc welding (GMAW) process
Abstract This work presents an improved model of characteristic equations for gas metal arc welding process. In this paper, a dynamic electrical model is introduced as a rectifier power source instead of pervious common ...
Influence of Converter and Inverter on Dynamic Behavior of the GMAW Process
This paper invest igates the dynamic behavior of Gas Metal Arc Welding (GMAW) process for two types of power supplies–inverter and rect ifier-for short circuit t ransfer mode. The large ripples on the rect ifier power source are able to perturb...
