Estimation of Process Stability in the MAG Welding Process by Monitoring the Welding Parameters



Thomas A. Siewert


This paper presents the distribution of the main welding parameters (welding voltage and welding current) for semiautomatic arc welding with the metal active gas (MAG) process, using both flux- cored and solid electrodes. Two different shielding fases were used: pure CO2 and (82% Ar + 18% CO2). Welding parameters were recorded by an on-line welding parameter monitoring system. Besides reporting the distribution of the welding parameters, this paper presents some results of off-line analyses (such as spectral analysis, mean values, range, and standard deviations). from this data, we were able to estimate the stability of the welding parameters. Comparison of the stability data for different components permits the selection of optimal power sources, welding parameters, filler material, shielding gas, etc.
