Using artificial neural networks to identify and optimise the key parameters affecting geometry of a GMAW fillet weld [PDF]
, 2015 Control of Gas Metal Arc Welding (GMAW) parameters is key to maintaining good quality and consistent fillet weld geometry. The external geometry of the fillet weld can be easily measured, however the internal geometry (i.e.

Investigations of GMAW plasma by optical emission spectroscopy
Plasma Sources Science and Technology, 2007 We report on investigations of gas metal arc welding plasma operated in pure argon and in a mixture of argon and CO2 at a dc current of 326?A. The spatially resolved electron densities and temperatures were directly obtained by measuring the Stark widths of the Ar?I 695.5?nm and Fe?I 538.3?nm spectral lines.Our experimental results show a reduction of ...
