Applications and benefits of adaptive pulsed GMAW
Mechanics, 2014 The aim of this study was to investigate adaptive pulsed GMAW processes, considering possible benefits when welding thicker sections (> 3 mm) and structural steel. Adaptive pulsed GMAW processes are adaptive in that electrode feed speed is automatically adjusted and corrected to the mean pulsed current or voltage variation.
