Evaluation of Modern Power Source for GMAW Welding Equipped with Advanced Arc Control

Popis výsledku v původním jazyce

Modern welding power sources are equipped with special functions of arc control. These functions measure and adjust welding parameters during welding with minimum time delay so that the right parameters are set. At the Laboratory of welding technologiesof CTU in Prague we have used modern welding source by Migatronic - Sigma Galaxy equipped with functions Intelligent Arc Control and Sequence Repeat. According to manufacturer these functions significantly improve welding process by stabilizing arc. Thisleads to lower heat input, deformation and improves weld quality. Single V butt welds were done on S275J2 of 10 mm thickness (2 weld layers: root + capping layer) in PF and PG positions. Also we have welded thin sheets with uneven root gap in PG position. Welding current, voltage was monitored by Welding Information System and compared with standard short arc GMAW welding. Results have shown that these "intelligent" functions offer significant advantages for welding of steels, especiall
