Technology Of MIG-MAG Welds Strength Enhancement

Abstract: Abstract.A new technology of MIG MAG welding control is developed. Authors introduce use of power AC and pulse feed of welding wire in the arc zone, that downsizes the heat affected zone, stabilizes formation of electrode metal droplets, as external magnetic field's effect on the arc is reduced. Principal criteria for electrode metal transfer control, when powered by AC sources, are specified. IntroductionConditions of the arc, if power AC supply, differ from conditions of the arc, if DC power supply. The acti… Show more
