Main Article Content
Abstract
Artykuł dotyczy technologicznych aspektów łączenia stopów magnezu z grupy AM metodą MIG z zastosowaniem materiału dodatkowego z grupy AZ. W ramach pracy wykonano złącza doczołowe płaskowników o grubości 3 mm wykonanych z odlewniczego stopu magnezu AM50 z zastosowaniem drutu elektrodowego o średnicy 1,2 mm wykonanego ze stopu AZ31. Złącza wykonano przy różnych wartościach natężenia prądu spawania. Jakość złączy oceniano na podstawie badań wizualnych i badań mikroskopowych.
Welding of magnesium alloy from AM group by MiG method
Abstract
The paper presents results of joining magnesium alloys from AM group by MIG method with the use of filler material from AZ group of magnesium alloys. Welding tests were carried out making butt joints of 3 mm thick plates of casting alloy AM50 using AZ31 alloy electrode wire of diameter 1.2 mm and argon as the shielding gas. The quality of obtained joints were assessed on the basis of visual inspection and macrostructure examination. Additionally the SEM measurement of main elements distribution in welds also done.
