Abstract

The use of Gas Tungsten Arc (GTA) and Electron beam (EB) welding for investigating the weldability of cast magnesium alloys was discussed. The microstructural changes during welding were studied using optical microscopy. GTA welding of magnesium alloys created a large heat affected zone (HAZ), which surrounded the fusion zone (FZ). The coring effect during solidification of the cast ingot caused the source of the grain boundary embrittlement. Due to the thermo-mechanical properties of the rolling process, a smaller HAZ was found in welded Mg alloys.
