Friction Stir Welding of Mg and Al Alloys

Abstract:

The work deals with welding of aluminium alloy typeAlMg4,5Mn and magnesium alloy type AZ 31 in solid state by FSW (Friction Stir Welding) process. Experiments were performed in cooperation with VÚZ PI SR (Welding Research Institute Industrial Institute of Slovak Republic) Bratislava, which has available a new installed equipment type FSW LM 060 manufactured in China. Welding parameters and conditions were proposed and approved. Quality of fabricated joints was assessed by optical microscopy, micro hardness measurement and radiographic test - RT. It was supposed that optimisation of welding parameters would allow to fabricate the joints of acceptable quality that might compete to technologies of fusion welding, including welding with concentrated power sources.
