In
this study, Aluminium 5754-7075 plates in 2.0 mm thickness were joined by
magnesium-based (AlMg5) wire in cold metal transfer (CMT) technique. The
specimens were prepared in butt joint form. Argon was used as shielding gas and
joining operations were done with 20o working angle. Joining operations were
done with four different gas pressures as 10, 12 14, 16 l/min. After that,
tensile properties of joints were determined and macro-structures of joints
were investigated in order to see the joinability of aluminium 5754-7075 alloy
by CMT (cold metal transfer) technique. Finally, the micro-hardness values of
specimens were measured.
