Opis:: In this study, Aluminium 6082-T6 plates having 1.0 mm thickness were joined by magnesium-based (AlMg5) wire in cold metal transfer technique. The specimens were prepared in butt joint form. Argon was used as shielding gas and joining operations were done at gas flow speed of 13 l/min. The joining operations were carried out during four different working times of 25, 30, 35, 40 and 45 seconds. Tensile properties of joints were determined and macro-structures of joints were investigated in order to evaluate the joinability of Aluminium 6082-T6 alloy by cold metal transfer technique. Finally, the micro-hardness values of specimens were measured.

Opis:: In this study, DP 600 (Dual-Phase) steel plates having 1 mm thickness were joined by copper-based CuAl8 wire in gas metal arc brazing technique. Specimens were prepared as butt joint. Brazing operations were done with ten different arc voltages and weld currents as 40, 45, 50, 55, 60, 65, 70, 75, 80 and 85 A. Tensile strength, bending force, microstructure of brazed materials, and their microhardness distribution throughout joining were determined. In macro and microstructure examinations, stereo optical microscope, scanning electron microscope (SEM) and energy dispersive spectroscopy were used. This study investigated the effects of current intensity on microstructure and microhardness distribution of transition zone between DP 600 steel and MIG-brazed joint. The tensile strength and bending resistance increase with increasing current intensity.

Opis:: In this study, TRIP 800 (Transformation Induced Plasticity) steel plates, 1.5 mm in thickness, were joined with copper-based (CuAl8) wire by the gas metal arc brazing technique. Specimens were prepared in butt joint form. Five different working angles 50° , 60° , 70° , 80° and 90° were selected for brazing operations. A copper based CuAl8 wire was used as the filler metal. After the metal inert gas brazing process, butt joined specimens were exposed to tensile test in order to characterize the mechanical properties. The microstructure of the joints was investigated by scanning electron microscope (SEM) and optical microscope to see the joinability of TRIP 800 steel by gas metal arc brazing technique.
