Özet

The goal of this study was to investigate the weldability of aluminum by using the oxy-hydrogen welding technique. Specimen dimensions were 1.5 mm in thickness and 80 mm in length. Microstructural investigations on the cross-sectional area of the weld zone were also carried out in order to compare weld metal and HAZ depending on the welding gases. Tensile strength and microhardness tests were carried out and the results were compared. Test results have shown that the yield strength of the samples welded with oxy-acetylene is higher than that of the samples welded with oxy-hydrogen.
