چکیده مقاله
In this study, fast welding of aluminum for marking on hot steel ingots was investigated Connection process on 6 samples with different voltage, wire feeding speed and preheating temperature by gas metal arc welding method with argon shielding gas and filler metal 5356 to investigate the effect of heat input and preheating temperature on the microstructure and mechanical properties of the connection The results showed that with increasing the heat input, the microstructure of the weld metal changed from columnar dendritic to coaxial dendrites, also increasing the probability of intermetallic compounds formation and increasing residual stress According to the microstructural studies and mechanical properties, it can be concluded that having a suitable heat input 6 83 J / mm has caused the columnar dendritic microstructure and coaxial dendrites The microstructure of the columnar dendrites was optimally sampled so that the dendrites extended perpendicular to the joint, reducing the anisotropic properties of the mechanical properties that are appropriate
