In this research, the effects of both current and argon gas pressure on the bending properties of welded joints were studied. Using the possible ranges of welding gas pressures and currents, Tungsten inert gas welding (TIG) of stainless steel (304) sheet was used to obtain their influence on the maximum bending force of the (TIG) welded joints. Design of experiment (DOE) ‘version 10' was used to determine the design matrix of experiments depending on the used levels of the input factors. Response surface methodology (RSM) technique was used to obtain an empirical mathematical model for the maximum bending force as a function of welding parameters (Current and Argon gas pressure). Also, the analysis of variance (ANOVA) was used to verify the adequacy of the resulted model statistically.

6061 Aluminium Alloy

An extensively studied Al-Mg-Si (AA6061) alloy has been considered for this investigation. This alloy is used for large number of industrial applications since it possesses medium to high strength to weight ratio, excellent weldability and corrosion resistance. It has been observed that these alloys are usually used in sheet form and were welded for large application. Even though a number of welding procedures are available, the most convenient and economical procedure of tungsten inert gas (TIG) welding was used to weld Al-Mg-Si sheets. All the sheets were having a thickness of 3.0 mm. In the case of single pass TIG welded samples, the pulsed current has been found beneficial as it is most advantageous over the conventional continuous current process. The use of pulsed current parameters has been found to improve the mechanical properties of the welds compared to those of continuous current welds of this alloy. This is possibly due to the grain refinement occurring in the fusion zone. These results clearly demonstrated that current parameters and its optimization is most important aspect for obtaining a good weldment. An Influence of process parameters and their influence on mechanical properties are explained in detail in light of microstructural details.

Welding Processes

The 5083 aluminium alloy is one of the alloys of the 5xxx series that is widely used in defence and shipbuilding industries. In this study, the 5083 aluminium alloy plates were evaluated through two friction stir welding and tungsten inert gas welding (TIG) by a double groove weld with a 30° angle and a 2mm gap for TIG and a simple butt weld for FSW. In this study and in addition to examining the samples' mechanical properties, the microstructure changes and the hardness were also reviewed. The results show that the FSW weld has better mechanical properties than the TIG weld due to fast welding speed. However, by preparing the pieces, the mechanical properties of TIG get closer to those of FSW. In the FSW welding in the weld nugget, the grains have a fine and co-axial structure, and an increase in the advance rate will reduce the inlet heat and make the grains smaller. Nevertheless, in TIG welding at high speeds, the grains become more extensive with increased inlet heat.
