Abstract

Tungsten Inert Gas (TIG) welding is used to join Aluminium Alloy 5052 because of its economic and good quality welds among the arc welding processes. Coarse grain’s structure formation and intermetallic formation in the weld zone that can reduce the strength of the weld can occur during the TIG welding process. Other than that, another problem that occurs is the behavior of Aluminium Alloy when being welded and tend to have defect, porosity and solidification cracking. Therefore, these problems can be solved by using the optimized pulsed current parameter such as the Peak Current (A), Base Current (A) Welding Speed (cm/min) of the pulsed current TIG welding. The welding process was performed by using OTC Robot Welding with filler 5356, butt joint with 3 mm thickness of the plate. The design parameter is generated by using Minitab Software and the tensile testing value will be the responses in this research. Moreover, the data will be analyzed by using Taguchi Methodology and Analysis of Variance (ANOVA). Grey Relational Analysis (GRA) is an effective tool for process optimization under limited number experimental runs. In Addition, the relationship between machining parameters and machining performance can be found out by using GRA. Therefore, the best parameter was obtained among the suggested parameter of TIG welding by using GRA.
