Study the Effect of Welding Parameters on Distortion of AA6061- T6 Butt Joints Made by MIG Welding (Robotic GMAW

Abstract

The main goal of this study is to look into how Gas Metal Arc Welding affects the shape of AA6061-T6 aluminum when it is welded (GMAW). Variations in Voltage (V), Wire Feed Speed (WFS), Gun Angle (GA), Travel Speed (TS), Distance from the nozzle to the Spot to be Welded (DISW), Root Gap (RG), and Root Face (RF) are used as welding parameters. This gives the Simufact software the information it needs to simulate the arc welding process at a room temperature of 20°C. The simulation results from Finite Element Analysis (FEA) software show that the amount of distortion is large, so simulating the welding process helps people understand how welding works and compares to experimental results. The results also show that there is a link between the parameters of welding and the amount of distortion. The type of welding wire is 5356. It has a 1.2 mm diameter and is made of 100% Argon. It has a 25 cfh flow rate. CMM was used to measure samples of welding to find out how much and what kind of distortion there was. The experiments are planned with the help of the Taguchi method, and Artificial Neural Network (ANN) modeling is used to predict how the joints will bend. The results show that the main things that cause or change distortions are wire feed speed, voltage, and travel speed. When the wire feed speed and voltage are both increased at the same time, distortion gets worse. This shows that these parameters and variables in welding have a big effect on distortion.
