Effect of Process Parameters in MIG Welding on Mild Steel IS 2062

摘要

The main objective of this paper is to predict and optimize MIG welding of some economically important similar materials or dissimilar materials in industry through applying a statistical approach to SPSS software, develop mathematical models and optimize the welding operation. This was achieved by controlling selected welding parameters; V-butt angles, welding current and welding voltage position, to relate the ultimate tensile strength to the selected input welding parameters. The materials studied in this work are Mild steel IS2062. The experimental results which are obtain corresponding to the effect of different V-angles such as 30°, 45° and 60° at, different welding current such as 80 Amp, 100 Amp and 110 Amp and various welding voltage 17 Volt, 19 Volt and 20 Volt on ultimate tensile strength of welding of Mild Steel IS2062, are used to find out the significance of input parameter on output by using SPSS and ANSYS method, static analysis and thermal analysis. This result shows better ultimate tensile strength prediction capability and applicability to such industrial MIG welding leading to effective selection of machining parameter for better ultimate tensile strength.
