ABSTRACT

Optimization of Weld Bead Geometry in Tig Welding of Copper Matrix Composite using Response Surface Methodology

Arulraj.M., Palani P.K. , Venkatesh.L.

ABSTRACT

Copper-based composite emerges as a promising material for engineering applications due to their excellent thermo physical properties coupled with better high temperature mechanical properties compared to pure copper and copper alloys. This paper deals with welding of copper matrix composite using gas tungsten arc welding. The process parameters considered in this study are arc voltage (V), welding current (I), and welding speed (S). The weld bead characteristics such as weld bead height (BH), bead width (BW), and bead penetration (BP) are the response parameters. The experiments were conducted based on Box-Behnken design with 3 factors at 3 levels. Using the results mathematical model was developed. The adequacy of the model was evaluated using analysis of variance (ANOVA). The optimum welding parameter settings were also determined using Response Surface Methodology. Keywords: TIG welding, Copper Matrix Composite Materials, Weld Bead Geometry, Response Surface Methodology.
