MIG welding, also known as Metal Inert Gas welding is being widely used in industries due to its economic advantage. Quality of the welded joint is the main concern, which is a difficult task if input process parameters taken are not proper or well optimized. So, the detailed review of various design of experiments and optimization techniques have been discussed in this paper for obtaining optimal input process parameters. The output parameters such as tensile strength, microhardness, weld pool geometry etc. depend upon the input parameters i.e. wire feed rate, welding current, voltage of arc, gas flow rate, welding speed etc. These parameters are optimized by using various experiment design techniques like Response Surface Methodology, Taguchi, Factorial design. Optimization is done by using Grey Relational Analysis, Artificial Neural Network, Particle Swarm Optimization. Analysis of Variance is used for checking the model adequacy. Mathematical models are generated using regression analysis.Keywords
Optimization, MIG Welding, Weld Pool Geometry, Microhardness.

This paper is going to deal with the effect of Boron Carbide (B4C) and Rice Husk Ash (RHA) in AA7075 Hybrid Composite. To study the effect of the addition of reinforcement on AA 7075, the fabrication is done by using bottom pouring type stir casting machine.K2TiF6isadded as filler to avoid the wettability problem of liquid molten aluminium alloy 7075 and B4C.The results shows that the hardness of the hybrid composite is increased with increase in the wt. % of reinforcements. Scanning Electron Microscopy is used to confirm the microstructure of composite and distribution of reinforcements. The results of Energy Dispersive Spectroscopy analysis is used to confirm the elements in Al 7075/B4C/RHA hybrid composite and some useful conclusions are made.Keywords
