PREDICTION OF TIG AND MIG WELDING PARAMETER BY COMPARISON OF HARDNESS
Shashikant Rai, Dr. Lokesh Singh
ABSTRACT
The choice of the welding depends on several factors; primarily among them are the compositional range of the material to be welded, the thickness of the base materials and type of current. TIG and MIG welding has several advantages like joining of dissimilar metals, the absence of slag, low heat affected zone and etc. Since input parameters play a major role in determining the quality of a welded sample. A plan of experiments based on Taguchi technique has been used to design of experiment, acquire the data and to predict the welding parameters as well as the process parameter in terms of hardness. An Orthogonal array and analysis of variance (ANOVA) are employed to investigate the welding characteristics of alloy Steel material and predict the welding parameters also compare it in between the TIG and MIG welding Hardness responses.
