Optimization of Microwave Welding Process Parameters for Hardness Using Taguchi’s Method

Joining of metals using microwave radiations is really an innovative idea in the field of research. In this paper, Graphite plate is used as a separator, Nickel based powder is used as the interfacing material, Mild Steel (MS) and Stainless Steel (SS) are used as substrates. This paper elaborates the use of Taguchi experimental design technique for maximizing hardness of microwave welded joints. Using ANOVA and signal to noise ratio of robust design, effect on hardness of Microwave joining process parameters (Exposure Time, Interfacing Material and Substrates) is evaluated and optimum welding condition for maximizing hardness is determined.
