Investigation of Stainless Steel Joint Fabricated Through Microwave Energy

A Review on Green Technology Material Processing Through Microwave Energy

“…A. Sonnad et al [6] Gupta and Kumar [9] have discussed the joining of stainless steel 316 by microwave energy using Nickel based powder as a sandwich layer and domestic microwave oven. The developed joints were crack free however small porosity is observed during micro structural investigation n and observed that with increase in Nickel content and exposure time, the joint tensile strength increase significantly.…”

Feasibility Study on Joining of Copper Pipes Using Microwave Energy

“…The microwave joining of bulk metallic material was established in year 2009 [14] and was reported in the form of Indian patent. It was reported by few researchers that microwave energy can be used for joining of bulk metals such as copper, mild steel, stainless steel plates [15][16][17][18][19][20][21][22][23]. It has been reported by researchers that use of microwaves for joining of bulk metals have revealed that the process is capable of producing joints in lesser processing time with better mechanical and metallurgical properties than conventional processes.…”

“…Heat generation with heat transfer from (inside) core of the material to (outside) surface of material takes place in microwave processing which is reverse in case of conventional heating. It has been reported that microwave energy is used to joined engineering materials such as metal, ceramics, polymer, CMC's and PMC's due to the unique heating characteristics such as volumetric and selective heating, Eco-friendly, power saving and reduction in processing time [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]:…”

Comparative Analysis of Microwave based Joining/Welding of SS304-SS304 using Different Interfacing Materials

“…Mild steel and stainless steel were joined by used of nickel based EWAC powder. Gupta and Kumar [2] worked on welding of SS420 with SS420 used nickel based EWAC powder as an interface material. Slurry is made by 95% nickel based powder and 5% blumer 1450XX.…”

“…This technique in not fully developed as compared to other joining techniques but results of this technique are relatively better in terms of hardness, HAZ and tensile strength. Many materials which are extensively used in industries like aluminium, stainless steel, cast iron, etc [1][2][3][4][5][6][7][8]. has been joined by microwave joining process.…”
