“…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]:…”

“…Sharma et al [10] described the joining of material through domestic microwave oven. Srinath et al [11] Researches bonding of copper in mass form within short duration through microwave energy and it was noted that consistent microstructure secured the uniform volumetric heating all around the weld region. An organized layer of SS-316 and MS was formed by the authors when implemented microwave joining of different metals with Ni based powder [12].…”

Abstract. Small and large scale (gas power plant, hydro power plant), automobile industries are suffering by failure of component. Sometimes, it is also observed that the component which was failed due to these reasons are very much costly and replacement of those also very difficult due to the complex geometry. By using Microwave hybrid heating, WC-12Co based clads were developed on austenitic stainless steel (SS304). Microwave clads were developed by introducing the preplaced, preheated powder for a duration of 15 min to microwave radiation at 2.45GHz frequency and 900 W power in domestic microwave applicator. By using optical microscope and scanning electron microscope (SEM), the developed clads were characterized. By using pin-on-disk, wear performance of the WC-12Co based clads and unclad samples were tested. It is observed that developed clad samples performed superior wear resistance than unclad samples.

“…The successful joining of bulk metallic materials using MHH was first reported by Sharma et al in the form of a patent [17]. Srinath et al [18,19] reported joining of similar as well as dissimilar materials using MHH. This paper discusses the joining of superalloy Inconel 718 plates using the hybrid microwave heating (MHH) technique in a multimode microwave applicator, and characterization of the joints in respect of microstructure, microhardness, and tensile strength.…”

Inconel 718 plates were butt welded through hybrid microwave heating (MHH) technique using Inconel 718 powder as a sandwich layer. Joining was affected through the fusion of the sandwich layer pre-placed between the bulk pieces owing to the heat generated while irradiated with 2.45 GHz microwaves for 480 s. Various phases present in the joint zone were detected using X-ray diffraction (XRD) while the microstructural features were characterized using an optical microscopy and scanning electron microscopy (SEM). The XRD patterns show the presence of Laves, δ(Ni3Nb) and carbide phases in the joint zone along with the main matrix. The microstructural study also reveals that there is not any interfacial cracking and microfissure in the joint zone due to uniform heating associated with the MHH process. The average microhardness of the joint was observed to be 245 ± 20 HV. The average ultimate tensile strength of the joint was observed to be 780 MPa with 11.11 % elongation.
