State of Art:Joining of Microwave Processed Materials

Microwave processing is relatively advanced and unfamiliar technique of joining metals and ceramics. Microwave energy has been effectively used in the processing of different materials. It has been introduced in the field of manufacturing and design due to its various advantages over other welding/joining techniques such as - short heating time, hybrid heating, saving energy etc. Microwave heating leads to generation of inverted temperature profile and provides selective heating and as well as volumetric heating. Joining of bulk pieces of similar/dissimilar metals which have high thermal conductivity is really challenging. Microwave processing has numerous advantages over traditional methods of heating. It has been commonly used in various industrial, scientific and medical applications for processing, drying and heating. In the past years, various works has been done on polymers, ceramics except metals by using microwave radiations. Many initiatives have been taken to explore this advanced and emerging technique in various fields of engineering.
