Microwave joining of metals: A Review

Microwave joining has received attention of researchers for joining of metals and alloys due to its major advantages like volumetric heating, selective heating of target materials, reduced heat affected zone, better physical properties, energy saving and eco-friendly. This paper present the state of the art major research developments in the field of microwave joining by broadly classifying the progresses in this field into four categories such as specimens to be joined; types of susceptors; interface powder based developments and progresses in experimental set-ups. An attempt has been made to bring out the major progresses related to microwave joining of metals.
