This paper deals with Microwave welding using stainless steel grades.The field of microwave joining had taken a great leap in the past decade, Due to its special and exceptional characteristics like selective heating, volumetric heating and inverted heating profile its has been introduce in the field of the microwave joining of materials ,previously which was limited only to the processing of food. It also has an edge over conventional methods due to these characteristics. Microwave energy is generally new area of topic in material welding or material joining even though it has been introduced already in many industries like medical, food processing, drying. This process with the help of microwave radiations deals with joining of similar and dissimilar materials. These joints were characterized using various techniques.
