A review on heating mechanism, materials and heating parameters of microwave hybrid heated joining technique

Recent microwave hybrid heating (MHH) is environmentally benign and cost-effective, and may increase manufacturing product quality. MHH has attracted interest from materials joining researchers due to its many benefits, resulting in a novel technique. The primary aim of this review paper is to offer a comprehensive examination of the heating mechanism, material characteristics, and parameters related to microwave-based materials processing. The purpose of this comprehensive examination is to deepen our comprehension of the particular requirements associated with this field. The benefits and heating mechanism of MHH were elucidated by a comparative analysis with the conventional heating approach that does not use susceptors. The materials analyzed in this research comprise susceptor material, insulator material, and interface material. The impact of microwave power and exposure time on the quality of the joint was succinctly stated. Relevant investigations indicate that metal joint can be achieved by subjecting it to a temperature of 300 s at 900 W and 2.45 GHz using MHH technique. This demonstrates the high efficiency of MHH. The objective of this study is to provide researchers in the field of microwave hybrid joining (MHJ) with clear and concise guidelines and support. This study investigates the current state of research on MHH technology in the field of material joining, with the goal of promoting the advancement of MHJ development.
