MTGN584. NON-FUSION JOINING PROCESSES A study of the joining processes in which the base materials are not melted. Brazing, soldering, diffusion bonding, explosive bonding, and adhesive bonding are the processes to be examined. The theoretical aspects of these processes, as well as the process parameters will be discussed. Special emphasis will be given to the joining of dissimilar materials using these processes.
