This chapter presents various hybrid joining methods with their importance presented from the available literature. It discusses hybrid fusion welding, hybrid solid-state welding, hybrid resistance welding, hybrid adhesive bonding-spot joining, hybrid brazing and soldering, and hybrid weld surfacing. Mechanical fastening, adhesive bonding, brazing, and soldering are the widely used joining processes. Each joining process has its own advantages. The chapter focuses on welding processes such as laser–metal inert gas (MIG) hybrid welding, laser–tungsten inert gas (TIG) hybrid welding, TIG–MIG hybrid welding, and hybrid plasma–arc welding. The laser–MIG hybrid welding technique has been developed to combine the advantages of both the processes in order to meet the welding industry needs. Different types of laser sources have been used with MIG welding process. In the laser–MIG hybrid welding processes, laser beam is traversed prior to the MIG torch. In the case of laser–TIG hybrid welding processes, arc generated by conventional TIG welding process is combined with the laser beam to join materials.
