ABSTRACT

This chapter focuses on the following typical induction joining applications: brazing, soldering, bonding, and shrink fitting. Brazing and soldering are two of the most popular induction joining applications, which are accomplished in a similar manner to other induction thermal processes such as hardening, except quenching usually does not apply and the required temperatures might be somewhat lower. Brazing and soldering using electromagnetic induction have several other advantages compared to heating the workpieces with a flame or brazing furnace. Frequency selection for brazing applies the same guidelines as for other induction heating applications of similar geometry. Induction bonding and induction sealing provide the needed closure of such components as hoods, fenders, and other parts used in the automotive industry, as well as bonding various electrically conductive materials to proprietary electrically nonconductive materials. Shrink fitting is a method of joining components without the use of a filler material.
