Heat treatment jobs focus on using heating equipment to repair and offset any damage done to the materials by a welding process. In this role, you may use controlled processes like induction techniques to provide post-weld heat treatment (PWHT) and strengthen the material after exposure to a high temperature. Most heat treatment positions focus on previously welded materials, but employers may also ask you to use heat treatment for other purposes, such as strengthening the surface hardness of materials. This is a time-sensitive job because the speed of change between heating and cooling is an integral part of the heat treatment process. The ability to manage your time effectively is essential to your success.
