Abstract

The article discusses why welding engineer can be a good career choice for aspiring engineering students. The welding industry has an excellent safety record, robots now perform many of the repetitious and difficult tasks, and a mature and sophisticated scientific knowledge base supports welding practices. The region under the heat source melts forming a liquid metal puddle called the weld pool. A small solid region next to the weld pool, where the structure and properties of the workpiece are changed by heat, is called the heat-affected zone (HAZ). There are compelling reasons for detailed understanding of heat transfer and fluid flow in welding. Both the temperatures and velocities at all locations in the weld pool affect not just its shape and size, but the mixing of the filler metals, cooling rates at different locations, vaporization of alloying elements, weld metal composition, and the structure and properties of the joint.
