Welding is the ubiquitous process of permanently joining materials together. Essentially every industry requires welding, either for fabrication or repair. It is hard to imagine modern society without the ability to assemble complex structures quickly and effectively from smaller sections of material or sub-assemblies or make repairs. A proper weld is the culmination of skilled labor, heat, pressure, and metallurgical conditions. The combination of these factors requires special welding procedures to ensure components perform satisfactorily in service.

Many excellent articles have been written on the various welding processes, types of welds, joint types, weld design, etc., but understanding the process and designing welding procedures that ensure a successful weld from a metallurgical perspective can be overlooked. From titanium to tool steel, this work provides specific insight into electrode selection, chemical compatibility, preheat temperatures, post-weld heat treatments, and even methods to repair difficult-to-weld materials.

This course provides you with more advanced aspects of welding procedure with a focus on specific metals and their microstructure. Additionally, valuable information on hard surfacing and welding repair is provided. Essentially, the engineer will have a better knowledge of metals and how to weld them.

This course is aimed specifically at civil, mechanical, structural, and process engineers, but facility managers, H & S professionals, environmentalists, energy auditors, and anyone who wants a more advanced understanding of welding principles will benefit.
