What is the difference between welding engineering and welding technology?

Welding technology is the study and application of the many processes of joining various metals. Welding Engineering is a far deeper study and application into the individual characteristics of each metal. A welding engineer will decide what metals are used in a project and what process to weld those metals. Weld techs will usually just receive blue prints and weld as instructed. Welding technology is usually a 2 year degree, and Welding Engineering is a 4+year degree.
