Non-destructive testing (NDT) is a wide group analysis techniques used in science and industr evaluate the properties of a material, componet system without causing damage. NDT is divided into various methods of nondestructive testing, each based on a particular sci- tifi principle. These methods may be further subdivided into various techniques. The various methods and techniques, due to their particular natures, may lend themselves especially well to certain ap- plications and be of little or no value at all in other applications.
WELDING TRAINING PROGRAM PREPARING FOR A CAREER AS A WELDER
Learn to become a combination welder by training in 4 different welding processes:
WELDING PROGRAM OBJECTIVES
Students in Nexora internship Welding program will learn about the procedures and equipment required to weld using Gas Metal Arc (GMAW), Shielded Metal Arc (SMAW), Flux-Cored Arc (FCAW) and Gas Tungsten Arc (GTAW) welders. Students will also learn how to weld in the flat, horizontal, vertical and overhead positions used for plate or sheet metal, and the fixed, rolling and overhead positions used for pipe.
