A sample from this course

One topic, as StudyPath teaches it.

Resistance welding processes

Resistance welding processes use the heat generated by passing electric current through the joint to fuse metal parts. Mastering the types of resistance welding, the principles of heat generation, and the key parameters (current, time, pressure) is essential for the NUC CCMAS/NBTE/NCCE exams because they form the basis for design, inspection, and quality control of welded structures.
