This course introduces students to the macroscopic and microscopic aspects of different types of welding. Students will experience and learn different welding techniques such as MIG, TIG, Stick, and Oxyacetylene welding. Actual practice with the latest technologies such as MIG and TIG will reinforce concepts and provide practical hands-on experience. Several sample test parts will be welded in a lab and broken with a tensile tester to evaluate the calculated load compared to the welded joint strength. Weld samples will also be microscopically inspected to determine the HAZ (heat affected zone) of the material. Oxyacetylene and plasma cutting will be experienced. Interpreting weld symbols on drawings will be learned and applied. **Possible lab fee associated with this course.**
