Catalog Course Description
Studies cast iron and alloy steels that are used in the tool and die industry, the effects of the alloys on tools and dies, and how the welding process can be used successfully. Skill development in welding and repair of these cast irons and steels will incorporate both SMAW and GTAW processes. This course is an 70% hands-on laboratory experience. All students will be required to wear clothing appropriate to a welding environment. It is also recommended that the student bring a pair of slip-joint pliers.
