Description: This course prepares students for welder qualifications in several codes to meet the required standards of the pipe industry. The focus of this course is the welding procedures used on smaller diameter and heavier wall thickness piping. Students will practice butt welds, socket welds, tube welding and advanced pipe fabrication. Specialty industry procedures such as hot tapping, heat treatment and stress relieving will be discussed. Special safety procedures such as fall protection, cranes and rigging, confined space and excavations will be discussed. Prerequisites: WLD 245

Prerequisites: WLD 245

Corequisites: None

Recommendations: Students should have completed WLD 245 or have the comparable skill sets to be successful in this course.
