Developed during a project designed to provide continuous, performance-based vocational training at the secondary and postsecondary levels, this instructional guide is intended to help teachers implement a laterally and vertically articulated secondary level welding program. Introductory materials include descriptions of Welding I and II, descriptions of secondary and postsecondary welding programs, postsecondary course descriptions, some guide organization notes, a discussion of sample tests provided in the guide, and suggested instructional time. In addition to an orientation, nine units are provided on these topics: welding safety, welding math, measuring, oxyacetylene cutting/welding, arc welding, operating gas metal arc welding equipment, gas tungsten arc welding, weld testing, and blueprint reading. Suggested instructional time and task listings begin each unit. For each task in a unit, some or all of the following are provided: performance objectives, performance actions, performance standards, recommended sources, related technical information, and other information the teacher might need. Suggested outcome-referenced tests are included. Appendixes include a sample proficiency report and exemption test, articulation materials, definitions, and test directions. (YLB)
