This course, adapted from military curriculum materials for use in vocational and technical education, provides training in the theory and practice of sheet metal work. Designed for student self-instruction (such as a correspondence course), the text consists of four volumes. Volume 1 discusses shop mathematics, measurement and layout tools, working drawings, sheet metal layout, and sheet metals. Volume 2 covers fastening hardware and devices for sheet metal; sheet metal drilling and punching equipment; folding, forming, and seaming equipment; and soldering, spot welding, and sealants. In volume 3, instructions are given for assembling sheet metal components and making joint connections to fasten the components together. It also covers fabricating, installing, and repairing sheet metal components of heating and ventilating systems, fixed utility equipment, roofing, gutters, and downspouts. The final volume discusses supervisory responsibilities and personnel management, supervision of sheet metal fabrication and repair operations, determining job requirements, and inspections and evaluations. Each volume is accompanied by a student workbook containing a study reference guide, chapter objectives, chapter review exercises keyed to the text with answers, and volume review exercises keyed to the text.
