Technology — Welding Technology — Welding COURSES OF INSTRUCTION 040. Sheet Metal Principles—This course describes the basic theory and processes in sheet-metal work; it discusses the use of hand, bench, cutting and layout tools. It also discusses the use of sheet-metal machines and accessories such as bar folders, hand shears, squaring shears, slip roll forming machines, crimping machines, turning machines and burring machines. (10 hrs./wk.) 041. Sheet Metal Processes—This course covers the theories and operations most common to hand processes, machine processes, measurement and layout. (15 hrs./wk.) 042. Sheet Metal Drafting—This course offers instruction in the principles of drafting with specific emphasis on how they apply to aircraft and commercial sheet metal measurements and layout which includes flat-pattern development, parallels and radial-line development and triangulation. (10 hrs./wk.) 043. Aircraft Sheet Metal Principles—This course discusses the principles of aircraft structure, rivets and riveting, tool, metals, forming processes, fasteners, corrosion identification, prevention and structural repair. (10 hrs./wk.) 044. Aircraft Sheet Metal Processes—This course applies the skills learned to do actual construction, such as assembly and repair of typical aircraft structures. (15 hrs./wk.) WELDING The Welding curriculum is designed for the student who wishes to major in welding. The various aspects of electric, oxyacetylene and inert processes are included. General service courses are offered for those in related areas who wish to become familiar with the principles of welding as applied to their respective fields: NOTE: Sophomore year will not be offered 1973-74. Certificates of proficiency will be issued on attainment of previously agreed upon skill levels. A pre-vocational curriculum in this area consisting of courses 030, 031, 032, and 033, is designed to train students for entry- level skills in welding and fabrication. Special emphasis is placed on certification in vertical-up and over-head arc welding. COURSES OF INSTRUCTION 030. Oxyacetylene Processes—Beginning course for welding majors. The use of oxyacetylene equipment to perform welds, cutting hardfacing, surface-bonding, testing and inspection of sheet and plate steel welding with respect to the American Welding Standards. (10 hrs./wk.) 031. Principles of Gas Welding—Principles of oxyacetylene processes including fusion of mild steels, cutting techniques, and surface bonding of non-ferrous alloys. Emphasis on safety factors of gas welding. This course should be taken concurrently with 030, Oxyacetylene Processes. (10 hrs./wk.) 032. Electric Welding Processes—This course includes safety, and electrode selection; inspection of arc welding and hard surfacing; structural joint designs such as butt, lap, and fillet welds on mild steel plate; and cast iron welding. (15 hrs./wk.) 033. Principles of Arc Welding—Fundamentals of electrode design; fusion of steels; hard-facing of ferrous and non-ferrous alloys; and an emphasis on safety. This course should be taken concurrently with 032, Electric Welding Process. (10 hrs./wk.) 101.
