Instruction:
This introductory course to welding technology covers the theory and techniques of operating MIG (Metal Inert Gas), TIG (Tungsten Inert Gas) and Metal Arc welding machines, oxy-acetylene burning and welding, and heat treating with an emphasis on basic welding and procedures. Topics include setup and use of equipment, tool, equipment and industrial safety and health practices, hand tool and power machine use, measurement, laboratory operating procedures, welding power sources, welding career potentials, and introduction to welding codes and standards. Training involves welding in a variety of positions and directions. By performing welds in different positions on various types of material, students achieve proficiency in performing each major welding process.
Credit recommendation:
In the lower division baccalaureate/associate degree category, 3 semester hours in 3 semester hours in Welding, Art, or General Technology (7/12).
