NOTES:

STUDENT LEARNING OUTCOMES:
  • Students will become aware of the safety practices related to arc welding equipment and processes. Student MUST pass the safety test in order to continue the course.
  • To learn the basic differences of commonly used electrodes such as their physical and mechanical properties.
  • To learn how to select the correct electrode for the job at hand.
  • AC and DC machines, how they are best used.
  • Students will learn the properties related to energy such as melting point, weldability, fusibility, volatibility, electrical and thermal conductivity, electrical resistance, coefficient of thermal expansion, hot shortness, and overheating.
  • Students will study the most commonly used types of steel and effects of the most commonly used elements in making steel.
  • Students will learn the symbols in order to read welding blueprints.
  • To explain the American Iron and Steel Institute (AISI) and the Society of Automotive Engineers (SAE) numbering system for the various grades of steel.
  • Manipulative skills and techniques will be developed in this course as a result of time to practice.
