Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Function safely in a welding shop environment.
  • Demonstrate professional work ethics.
  • Apply math and science concepts to the welding related process.
  • Operate oxyfuel portable and track cutting systems in accordance with industry standards.
  • Interpret drawing and symbols to accurately layout a project; prepare an assemble to specified tolerances; and weld joints in accordance to AWS D1.1., Structural Steel Code.
  • Weld common joint configurations with the SAW process to code quality standards in the flat and horizontal positions.

Outcome Assessment Strategies

The student will be assessed on his/her ability to demonstrate the development of course outcomes. The methods of assessment may include one or more of the following: oral or written examinations, quizzes, observation, written assignments, visual inspection techniques, welding tests, safe work habits, task performance and work relations.
