Student Learning Outcomes

Upon successful completion of this course, students should be able to:

  1. Set up and adjust the power source for TIG welding on Mild steel, Stainless steel, Cast Iron, Aluminum, Magnesium, Titanium, and Copper.
  2. Demonstrate safety  procedures used in TIG Welding (Gas Tungsten Arc Welding).
  3. Explain the classification system used for tungsten electrodes.
  4. Prepare a Tungsten electrode for the material you are welding on.
  5. Clean the material and set up the material in preparation for welding.
  6. Identify different metals and procedures for welding ferrous and nonferrous metals.
  7. Define metallurgical terminology used in welding.
  8. Explain different weld defects and their causes.
  9. Demonstrate methods of fit up and the reduction of distortion.

Given lectures and lab demonstrations on the topics, the student will be assessed on each of these outcomes through traditional exams, quizzes, and laboratory assignments. Given  demonstrations by the instructor and many lab practice welds, the student will be assessed to industry standards by the American Welding Society D1.1 Welding Code Visual Acceptance with 80% accuracy.

The standards for the course outcomes will be measured against the text used for the course. A successful student will achieve a score of 70% or better on these assessments.



Student Electronic Access to Grades

D2L is the College’s Course Management System which includes a gradebook function allowing students access to their grades in order to receive timely and meaningful feedback on their progress in the course at any time. These grades will align with the Evaluation Criteria listed in this syllabus. D2L is accessed through the MyLCC page.

Whenever practicable, results for graded items should be posted electronically within 48 hours after the instructor has completed the grading process for the items, and final grades for the course should be entered no later than the specified grading day.
