6. Identify filler metals by American Welding Society (A.W.S.D.) specifications.
7. Demonstrate welding in flat, horizontal and vertical postions.
8. Prepare plates for certification test in accordance with A.W.S.D. 1.1 structure code.
9. Describe the metal surfacing processing.
10. Discuss the reasons for preheating in welding.
11. Assemble gas tungsten/gas metal arc welding equipment for welding.
12. Identify common sheilding gasses for welding mild steel,
stainless steel and aluminum with the gas metal arc welding process.

Methods of Evaluation/Basis of Grade.
Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing. | Writing 0 - 0% |
None | |
This is a degree applicable course but assessment tools based on writing are not included because skill demonstrations are more appropriate for this course. |
|
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills. | Problem Solving 10 - 20% |
Homework problems (handouts). | |
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams. | Skill Demonstrations 50 - 60% |
Welding skills assignments and performance exams. | |
Exams: All forms of formal testing, other than skill performance exams. | Exams 10 - 20% |
Quizzes and final exam: Multiple choice, True/false, Matching items, Completion | |
Other: Includes any assessment tools that do not logically fit into the above categories. | Other Category 0 - 10% |
