COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

The student will:

1.   Describe and demonstrate principles of welding safety.

2.   Identify components of oxy-acetylene welding and cutting

    equipment.

3.   Recognize a transformer, rectifier and motor generator

    type welding machine.

4.   Explain the principles of the AC and DC welding current.

5.   Identify components of gas metal arc welding equipment.

6.   Set up and place in operation oxy-acetylene, arc and gas

    metal arc welding equipment.

7.   Differentiate between plain carbon steel, alloy steel,

    ferrous and non-ferrous metals.

8.   Produce a sample butt joint, lap joint, fillet weld and

    braze welded fillet using the oxy-acetylene welding process.

9.   Produce a sample of free hand flame cutting and straight line

    beveling and piercing.

10.  Produce a sample of stringer beads, padding, weaving in the

    flat position, a multipass filet weld in the horizontal

    position, a lap joint and a fillet weld in the vertical down

    position using shielded metal arc welding.

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 problem solving assessments and 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 - 35%
Homework problems, Quizzes, Exams
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 30 - 50%
Class performances, Performance exams
Exams: All forms of formal testing, other than skill performance exams.		Exams 15 - 35%
Multiple choice, True/false
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 5 - 10%
