2.   Identify the five basic types of welding joints.

3.   Prepare a sample of cast iron for welding.

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

    tungsten and gas metal arc welding equipment.

5.   Demonstrate air arc principles.

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.

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%
