Course Description:
This course is designed to give you the skills and knowledge needed to perform basic welding operations using the Shielded Metal Arc Welding (SMAW) processes. Oxy-Acetylene brazing and flame cutting will also be covered. General information on metals and other commonly used welding processes will be covered as lecture topics
Within each process we will cover; Safety, Welding Terminology, Welding Equipment, Heat Settings, Angles, Joint Construction, Rod Selection, Metal Selection, and Various Welding and fit up Techniques.
Grading in most cases will be a letter grade, based on the following:
1. Attendance 10% - This represents your effort. 2. Lab exercises and assignments 50% - This represents, a) ability to follow verbal and written instructions. b) comprehension of exercises. c) degree of improvement.
3. Two written exams 40%. There will be a mid-term exam covering the Oxy-Acetylene process and a final exam covering the Shielded Metal Arc Welding process.
INSTRUCTORS POLICIES:
1. You will be provided welding gloves and safety glasses for lab work.
2. You are responsible for cleaning up after yourself at the end of class.
3. Do not eat, drink, or smoke at the welding stations.
4. Do not waste metal or welding rod. Ask if you’re not sure what to do with it!
5. You will be working on your own projects during the last quarter.
