COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1. Demonstrate use of tools and equipment in a welding shop per American National Standards Institute (ANSI) safety standards Z49.

2. Perform arc weld from the flat, fillet weld position per AWS standards.

3. Perform oxy-acetylene weld on a butt joint, lap joint, fillet joint, and brazing fillet joint per AWS standards.

4. Demonstrate ability to safely use oxy-acetylene cutting torch per AWS standards.

 

Objectives:

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

1. Describe and demonstrate principles of welding safety per ANSI and AWS standards.

2. Identify components of oxy-acetylene welding and cutting equipment.

3. Recognize a transformer, rectifier, and motor generator type welding machine.

4. Explain electrical terms, including AC and DC welding current.

5. Identify components of shielded metal arc welding equipment.

6. Safely set up and place in operation oxy-acetylene and shielded metal arc welding equipment.

7. Differentiate between plain carbon steel, alloy steel, ferrous metals, 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, in the flat position, a multipass fillet weld in the horizontal position, a lap joint and a fillet weld in the vertical down position using shielded metal arc welding.

11. Identify filler metals for oxy-acetylene and arc welding.

12. Recognize uses and purposes of a light, medium and heavy flux coated arc welding electrode, such as E-6010, E-6011, E-6013, E-7014, E-7018, and E-7024.
