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 princples 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.

11.  Produce a sample lap joint, fillet weld using the gass metal

    arc process.

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

13.  Recognize a light medium and heavy flux coated arc welding

    electrode.
