Description

Basic concepts and skills of cutting, tacking, and welding. Instruction on the breakdown and setup of oxy-fuel rigs; making different kinds of cuts and bevels on steel plate and pipe. Instruction on take-offs and fitting up butt welded fittings on a spool. Beginning welding concepts will also be discussed. Instruction on basic positions of welding on plate.

Course Objectives

The student will be able to:

  1. Set up and break down an oxy-fuel torch setup
  2. Explain the applications of an oxy-fuel torch; adjust the torch to the appropriate mixture of accelerant and fuel
  3. Understand the science and concepts behind oxy-fuel cutting
  4. Make different cuts on both plate and pipe, including square cuts and bevel cuts
  5. Fit up a variety of basic butt weld fitting, including building a complete spool
  6. Run stringer beads in the flat, horizontal, and vertical position on plate

Course Content

  1. Set up and break down an oxy-fuel torch setup
    1. Explain how to correctly set up and break down the oxy-fuel torch
    2. Go over all the safety procedures involved with the torch
  2. The applications of the oxy-fuel torch; adjust the torch to the appropriate mixture of accelerant and fuel
    1. Explain the different kinds of flames produced by the torch
    2. Go over different sizing and tips of the torch, and applications of each torch tip
  3. Understand the science and concepts behind oxy-fuel cutting
    1. Understand the chemical reaction that takes place in oxy-fuel cutting
    2. Go over the metallurgic change in that steel that takes place from heat
  4. Make different cuts on both plate and pipe, including square cuts and bevel cuts
    1. Show proper technique on holding the torch
    2. Show how to cut angles on both plate and pipe
  5. Fit up a variety of basic butt weld fitting, including building a complete spool
    1. Show how to use fit-up tools, including squares and levels
    2. Explain different bevels for different welding procedures and the process of fabrication of spools
  6. Run stringer beads in the flat, horizontal, and vertical position on the plate
    1. Explain beginning concepts of welding
    2. Show how to run stringer beads on a plate

Lab Content

Students will work individually and in teams on a spool project. They will go through the process of figuring out their take off dimensions, making their cut lengths, and fitting up their spool. They will also begin welding stringer beads on plate.

Special Facilities and/or Equipment

Cutting lab, weld bay, welding machines, and oxy-fuel torch.
