Welding Safety and Cutting Processes
The first course of the welder program, followed through an apprentice's first jobs at a fabrication shop in Pasadena, on the Houston Ship Channel: the trade and the apprenticeship, welding hazards and PPE with filter shade selection, fume, ventilation and respiratory protection, confined spaces, electrical safety and the welding circuit, fire prevention, hot work permits and fire watch, compressed gas cylinders and regulators, oxyfuel equipment, setup and cutting technique, plasma arc cutting, air carbon arc gouging and other thermal cutting, saws, shears, grinders and edge preparation, and a capstone refinery cutting job planned with a job hazard analysis, with OSHA's welding rules, ANSI Z49.1 and NFPA 51B throughout.

What you'll learn
- Describe the welder's trade, registered apprenticeship and qualification testing, the codes that govern structural and pressure welding, and how a fabrication shop is organized for safety
- Identify the radiation, heat, fume, electrical, fire, gas, noise and physical hazards of welding and cutting, and apply the hierarchy of controls to them
- Select and inspect eye and face protection with the correct filter shade, flame-resistant clothing, gloves, footwear and hearing protection
- Explain the health effects of welding fume and gases, calculate time-weighted averages and hood airflow, and choose ventilation and respiratory protection
- Recognize confined space hazards for hot work, including oxygen deficiency and enrichment, and follow entry permit, testing and attendant requirements
- Explain the welding circuit, open-circuit voltage and shock, connect the work lead correctly, and work safely in wet, enclosed and elevated locations
- Prepare a hot work area, complete a hot work permit, keep a fire watch for the required time, and handle containers that may have held flammable material
- Handle, store and connect compressed gas cylinders and regulators, and calculate gas contents by pressure and by weight
- Assemble, leak test, purge, light, adjust and shut down an oxyfuel outfit, and apply the acetylene withdrawal limit
- Make straight, pierced and beveled oxyfuel cuts, select tips and speeds from a chart, and diagnose cut faults from the cut face
- Set up and use plasma arc cutting and air carbon arc gouging, choose current, speed and consumables, and control their light, fume, noise and electrical hazards
- Use saws, shears and grinders safely, prepare bevels, root faces and clean joint edges, and plan and carry out a complete cutting job with a job hazard analysis and hold points
