Pass a safety test on oxyacetylene welding 2. Identify the basic components of the oxyacetylene welding apparatus. 3. Set up, use, shut off, and store an oxyacetylene welder properly. 4. Use oxyacetylene equipment to braze mild steel. 5. Run a bead with the oxyacetylene equipment with and without filler rod. 6. Use the oxyacetylene equipment to do four basic welds other than a bead. 7. Select welding rods and fluxes appropriate for a the job. 8. Make a straight cut, using the cutting head. 9. Make a bevel cut, using the cutting head. 10. Pierce a hole in steel plate. 11. Clean the orifices in welding and cutting heads, using the approved technique. 12. Construct a simple project requiring cutting and welding. 13. Cut sheet metal (14 ga. or thinner) with the cutting head. 14. Change lenses on cutting goggles. 15. Observe phase change of metals when they are subjected to heat. 16. Describe how materials behave under applied stress. _______________________________________________________________________ REFERENCES: Cooper, Elmer L. (1987).
