Qualified welding instructor required.

The Welding Honor is perhaps of all the AY honors, the one with the greatest potential to cause injury. If done wrong you can also create unsafe equipment (see requirement note at end) Do not attempt to teach yourself how to weld. An experienced instructor is absolutely required for this honor.

2a

Welding hood




2b

GMAW welding wire




2c

SMAW power supply




2d

Welding gas regulator




2e

GMAW welding torch




2f

220-volt electrical outlet




2g

PAC torch





3

Explain the following terms:



3a

Fusion welding




3b

Electrode




3c

Oxidation




3d

Slag




3e

Alloy





4

Select and describe one fusion welding process.



4a

How is heat generated?




4b

Why is filler metal added?




4c

Describe how the molten metal is protected from oxidation.





5

Name at least one thermal and one mechanical cutting process.



5a

Describe how each one works.




5b

Discuss relative advantages and limitations of each.





6

Demonstrate a knowledge of risks and hazards associated with welding and cutting, and the steps to prevent or reduce them.



6a

Electric current




6b

High temperatures




6c

Ultraviolet radiation




6d

Toxic fumes




6e

Moving machinery/blades




6f

High-pressure gases





7

Describe the safety gear required for various fusion welding and cutting processes.



7a

Head/eye protection
