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.
−
==2. Explain the safe working pressures of oxygen and acetylene, as per your instruc­tor's directions, for various procedures. ==
+
<noinclude></translate></noinclude>
−
==3. While blindfolded, demonstrate ability to hook up an entire oxyacetylene kit, including tanks, gauges, hoses, and torches, and light the same.** ==
 
−
==4. As per your instructor's directions, weld two mild steel test plates (1/8 inch x 1 inch x 8 inches) (0.3 cm x 2.5 cm x 20.3 cm) in horizontal, and vertical positions.==
 
−
==5. Use a cutting torch and demonstrate your skill by making one 12 inches (30.5 cm) straight-line cut, one circle cut of at least 3 inches (7.6 cm) in diameter and one 3 inch (7.6 cm) star cut. The cuts are to be made on mild steel plate at least 1/4 inch (0.6 cm) thick. ==
 
−
==6. Demonstrate your ability to braze a cast-iron object with at least 1/4 inch (0.6 cm) double bevel butt weld 2 inches (5 cm) long.==
 
  
−
==7. Explain the safety precautions and safety equipment normally used in electric welding in relation to eyes, hands, and exposed skin areas. Why should the tank valves never be oiled? ==
+
{{ansreq|page={{#titleparts:{{PAGENAME}}|2|1}}|num=1}}
−
==8. Explain the difference between oxyacetylene and electric arc welding. ==
+
<noinclude><translate><!--T:160-->
−
==9. Demonstrate ability to select from an electrode guide the proper amperage and electrode for various types and thicknesses of metal. ==
+
</noinclude>
−
==10. Demonstrate ability to weld flat, vertical, horizontal, and overhead on (1/8 inch x 1 inch x 8 inches) (0.3 cm x 2.5 cm x 20.3 cm) mild steel test plates. ==
+
<!-- 1. Successfully complete a minimum of three hours of classroom instruction.* -->
  
−
==Note: An instructor is a must. Welding is a very critical and serious skill to learn and is not a home-type course. Welding essentially takes the place of bolts and rivets, and if not properly done, is most dangerous. Example: A trailer hitch not properly bond­ed, or machinery exposed to the strain of pull or weight, is an invitation to disaster.==

==Note: ** This requirement demonstrates one's skill in working in darkness, such as in an emergency. All acetylene connection threads are left-handed, while all oxygen connection threads are right-handed. ==

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
