4. Review Questions - #1- #10
6. What is the number on rule in the shop? 7. What is the term for anything that poses a danger? 8. What are the three causes for accidents in the shop? 9. What pressure (PSI) should Oxygen be set to? 10. What pressure (PSI) should acetylene be set to?

5. Welding PPE Wear safety glasses and welding gloves
Always use pliers to handle hot metal
Don’t pick it up with your gloves
Wear long jeans or overalls
Wear close toed shoes, pull hair back and no loose clothes or jewelry

6. Arc Welding Using Electricity to fuse two pieces of metal together
Needs three things to weld
Heat source
Shielding
Filler material

7. Shielded Metal Arc Welding (SMAW)
Also known as Stick Welding
Uses electricity to supply heat
The consumable stick electrode provides the filler material
The gas shield is provided by the flux around the electrode

8. Stick Welding Safety Make sure that your work area is clean and dry
Check your ground clamp to make sure that you have a good connection
Let hot pieces of metal cool off between welds

9. Stick Welding Safety NEVER NEVER NEVER Look at the Arc!!
Always wear a helmet when welding
Before striking an Arc yell “Cover”
When you are done, clean your slag off with a wire brush or chipping hammer

10. Stick Welding Safety
NEVER lay the electrode holder down when the machine is turned off
If your electrode sticks to the metal, turn off the machine first
Clean slag off weld when completed
Keep ground as far from
arc as possible

14. Chipping Hammer

15. Wire Brush

16. Make Sure that your Work clamp is attached to the metal or it will not work

17. Starting a Welder Turn the knob to adjust to the right amperage
Make sure you are ready to weld before you turn on the machine

18. 2 Methods to Starting a weld
Tapping – Keep tapping the electrode on the metal until the arc is started
Striking – Strike the electrode against the metal like striking a match

19. Keeping the Arc Welding is done by melting metal together.
Once you’ve struck your arc, keeping moving the metal pool along until you are at the end of the metal

20. After Welding
Once you are done welding, place the metal in water to cool it down
Only pick it up with Pliers!!!!!
Using your chipping hammer or wire brush, brush away all of the slag
Slag is the black stuff that will be on top of your weld
Slag makes your weld look bad and could make the metal weaker if you weld on it

21. After Welding Slag – black material covering the welding
This can be cleaned off by:
Chipping Hammer
Wire Brush

22. Make Adjustments If you cant get the arc to start, turn up the metal
If your metal is burning holes through it, its too hot and you need to turn it down!!
Look to see if your going too fast or too slow

25. Good or Bad?

26. A Good Weld is… Even all the way across Straight Deep Penetration
Strong – Wont Break
