I have prepared some riddles to improve your
concentration and interpretation skills. This
riddles are connected to our new topic which
will be revealed later on. Anyone who can
guess first the correct answer will be
rewarded.
DIRECTION:

7. Keep me fed, full, and fat,
With notes, cards, and coins at that.
Take me with you wherever you go,
Just make sure I never run low!
W__L__

8. WALLET

9. Green, brown, and tall,
I shed a lot in the fall.
I give you flowers, I give you fruit,
Dig deep to find my roots!
__E_S

10. TREES

11. Shiny, juicy, crunchy, and red,
Bite me raw or in a pie instead.
You should eat me every day,
I’m all you need to keep the doctor away!
_P__E

12. APPLE

13. I am the element found in just about
everything. I am the air you breathe, and support
the growth of all living things. What am I?
__Y_E_

14. OXYGEN

15. Who is that with a neck and no head, two
arms and no hands? What is it?
___I_T

22. 01
CORRECT
ELECTRODE
SIZE

23. Larger diameter electrodes are
used on thicker metals and for
flat position welding because
they offer higher deposition
rates.

24. Smaller diameter electrodes are used for
horizontal, vertical and overhead welding,
because they produce a smaller weld
puddle that is easier to control than the
bigger puddle produced by larger diameter
electrodes

25. Joint design also affects electrode diameter.
On groove welds for example, the electrode
has to be small enough to access the root of
the joint. He welder’s skill also has a bearing
on electrode diameter because a more capable
welder can control a larger, more fluid weld
puddle.

27. 02
CORRECT
CURRENT

28. • A volt is the unit of electric
potential difference. Another
way to explain volt is the force
that sends electrons through
an electrical circuit to
establish an electric current
that’s measured in amperes.
• An ampere is the unit for
electric current, which is the
number of electrons flowing
through a circuit.

29. FOR YOUR ACTIVITY!
I will need a volunteer from the
class to perform this activity.
Using a core wire, I will give you
3 scenarios which you will
perform to weld the core wires,
while the rest of the class will
write down an observation.

30. OBSERVATIONS
WHAT HAVE YOU OBSERVED FROM YOUR
ACTIVITY?

31. FOR YOUR PERFORMANCE
I HAVE PREPARED HERE CORRUGATED BARS
FOR YOUR PERFORMANCE. YOU WILL ONLY
WELD THE TWO BARS TOGETHER USING
CORRECT ELECTRODE SIZE AND CORRECT
CURRENT. EACH ONE OF YOU WILL
PERFORM THIS ACTIVITY AND I WILL GIVE
YOU 5-10 MINUTES EACH STUDENT.

32. CRITERIA 5 points 4 Points 3 points 2 points
ACCURACY
Follows the correct
electrode size and
correct current
Follows correct
electrode size but
incorrect current.
The joints are
connected but with
incorrect current
settings..
Both electrode size and
current settings are incorrect
as well as welding technique.
SPEED
Finished in the activity
on time.
Finished the activity 1
minute after the time
allotted.
Finished the activity 2
minute after the time
allotted
Finished the activity 3 minute
after the time allotted
STURDINESS
The joints are properly
welded and can
withstand breaking
force.
The joints are properly
welded but with slight
imperfection.
The joints are not
properly welded and
can’t withstand force.
The welded joints breaks
easily after using chipping
hammer.
SAFETY
Demonstrate the
proper use of PPE. Use only 3 PPE while
working.
Use only 2 PPE while
working.
Use only 1 PPE while
working.
YOU WILL BE GRADED USING THIS CRITERIA:

33. LET'S HAVE A QUIZ
DIRECTION : WRITE TRUE IF THE STATEMENT IS CORRECT
AND FALSE IF THE STATEMENT IS WRONG.
1. The electrode melts too fast if the current settings is too
high.
2. Ampere is the unit of measurement for current.
3. A volt is the unit of electric potential difference.
4. Amperage ranges are usually specified in the welding
procedure or in the manufacturers’ data sheets.
5. Joint design also affects electrode diameter.

34. FOR YOUR ASSIGNMENT
KINDLY BRING YOUR
MATERIALS TOMORROW
FOR THE CONTINUATION
OF YOUR INDIVIDUAL
PERFORMANCE.
