in our everyday life?
Types of Wire Joints &
Splices
WESTERN UNION SHORT
TIE
is formed by twisting
tightly the two ends of a
wire together. Next, use
needle-nose pliers to
twist both ends tightly at
least five turns
RAT TAIL JOINT
is made by
connecting two or
more wires and
wrapped them
symmetrically in a
common axis.
KNOTTED TAP JOINT
is made by connecting
a branch wire to a
continuous wire. Take
out about 1 inch of
insulation from the
main wire and 3 inches
from the branch wire
FIXTURE JOINT
This joint need five
inches of insulation
stripped off the wire.
The wires are twisted
a few times with a pair
of pliers for the joint
to be tight.

Soldering
Soldering is a process in which two or
more items are joined together by
melting and putting a filler metal into the
joint (usually solder or soldering lead)
the filler metal having a lower melting
point than the adjoining metal.
Soldering Process
This just means that the two
pieces of metal that you are
joining together, fit as closely as
possible.
STEP ONE: GOOD FIT
• Clean Metal- Sandpaper is also an effective
way to clean your metal. It has the added
benefit of taking “the shine” off of your
surfaces. Flux doesn’t flow well on shiny
metal so, abrading your surfaces to be
soldered will help ensure an even coating of
flux.
STEP TWO:
CLEAN METAL/SOLDER/FLUX/HANDS
• Cleaning solder- is pretty easy
if you are using sheet or wire –
you just clean it like sheet
metal. With the wire solder
• Clean Flux- Flux can get contaminated by dipping
your flux brush into the container. After a while,
the bottle will fill up with debris and other
contaminants (like bits of rusting steel from
paintbrushes, bits of charcoal from your soldering
block) and your flux will get dirty. To save you
from having to buy new flux – just because it’s
dirty – use a small, low-walled container to put
your flux in.
The next important information on heat is
that, in order for the solder to flow, you
must heat the metal on both sides of the
join, up to solder flow temperature. If you
heat one side more than the other, the
solder will flow to the “hot side”.
STEP 3: HEAT
Flux aids in soldering and desoldering
processes by removing oxide films
which form on the surface of metals
being soldered.
STEP 4: FLUX
Don’t heat the solder. The solder is one
of the smallest pieces of metal on your
piece. It will melt first but, won’t do
much except (if you heat it enough)
absorb into the metal, maybe start
eating away at the metal, resulting in
pits or melting into a puddle.
1. Explain in 3-5 sentences
the proper way of good
soldering job.
