3. Arc Welding
 welding is a joining process of two or more similar or dissimilar
with or without application of heat, pressure & filler material.
 Arc welding is a welding process that is used to join metal to
metal by using electricity to create enough heat to melt metal,
and the melted metals when cool result in a binding of metals.

4. Arc Welding working
 It is a type of welding that uses a welding power supply to create an
electric arc between a metal
 The stick(electrode) and the base material to melt the metals at the
point of contact arc welders can use either DC or AC current and
consumable or non consumable electrods.

5. salt water Arc Welding
 The welding in which Arc produced with the help of salt
water called salt water welding.
 Salt water solution act as an electrolyte solution.
 the salt water work as a variable resistance or ballast to
control the amperage.

6. salt water weldingprinciple
 Salt water welding based on the principle of electrolyte
solution behaviour of salt water.
 The salt water work as a variable resistance or ballast to
control the amperage.
 The salt water cuts voltage at a greater rate than current.
The resistance will be decrease.
 NaCl Na+ CL-
 the electrons moves towards
anode at high velocity and ions
move towards cathode

7. Step 1: High Amperage! Careful Is Just the Beginning!
This project uses High Amperage and High Voltage and its mostly lethal if not
handed carefully, always wear gloves and shoes, don't operate exposed parts or
not securely insulated components, if you need to change the positions of the
cables inside the water, unplug it first.
Use all the recommended welding equipment when working on this project
including: Welding Glasses or Mask, Leather Gloves, Leather clothes and an
insulated surface. Don't forget to be dry (always dry your hands if you change
anything on the water).
So Its done carefully.

8. Step 2: Materials
Materials
1. 5mm wire(cu)
2. 10L of water
3. 0.5Kg of salt
4. Electrode holder
5. Earth clamp
6. 6013 or 6011 Welding rods or electrode
working steps

9.  step 3: Cut the Wires
 First we are going to need 3 pieces of wire, take the 10m piece and cut it
in half, next take one of these half's and cut in half again.
 Now we got 3 pieces of wire:
1. 5m piece
2. 2.5m piece
 Take the 5m piece, scrape about 1,5cm on each side of the cable, it will be
used as the ground wire. Take the 2,5m cable and scrape 1,5cm on one end
and 20cm on the other end, these will be our positive wire.

10. step 4: Install the Contacts
Now Install the Electrodes
holder on the 1, 5cm end
of the 2,5m cable, and the
earth clamp on one of the
1 ,5cm end of the 5m cable.

11. step 5: All goes into the water
working steps

12.  Fill the 20l gallon with around 15l of water, put the
20cm end of the 2,5m cables in the water and put
something on the bottom to hold them submerged
and straight. Pour around 500g to 800g of salt on the
water.
The salty water will work as a variable resistor,
powering the AMPs up based on Electrolysis.
working steps

13.  Step 6: Plug and Arc
 To turn the power on, Attach the 5m cable on the neutral line of your wall
plug and the 2,5cm cable on the Positive line, “DON'T PUT THEM AS
YOU WISH, YOU MUST KNOW WHICH ONE IS THE HOT WIRE AND
WHICH ONE IS THE GROUND WIRE”.
 Put the 6013 electrode on the electrodes holder and try striking an arc, if
the amps are too low, put the two cables nearer inside the water, if the
amps are too high, space them from one another.
 “DON'T FORGET TO UNPLUG THE WIRES BEFORE ADJUSTING THE
CABLES”.
working steps

14. 1. Easily made.
2.Low cost.
3. In Emergency, it can made at home easily.
4. It works on general line voltage like 230/110v.
5. Heat generation equal on both cathode and anode
6. Work on medium penetration depth.
7. Works on dirty metal
advantage

15. 1. Safety equipment required
2. It may be short circuit.
3. As high current..it will be more dangerous.
4. Lower efficiency.
5. High skill level – operators.
limitations

16.  Finally we can weld through salt water.
 Some time at home, we can weld in emergency.
