The arc welding

With a temperature of up to 3000° C, arc welding is ideal for assembling or repairing steel parts. The metal is thus melted and the two welded pieces become one.

Difficulty level:

Way

Tools and materials needed:

Gloves and a protective mask adapted
Special welding safety glasses
A protective mask adapted for your face
A cotton blouse
A welding machine
Clamp vice
Electrodes
A hammer to stitch
A wire brush
A grinder
A file

For your safety, it is imperative never to look at the electric arc with the naked eye and not to weld with contact lenses. Be sure to work in a room where sparks are not likely to ignite.

Step 1: preparing the material

Start by thoroughly cleaning the parts to be welded to remove rust, dust and paint.
Place the pieces to be welded edge to edge and then assemble them together with the vise clamp to prevent them from moving during welding.

Step 2: start the arc

Arc welding: how to weld well: welding


Choose the appropriate electrode for your work, then put it in the electrode holder for your welding machine.
Turn on the device, making sure to choose the correct intensity (220 or 380 volts)
Rub the end of the electrode against the parts to be welded. You will create sparks that will start the arc. Then move the electrode a few millimeters apart for the arc to form.

Step 3: make the weld

Tilt the electrode to 60 degrees then move it to the top (a few millimeters) of the elements to be welded to achieve a weld seam. The length of your arc should be almost identical to that of the electrode diameter.
Once welded, allow the cord to cool down and do not touch it, as its temperature is very high.

Step 4: the finishes.

Wait for the impurities (called the slag) left by the solder to solidify and then remove this layer with a hammer and wire brush.
If necessary, regularize the surface on the grinder.
When all of your work is done, remove the protective equipment.
