THE WELDING WORKSHOP

1st YEAR

II CICLE

E.E.T. Nº 16

Metal Arc Welding is the process

of joining tw

o metal pieces

using a flux–coated rod.

Gather the tools

and materials

you will need to begin welding.

And set up a safe

work area.

Here are some of the tools and safety equipment we use in the welding workshop.

We measure the material with the ruler.

We must have the tools at hand and ordered in a logical way.

We remove the slag and clean up the weld with the chipping hammer and the wire brush.

This is a machine tool. It is an electric cicular saw. It is used for cutting metal.

We use these three mechanic tools for cutting and bending the pieces of material.

This is an arc welding machine. It converts 120-240 volt AC electricity to welding

voltage, typically 40-70 volts AC.

The welder must wear safety clothes to prevent the damage of sparks.

Here, the welder is putting on the “welding boots”.

The “welding leathers” is a specially insulated leather apron.

The “welding sleeves” are also made of leather.

The “welding shield” is a mask which is worn to protect the person welding, from the bright flash of the arc and

from sparks being thrown during welding.

The “welding gloves” are insulated leather gloves that reach about six inches above the wrists.

We use a punch to mark the metal surface.

The ground clamp is attached to the work piece. and completes the electrical circuit.

It completes the electrical circuit allowing the electricity to pass through the metal being welded.

The “welding leads” hold the electrode.

After properly fitting the work pieces, strike the arc.

Then move the arc to create a bead.

Chip the weld between passes to remove the slag or the melted electrode flux material.

Then wire brush, so only clean molten metal will fill the weld on the subsequent pass.

Following these simple

steps we will have

the window frame

done in two

weeks work.
