2.
Electric arc welding is a fusion welding process used
to join metals. An electric arc from an AC or DC
power supply creates an intense heat of around
6500°F which melts the metal at the join between two
work pieces.
WHAT IS ELECTRIC ARC WELDING?
3.
Electric arc welding is commonly used to join
materials and is used across a lot of different
industries. The aerospace industry uses arc welding
to manufacture and repair aircraft, join sheeting, and
for precision work.

TYPES OF ELECTRIC ARC WELDING EQUIPMENT:
Welding Machine.
Electrode Holder.
Lead Cable.
Cable Connectors and Lugs.
Chipping Hammer.
Wire wheel brush.
Protective Clothing.
Screen or Face Shield.
WHAT ARE THE EQUIPMENTS OF
ELECTRIC ARC WELDING?
5. WELDING MACHINE
A welding machine is a machine that helps
to assemble or remove metal parts by
melting them with thermal energy. A
welding machine is a useful tool for people
in the welding industry. It produces heat
that helps dissolve the metal to give it a
different shape or combine metal with any
other metal or metal.

6. ELECTRODE HOLDER
An electrode holder is a device used to
hold the welding rod during the welding
process. It is a clamping device that holds
the electrode firmly enough to enable you
to weld in a variety of positions. They are
available in many different sizes and
current capacities.
BACK
7. LEAD CABLE
The electrode cable is your welding lead,
which delivers power to the electrode and
attaches to the electrode holder. In contrast,
the work cable connects to the work clamp,
sometimes erroneously referred to as the
ground cable and clamp. These cables form
a complete circuit for the arc-welding
system to operate under.

8. CABLE CONNECTORS AND LUGS
Welding cable connectors make quick-
connecting lead extensions, repair worn
cable or electrode connections. Connectors
standardize connection types, allowing
users to connect leads to power sources for
improved efficiency. Cable lugs are devices
used for connecting cables to electrical
appliances, other cables, surfaces, or
mechanisms.

9. CHIPPING HAMMER
Chipping hammers are used to clean and
remove slag from welds and can also be
used for boiler scaling applications. The all
steel construction makes this hammer both
solid and strong and features a striking
head with a sharp conical point and a flat
chisel bevelled end.

10. WIRE WHEEL BRUSH
Wire wheel brushes are the workhorses of
this product category, offering great
versatility for many pre-weld, interpass,
and post-weld cleaning jobs. Cup brushes
are good for weld preparation, especially
when you need to clean a larger area or
wide surface.
BACK
11. PROTECTIVE CLOTHING
Welding and cutting can produce hazards
such as sparks, spatter, radiation (infrared,
ultraviolet, and blue light), slag, heat, hot
metal, fumes and gases, and even electric
shock. Since these hazards may cause burns,
injury, or death.

12. SCREEN OR FACE SHIELD
Face shields are used to protect your eyes,
nose, mouth and face from flying objects
and liquids such as dust, debris, metal
cuttings, acids, and saliva.

THE FOUR MAIN TYPES OF ARC WELDING:
Gas Metal Arc Welding (GMAW).
Gas Tungsten Arc Welding (GTAW).
Shielded Metal Arc Welding (SMAW).
Flux-Cored Arc Welding (FCAW).
WHAT ARE THE DIFFERENT TYPES OF
ARC WELDING?
14.
Gas metal arc welding, sometimes referred to by its
subtypes metal inert gas and metal active gas is a
welding process in which an electric arc forms
between a consumable MIG wire electrode and the
work piece metal, which heats the work piece metal,
causing them to fuse.

WELDING
15.
Gas tungsten arc welding (GTAW) uses a non-
consumable tungsten electrode that must be shielded
with an inert gas. The arc is established between the
tip of the electrode and works to melt the metal
being welded. The consumable filler metal is added
either manually or by some mechanized process.

WELDING
16.
Shielded metal arc welding (SMAW), also known as
manual metal arc welding, is a manual arc welding
process that uses a consumable and protected
electrode. As the electrode melts, a cover that
protects the electrode melts and protects the weld
area from oxygen and other atmospheric gases.
BACK
SHIELDED METAL
ARC WELDING
17.
Flux-Cored Arc Welding (FCAW) uses the heat
generated by a DC electric arc to fuse the metal in the
joint area. The arc is struck between a continuously
fed consumable filler wire and the workpiece,
melting both the filler wire and the workpiece in the
immediate vicinity.
