Work
In order to be performed current must flow through the conductors in a closed electrical circuit.
Amperage
The flow of water in a pipe is to electricity
SMAW Parts
A Power source
A ground cable or clamp
An electrode Cable
A welding electrode and electrode holder
The workpiece
Open Circuit Voltage
The voltage present when the welding machine power switch is in the ON position, but no welding is taking
place. It is at is maximum.
,5532°C - 6632°C
The heat generated as the current crosses the arc from the electrode to the workpiece.
The weld deposit is made up of metal from where
As the electrode melts (5532°C - 6632°C) the parent metal and the electrode small particles of molten metal
are carried across the arc stream and deposited in the molten pool on the parent metal.
Mixture of the electrode and the parent metal.
A mix of the melted electrode and the melted parent ,metal
Parent Metal
Metal in the workpiece directly beneath the arc.
Penetration
The force of the arc digs into the workpiece and provides the necessary depth of _______________ for the weld.
,Flux
Covers the SMAW Electrode
Electrodes
Core of solid metal wire or a metal tube containing metal powder. The core conducts the current to the arc
and also provides filler metal for the weld joint.
Filler
Is deposited as the electrode is gradually consumed and the welder moves the arc over the workpiece (at the
correct arc length and travel speed)
Coating (Flux)
Helps keep the arc stable and concentrated. As the chemicals in the coating are vaporized they provide
shielding required to protect the molten metal from contamination by atmosphere.
, Power Source
May supply either DC or AC and have controls so the current can be varied in order to meet the requirements
of different welding tasks, materials and positions.
