Essentials of Welding

The strength of an electric current in amperes.

• voltage

• amperage

• wattage

• current

It is the unit of an electric current.

• ampere

• volt

• ohm

• watt

It is the straight distance between the electrode tip and the job surface when an arc is form.

• arc

• angle

• coating

• length of arc

Is approximately equal to the diameter of the core wire of the electrode.

• normal arc length

• short arc length

• long arc length

• electrode angle

The angle at which you hold the electrode while welding

• Travel angle

• work angle

• drag angle

• electrode angle

Is when the electrode points away the direction of travel.

• travel angle

• work angle

• drag angle

• push angle

Is the linear rate that an arc moves along the workpiece.

• travel angle

• work angle

• push angle

• travel speed

Is the molten metal produced while the weld is being made.

• weld bead

• weld puddle

• weld crater

• weld ripple
