SMAW Terms To Know

Weave Bead

A bead has a width up to six times the diameter of the electrode

Arc Welder

A machine that produces current for welding

Generator

A machine that produces direct current

Weldor

A person who welds

Weld Toe

A properly made weld bead with good contour and penetration

Arc Welding

A term to be known as Stick Welding

Electrodes

A unit focuses on a welding process that uses fluxcoating metal welding rods

Arc

An arc is the discharge of electricity through an air space

Stick Welding

An other lack of term of SMAW

Wire Brush

Cleans of slag and cleans metal before and after weld

Transformers

Converts high voltage and low amperage to low voltage and high amperage.

Direct Current (DC)

Flows in one direction only in accordance with how the welder is set

Porosity

From gases trapped inside the weld

60 Cycle Current

In the United States, power plants produce electricity that reverses its direction of flow 60 times per second.

Undercut

Is a depression in the base metal next to the weld toe that is below the surface of the base metal.

Carbon Arc Torch

Is a device that holds two carbon sticks and produces a flame from the energy of an electric welder.

Volt (V)

Is a measure of electrical pressure

Watt (W)

Is a measure of energy available or work that can be done

Ampere (A)

Is a measure of the rate of flow of current in a conductor.

Ground Clamp

Is a spring-loaded clamp attached to an electrical cable

Electrode Holder

Is a spring-loaded device with insulated handles used to grip a welding electrode.

Chipping Hammer

Is a steel hammer with a sharp edge and/or point to remove slag from weld.

National Electrical Manufacturers Association (NEMA)

Is a system to permit manufacturers to mark their electrodes by color codes.

American Welding Society (AWS)

Is an organization of individuals and agencies that support education in welding process.

Conductor

Is any material that permits current to move through it. Copper is a great conductor.

Alternating Current (AC)

Is the Current that reverses its direction of flow frequently.

Reverse Polarity (Positive)

Is the direct current flowing in the opposite direction.

Straight Polarity (Negative)

Is the term given to DC current flowing in one direction

Ground Markings

Most manufacturers simply stamp the AWS classification number on each electrode, rather than using the color-coding system.

Tensile Strength

Refers to the amount of tension or pull the weld can withstand

Polarity

Refers to the direction of flow of electricity in the welding circuit.

Spatter

Samll metal droplets that fall onto the base metal surface surrounding the weld and solidfy. Too long of an arc length causes this.

Wattage

The amount of energy being produced

Arc Blow

The deflection of a welding arc from its normal path because of magnetic forces.

Slag

The flux and impurities float to the top of the weld to form a layer

Drag Angele

The position of the electrode of intended travel

Shielded Metal Arc Welding (SMAW)

The term "shielded" refers to the gaseous cloud formed around the weld by the burning flux.

Whipping Motion

To control the weld puddle when depositing an E6010 electrode stringer bead, use what is known as a

Duty Cycle

is the percentage of time that a welder can operate without overheating the welding machine.
