Flux coated metal welding rods

An Arc Welding process that uses flux coated metal electrodes where the burning of the flux produces a protective gaseous cloud around the weld puddle. Often called stick welding

Includes a multitude of welding processes where an electrical arc is used to melt and fuse metal.

The percentage of time a welding machine can operate without overheating, usually based on 10 min.

The measure of the flow/volume of electricity, like the flow of water out of a hose.

Any material that allows the flow of electricity.

Used for household electrical needs, an electrical current that changes its direction of flow many times per second.

Used in automotive applications and rechargeable devices, this current flows in only one direction.

Negative polarity in DC welders, DCEN, results in lower weld penetration, and allows for faster travel.

Positive polarity in DC welders,DCEP, with the current flowing in reverse direction, allows for deeper weld penetration. Usually the "Right" polarity

A spring loaded device with insulated handles for holding welding rods, sometimes called a stinger.

A spring loaded clamp that allows for the welding circuit to be completed during the welding process.

A tool with a striking type head that usually has one pointed side and often a chisel on the other, used for light application in removal of weld slag.

An organization that supports education in welding processes, developed electrode numeric system and weld test standards.

The amount of tension or pull a weld can withstand before failure.

A straight bead or pass made by running the electrode in a straight line without any weaving motion.

Moving the electrode in a particular and continuous pattern to either manipulate the heat input and/or the size of the weld.

The low spot or unfilled end of a weld created by the arc when welding often considered a defect unless used to tie another weld pass into.

A single bead or layer of filler material

The first pass made in a welded joint

Welding downward on a vertical, 3 configuration, piece of metal.

Welding upward on a vertical, 3 configuration, piece of metal.

Portion of the weld that is molten metal while the weld is being made, sometimes called the puddle.

Droplets of molten material created at or near the welding arc, considered a nuisance and undesirable.

In SMAW, this is the coating on the electrode, it protects the weld puddle from the atmosphere preventing weld contamination.

The left-over, melted flux. Often associated with SMAW welding electrodes. Must be cleaned and removed.

Occurs when molten metal flows over the surface of the base metal and cools without fusing with the base metal. An undesirable defect.

A defect, the melting away of the base material at the side wall of a groove weld at the edge of a bead, which produces a sharp recess or hole in the base metal.

A defect caused by a weld being contaminated by unwanted atmospheric gases.

A defect caused by nonmetallic particles becoming trapped in the weld metal or at the weld interface resulting from faulty welding technique or poor weld preparation

Stands for Gas Metal Arc Welding, an arc welding process commonly called MIG welding, were a continuous were electrode is used for melting and fusing metal with a shielding gas protecting the weld.

A small temporary weld made to hold parts of a weldment in place until the final weld is made

The metal that is to be joined by a welding process

The direction of the flow of electrical current in a DC welding circuit.
