Welding Glossary


 * Wandering Sequence ** - A longitudinal sequence in which the weld bead increments are deposited at random.


 * Weave Bead ** - A type of weld bead made with transverse oscillation. (2) ** Weave Bead ** - A welding pattern often used in butt welds where the welder moves the arc back and forth across the joint while also moving along it.


 * Weld ** - A localized coalescence of metals or nonmetals produced either by heating the materials to suitable temperatures, with or without the application or pressure, or by the application of pressure alone, and with or without the use of filler material. ( 2) ** Weld ** - To join two pieces of metal together permanently by melting the parts that touch.


 * Weld Bead ** - A weld deposit resulting from a pass. See stringer bead and weave bead.


 * Weld Crack ** - A crack in weld metal.

Welders Flash - also called "arc eye", "arc burn"


 * Weld Gage ** - A device designed for checking the shape and size of welds.


 * Weld Metal ** - The electrode and base metal that was melted while welding was taking place. This forms the welding bead. (2) **Weld Metal** - That portion of a weld which has been melted during welding.

**Weld Metal Area** - The area of the weld metal as measured on the cross section of a weld.

**Weld Transfer** - Method by which metal is transferred from the wire to the molten puddle.


 * Weldment ** - An assembly whose component parts are joined by welding.


 * Weldability ** - The capacity of a material to be welded under the fabrication conditions imposed into a specific, suitably designed structure and to perform satisfactorily in the


 * Welder ** - One who performs a manual or semiautomatic welding operation. (Sometimes erroneously used to denote as welding machine.) (2) ** Welder (noun) ** - A person whose job is welding.


 * Welder Certification ** - Certification in writing that a welder has produced welds meeting prescribed standards.\


 * Welder Performance Qualification ** - The demonstration of a welder’s ability to produce welds meeting prescribed standards.


 * Welder Registration ** - The act of registering a welder certification or a photostatic copy thereof.


 * Welding ** - A materials joining process used in making welds. (See the Master Chart of Welding and Allied Processes).


 * Welding 10 **


 * Welding Current ** - The current in the welding circuit during the making of a weld.


 * Welding Cycle ** - The complete series of events involved in the making of weld.


 * Welding Fume Hazards**


 * Welding Generator ** - A generator used for supplying current for welding.

 * Welding Head ** - The part of a welding machine or automatic welding equipment in which a welding gun or torch is incorporated.


 * Welding Leads ** - The work lead and electrode lead of an arc welding circuit.


 * Welding Machine ** - Equipment used to perform the


 * Welding Operation ** . For example, spot welding machine, arc welding machine, seam welding machine, etc. - **Welding Operator** - One who operates machine or automatic welding equipment.


 * Welding Personal Protective Equipment**


 * Welding Power Supply ** - A device that provides an electrical current to perform welding.


 * Welding Procedure ** - The detailed methods and practices including all joint welding procedures involved in the production of a weldment. See joint welding procedure.


 * Welding Process ** - A materials joining process which produces coalescence of materials by heating them to suitable temperatures, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler metal. (See the Master Chart of Welding and Allied Processes).


 * Welding Rectifier ** - A device in a welding machine for converting alternating current to direct current.


 * Welding Rod ** - A form of filler metal used for welding or brazing which does not conduct the electrical current. (2) ** Welding Rod ** - A means of delivering filler metal to the weld. In arc welding, the rod is called an electrode.


 * Welding Safety** -


 * Welding Sequence ** - The order of making the welds in a weldment.

Welding Shade Numbers - Guide


 * Welding Technique ** - The details of a welding procedure which are controlled by the


 * Welding Underwater **


 * Wetting. ** The bonding or spreading of a liquid filler metal or flux on a solid base metal.


 * Why Women Live Longer Than Men**


 * Wire Feed Speed ** - Expressed in in/min or mm/s, and refers to the speed and amount of filler metal fed into a weld. Generally speaking the higher the wire feed speed, the higher the amperage. (2) **Wire Feed Speed** - The rate of speed in mm/s* or in./min at which a filler metal is consumed in arc welding. *Note: In Canada this is expressed in mm/min.


 * Wire Straightener ** - A device used for controlling the cast of coiled wire to enable it to be easily fed in to the gun.


 * Women in Welding**


 * Work Angle ** - The angle that the electrode makes with the referenced plane or surface of the base metal in a plane perpendicular to the axis of the weld. See also drag angle and push angle.
 * ** Note ** : This angle can be used to define the position of welding guns, welding torches, high energy beams, welding rods, thermal cutting and thermal spraying torches, and thermal spraying guns.


 * Work Connection ** - The connection of the work lead to the work.


 * Work Lead ** = The electric conductor between the source of arc welding current and the work.

**Work Piece Connection** - A means to fasten the work lead (work cable) to the work (metal to be welded on). Also, the point at which this connection is made. One type of work connection is made with an adjustable clamp.


 * Work Piece Lead ** - The conductor cable or electrical conductor between the arc welding machine and the work.
