Welding with equipment that performs the welding operation under the constant observation and control of a welding operator. The equipment may or may not load and unload the workpieces. Also called automatic welding.
100
non-ferrous
Refers to a metal that contains no iron, such as aluminum, copper, bronze, brass, tin, lead, gold, silver, etc.
100
overhead position
The position in which welding is performed from the underside of the joint
100
parameters
The welding settings on a welding power supply such as amperage and voltage that are normally read on meters.
100
plasma
– A gas that has been superheated and becomes ionized and conducts current.
200
melting rate
The weight or length of electrode melted in a unit of time.
200
nozzle
A device that directs shielding media.
200
overlap
The protrusion of weld metal beyond the weld toe or weld root.
200
parent metal
– A non-standard term for base metal.
200
.plasma
A gas that has been superheated and becomes ionized and conducts current.
300
microprocessor
A power supply that has pre-programmed instructions to perform specific tasks.
300
nugget
the weld metal joining the workpieces in spot, roll spot, seam or projection welds.
300
overlaying
A non-standard term for surfacing.
300
partial joint penetration
Joint penetration that is intentionally less than complete.
300
plasma arc cutting
(PAC) An arc cutting process that severs metal by melting a localized area with a constricted arc and removing the molten material with a high velocity jet of hot, ionized gas issuing from the constricting orifice.
400
metal electrode –
A filler or non-filler metal electrode used in arc welding or cutting that consists of a metal wire or rod that has been manufactured by any method and that is either bare or covered.

Department of the Navy
What does a Marine check have written on it? Where does it come from
400
oxyfuel gas cutting –
A group of oxygen based cutting processes that uses heat from
an oxyfuel gas flame to bring up to the kindling temperature and helps maintain the cut on steel. Severing of the material is achieved by the oxygen jet, which burns the iron in the steel, that has been heated to kindling temperature by the oxyfuel preheat flames.
400
pass –
Also called weld pass. A single progressions of welding along a joint. The result of a pas is a weld bead or layer.
400
plasma arc welding
(PAW) An arc welding process that produces coalescence of metals by heating them with a constricted arc between an electrode and the workpiece (transferred arc) or the electrode and the constricting nozzle (non-transferred arc). Shielding is obtained from the hot, ionized gas issuing from the torch which may be supplemented by an auxiliary source of shielding gas. Shielding gas may be an inert gas or a mixture of gases. Pressure mayor may not be used, and filer metal mayor may not be supplied.
500
metallic bond
The principal bond that holds metals together and is formed between base metals and filler metals in all welding processes. This is a primary bond arising form the increased spatial extension of the valence electron wave functions when an aggregate of metal atoms is brought close together.
500
Yes
What is the opposite of No?
500
oxyfuel gas welding
A group of welding processes that produces coalescence of workpieces by heating them with an oxyfuel gas flame. The processes are used with or without the application of pressure and with or without filler metal.
500
penetration
A non-standard term for joint penetration and root penetration.
500
plug weld
A weld made in a circular hole in one member of a joint fusing that member to another member. A fillet-welded hole is not to be construed as conforming to this definition.
