ARC: Describes a term used in welding that refers to the flow of electricity running through the air generating high temperatures.
ARC BLOW: Describes a welding term that refers to the tendency for an arc to deviate from its ordinary course during arc welding due to changes in a magnetic field.
ELECTRICAL ARCING: Describes a fault that often occurs in paint spraying when the spray gun is not moved along the panel surface at a uniform distance leading to an uneven application of paint.
ARC WELDING: Describes a welding procedure in which an electric current is employed to melt both the metal to be welded and the welding rod or electrode being added.
AUTOMATIC ARC WELDING: Describes a process of arc welding carried out by a welding machine capable of automatically moving the arc along the joint to be welded while feeding the electrode into the arc controlling its length.
AUTOMATIC WELDING: Describes a welding procedure where the item being welded, the torch, and the arc are moved mechanically with the only function of hand controls is to control the speed and the direction of travel.
BACKHAND WELDING: Describes the action of welding in the direction opposite to where the gas flame is pointing.
BEAD: Describes the appearance of the finished weld, taking in the orderliness of the ripples formed by the metal while it was in a semi-liquid state.
BRAZE WELDING: Describes the act of making an adhesion groove, fillet, or plug connection with a brazing alloy
CONTINUOUS WELD: Describes the system of completing a weld in a single operation.
CONVEX WELD: Describes a weld with the face above the weld edges.
COVERED ELECTRODE: Describes the type of metal rod used in arc welding that has a covering of materials to aid in the arc welding process.
CRATER: Describes a depression in the face of a weld, usually at the termination of an arc weld
ELECTRIC WELDING: Describes the function of welding using an electrical current to melt both meta and welding rod or electrodes.
ELECTRODE: Describes the metal rod that is used in arc welding that brings electricity up to the point where the arc is to be formed; In electric arc welding, the electrode is usually melted and becomes a part of the weld.
FACE OF WELD: Describes the exposed surface of a weld.
FILLET: Describes a weld metal in the corner of an angle that is formed by two pieces of metal, giving the joint additional strength to withstand unusual stresses.
FILLET WELD: Describes metal that has been fused into a corner formed by two pieces of metal whose welded surfaces are approximately 90° to each other.
FLAME CUTTING: Describes metal cutting when performed by an oxygen-fuel gas torch flame with an oxygen jet.
FLAME FRONT: Describes certain aspects of fuel explosion in cylinders. The flame front should move in a controlled pattern across the cylinder rather than immediately exploding.
FLAT POSITION WELDING: Describes the process of creating a horizontal weld on the upper side of a horizontal surface.
FLUTE: Describes a groove in a cutting tool that forms a passageway to allow the exit of chips during the cutting process.
FORWARD WELDING: Describes the action of fusing metal in the same direction as the torch flame points.
FRICTION WELDING: Describes a type of weld in which the necessary welding heat is generated through revolving one part against another under very heavy pressure.
FUSE: Describes the action of melting when a piece of metal turns to a liquid state and sometimes unites itself to a nearby component.
FUSION: Describes a situation where two metals reach a melting point and begin welding themselves together.
