acetoneA flammable, volatile liquid used in acetylene cylinders to dissolve and stabilize acetylene under high pressure. 
English
acetyleneA highly combustible gas composed of carbon and hydrogen. Used as a fuel gas in the oxyacetylene welding process. 
English
actual throatSee THROAT OF FILLET WELD. 
English
air-acetyleneA low temperature flare produced by burning acetylene with air instead of oxygen. 
English
air-arc cuttingAn arc cutting process in which metals to be cut are melted by the heat of the carbon arc. 
English
alloyA mixture with metallic properties composed of two or more elements, of which at least one is a metal. 
English
alternating currentAn electric current that reverses its direction at regularly recurring intervals. 
English
ammeterAn instrument for measuring electrical current in amperes by an indicator activated by the movement of a coil in a magnetic field or by the longitudinal expansion of a wire carrying the current. 
English
annealingA comprehensive term used to describe the heating and cooling cycle of steel in the solid state. The term annealing usually implies relatively slow cooling. In annealing, the temperature of the operation, the rate of heating and cooling, and the time the metal is held at heat depend upon the composition, shape, and size of the steel product being treated, and the purpose of the treatment. The more important purposes for which steel is annealed a 
English
arc blowThe deflection of an electric arc from its normal path because of magnetic forces. 
English
arc brazingA brazing process wherein the heat is obtained from an electric arc formed between the base metal and an electrode, or between two electrodes. 
English
arc cuttingA group of cutting processes in which the cutting of metals is accomplished by melting with the heat of an arc between the electrode and the base metal. See CARBON-ARC CUTTING, METAL-ARC CUTTIING, ARC-OXYGEN CUTTING, AND AIR-ARC CUTTING. 
English
arc lengthThe distance between the tip of the electrode and the weld puddle. 
English
arc voltageThe voltage across the welding arc. 
English
arc weldingA group of welding processes in which fusion is obtained by heating with an electric arc or arcs, with or without the use of filler metal. 
English
arc-oxygen cuttingAn oxygen-cutting process used to sever metals by a chemical reaction of oxygen with a base metal at elevated temperatures. 
English
as weldedThe condition of weld metal, welded joints, and weldments after welding and prior to any subsequent thermal, mechanical, or chemical treatments. 
English
atomic hydrogen weldingAn arc welding process in which fusion is obtained by heating with an arc maintained between two metal electrodes in an atmosphere of hydrogen. Pressure and/or filler metal may or may not be used. 
English
austeniteThe non-magnetic form of iron characterized by a face-centered cubic lattice crystal structure. It is produced by heating steel above the upper critical temperature and has a high solid solubility for carbon and alloying elements. 
English
axis of a weldA line through the length of a weld, perpendicular to a cross section at its center of gravity. 
English
back fireThe momentary burning back of a flame into the tip, followed by a snap or pop, then immediate reappearance or burning out of the flame. 
English
back passA pass made to deposit a back weld. 
English
back upIn flash and upset welding, a locator used to transmit all or a portion of the upsetting force to the workpieces. 
English
back weldA weld deposited at the back of a single groove weld. 
English
backhand weldingA welding technique in which the flame is directed towards the completed weld. 
English
backing stripA piece of material used to retain molten metal at the root of the weld and/or increase the thermal capacity of the joint so as to prevent excessive warping of the base metal. 
English
backing weldA weld bead applied to the root of a single groove joint to assure complete root penetration. 
English
backstepA sequence in which weld bead increments are deposited in a direction opposite to the direction of progress. 
English
bare electrodeAn arc welding electrode that has no coating other than that incidental to the drawing of the wire. 
English
bare metal-arc weldingAn arc welding process in which fusion is obtained by heating with an unshielded arc between a bare or lightly coated electrode and the work. Pressure is not used and filler metal is obtained from the electrode. 
English
base metalThe metal to be welded or cut. In alloys, it is the metal present in the largest proportion. 
English
bead weldA type of weld composed of one or more string or weave beads deposited on an unbroken surface. 
English
beadingSee STRING BEAD WELDING and WEAVE BEAD. 
English
bevel angleThe angle formed between the prepared edge of a member and a plane perpendicular to the surface of the member. 
English
blacksmith weldingSee FORGE WELDING. 
English
block brazingA brazing process in which bonding is produced by the heat obtained from heated blocks applied to the parts to be joined and by a nonferrous filler metal having a melting point above 800 ºF (427 ºC), but below that of the base metal. The filler metal is distributed in the joint by capillary attraction. 
English
block sequenceA building up sequence of continuous multipass welds in which separated lengths of the weld are completely or partially built up before intervening lengths are deposited. See BUILDUP SEQUENCE. 
English
blow holesee GAS POCKET. 
English
bondThe junction of the welding metal and the base metal. 
English
boxingThe operation of continuing a fillet weld around a corner of a member as an extension of the principal weld. 
English
braze weldingA method of welding by using a filler metal that liquifies above 450 ºC (842 ºF) and below the solid state of the base metals. Unlike brazing, in braze welding, the filler metal is not distributed in the joint by capillary action. 
English
brazingA group of welding processes in which a groove, fillet, lap, or flange joint is bonded by using a nonferrous filler metal having a melting point above 800 ºF (427 ºC), but below that of the base metals. Filler metal is distributed in the joint by capillary attraction. 
English
bridgingA welding defect caused by poor penetration. A void at the root of the weld is spanned by weld metal. 
English
bucklingDistortion caused by the heat of a welding process. 
English
buildup sequenceThe order in which the weld beads of a multipass weld are deposited with respect to the cross section of a joint. See BLOCK SEQUENCE. 
English
butt jointA joint between two workpieces in such a manner that the weld joining the parts is between the surface planes of both of the pieces joined. 
English
butt weldA weld in a butt joint. 
English
butter weldA weld caused of one or more string or weave beads laid down on an unbroken surface to obtain desired properties or dimensions. 
English
capillary attractionThe phenomenon by which adhesion between the molten filler metal and the base metals, together with surface tension of the molten filler metal, causes distribution of the filler metal between the properly fitted surfaces of the joint to be brazed. 
English
carbide precipitationA condition occurring in austenitic stainless steel which contains carbon in a supersaturated solid solution. This condition is unstable. Agitation of the steel during welding causes the excess carbon in solution to precipitate. This effect is also called weld decay.
