Quia - Welding Vocabulary Welding Word Searches

Hallo ! Welcome to the a domain all about welder, This a domain was created as a means to provide a variety of information, especially relating to welder actions. this session me will discuss about"Quia - Welding Vocabulary" distinctly, let's go see more...

Quia - Welding Vocabulary

ABAC or Alternating CurrentElectricity that reverses it's direction of electron flow in regular intervalsAcetyleneGas composed to two parts carbon and two parts hydogen, when burned with oxygen, produces on of the highest flame temperatures obtainableAcetylene RegulatorDevice used to control flow of acetylene. Tegulartor reduces acetylene cylinder pressures to torch pressures and keeps pressures constantActual Throatshortest distance from root of weld to face of weldAdhesionAct of sticking or clingingAlloyPure metal that has additional metal or nonmetal elements added while molton.AmpereUnit of electrical current.ArcFlow of electricity through gaseous space or air gapArc blowwanderign of an electric arc from its normal path due to magnetic forcesAxis of weldImaginary line through the center of the weld metal from the beginning to end of weldBackfire'Pop' of torch flame followed by extinguishing the flame or continued burning of gasesBase Metalmetal to be welded, cut or brazedBeadappearance of the finished weldBevelangle cut on edge of base metal in weld to create a grooveBuildupThe amount that the weld face extends above the surface of the base metalButt JointTwo pieces are joined in the same plane, with the edge of one touching the edge of the otherCapillary ActionProperty of liquid to move into small spaces if it has the abiity to 'wet' those surfacesCoalescenceIntermixing or growing together of materials into one body while being weldedCohesionSticking together through attraction of moleculesConcave weld faceA weld with the center of its face below the weld edgesConductivityThe ability of a conductor to carry a currentConductorSupstance capable of readily transmitting electricity or heatConeInner visible flame shape of a neutral or nearly neutral flameConvex weldA weld with the face above the weld edgesCovered electrodeMetal rod used in arc welding, covering materials aid in arc weldingCrownThe curved or convex surface of a finished weldDC or Direct CurrentElectric current that flows only in one directionDepth of fusionDepth to which base metal is melted during weldingDiffusionSpreading of an element throughout a gas, liquid, or solid, so that all of it has the same compositionDiscontinuityAny abrupt change or break (crack, seams, laps, bumps or changes in density) in the shape or structure of a part. The usefulness of that part may or may not be affectedDistortionWarping of a part of a structureDragThe offset distance between the actual and theoretical exit points of the cutting oxygen stream, measured on the exit side of that materialDuctilityThe ability of a material to be changed in shape without cracking or breakingEdge jointA joint between the edges of two or more parallel partsEffective throatOn a fillet weld: the least distance from the root of a weld to the weld faceElectrodeTerminal point to which elecctricity os brought in the welding operation from which the arc is produced to do the welding. Usually melted and becomes part of the weldElectronOne of the fundamental parts of an atom that has a small negative electrical chargeFace of a weldExposed surace of the weldFeed rateSpeed material moves through welding gun in a unit of time (MIG)Filler metalMetal added when making a welded, brazed or soldered jointFillet weldMetal fused into a corner formed by two pieces of metal which are about 90 degrees to each otherFilter plateOptical material that protects eyes from ultraviolet, infrared and visible radiationFlashImpact of eletric arc rays against himan eyesFlashbackburning ack of gases into oxyfuel gas torch, hoses and possibly into regulator and cylinder: VERY DANGEROUS SITUATIONFlashback arrestorCheck valve installed between torch and welding hose to prevent flow of burning gas and oxygen ack into hoses and regulatorsFlay position weldHorizontal weld on upper side of a horizontal surfaceFluxMaterial used to prevent, dissolve, or help remove oxides and other undesirable surface substancesFront viewThe view on a working drawing that shows the greatest amount of detail about an object's shape and sizeFusionIntimate mizing or combining of molten metalsFusion FaceThe surface of the base metal which is melted during weldingGMAWArc welding using a continuously fed comsumable electrode and a shielding gasGTAWArc welding using electrode and a shileding gas. The filler metal is added using a welding rodGroove jointJoint that has one or both edges cut or machined to form a bevel.
