Arc Length - The distance from the end of the electrode core to the surface of the puddle of molton metal. Arc Stream - Molten particles of electrode material flowing from the electrode to the puddle of molton metal. Arc Welding - A process of fusion welding in which the heat from an electric arc is utilized to melt the adjacent surfaces of the pieces to be welded. Axis (of a Joint) - A line through the weld deposit in a joint perpendicular to the cross section at its center of gravity. Back Blow - Deflection of the arc away from the direction of travel. See Magnetic Arc Blow. Back-up Plate - A plate placed behind a wide gap weld joint to retain the molten weld metal and insure complete penetration and fusion at the root of the weld. Base Metal - See Parent Metal. Cold Lap - A void between the weld deposit and the parent metal caused by insufficient fusion. Crater - The depression in a weld deposit caused by displacement of molten weld metal by the force of the arc stream. Depth of Penetration - The distance from the surface of the parent metal to the root of the weld. Electrode Angle - The angle that the electrode makes with the axis of the joint or the surfaces of the weldment members. Flat Position - A joint position where both the axis of the joint and the face of the weld are within 10° of horizontal and the welding is performed on the top of the joint. Flux - Fusible material used in welding to dissolve and facilitate removal of oxides and other undesirable substances. Forward Blow - Deflection of the arc toward the direction of travel. See Magnetic Arc Blow. Fusion - The melting together of parent metal and weld metal. Fusion Welding - Welding by melting the adfacent surfaces of pieces to be joined and allowing the molten metal to mix. Gas Shielding - The protection of molten weld metal from the air with a cloud of gas which is generated by the vaporization of materials in the electrode coating. Gouging - Formation of a chamber or groove by melting and removing a portion of vase metal. Hardsurfacing - The deposition of weld metal on metal surface to obtain desired characteristics or dimensions. Heat Treated Steel - A steel that has been heated, quenched and tempered, or otherwise trated in such a manner that its surface hardness is greater than in the annealed condition. High-Strength Structural Steal - A weldable steel with a minimum yield strength of 45,000 psi and a minimum tensile strength of 70,000 psi. Horizontal Position - A joint position where the axis of the joint is within 10° of horizontal and the face of the weld is between 10° and 90° from horizontal. Interpass Temperature - In a multiple pass weld, the lowest temperature of the weld metal before the next pass is started. Interpass temperature should be
