Consistent peen groove depth.
All weld lengths modified with the TIG toe dress, toe grinding, or ultrasonic peening process shall be visually inspected for acceptance. No visible discontinuities are permitted such as porosity, inclusions, lack of fusion, voids, overlap, and cracks. When the Toe Grinding process is used, reduction in the cross-sectional thickness of the base material shall not exceed 2.0 mm (0.08 inch). A minimum of 3.0 mm (0.12 inch) toe radius for the full length of the treated weld toe is required. A suitable radius gage shall be used to verify the TIG toe dressing (TTD) weld to the minimum radius requirements. Undercut on the TTD weld toes should not exceed 0.5 mm (0.02 inch) in depth. Undercut should be checked with a gage that has a minimum of 0.5 mm (0.02 inch) accuracy. The weld size shall be measured after the manufacturing process of the weld to ensure that throat size was not compromised during the weld toe treatment. Sharp transitions from the TTD to base metal and TTD to the original weld metal are not acceptable.

Arc Length - The distance from the end of the electrode core to the surface of the puddle of molten metal.Arc Stream - Molten particles of electrode material flowing from the electrode to the puddle of molten 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 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
