exit hole. Hole remaining at the end of a weld alter the withdrawal of the tool (see Figure 3.1). Fabricator. The organization responsible for producing weldmenis that satisfy the design and contract requirements. flash. Material expelled along the weld toe during FSW (see Figure 3.4).
heel. Part of the tool shoulder that is at the rear of the tool relative to its forward motion (see Figure 3.5). heel plunge depth. Distance the heel extends into the workpiece (see Figure 3.5).
hook. Faying surface that curves upward or downward along the side of the weld metal in a friction stir welded lap joint and is considered a discontinuity (see Figure 3.6).
incomplete joint penetration. Discontinuity where the full thickness of the joint has not been welded (see Figure 3.7).
iilhitiLIp. A nonstandard term for root opening of a square groove joint.
linear mismatch across joint. Misalignment between two welded pieces such that while their surface planes are parallel, they are not in the required plane (see Figure 3.8).
machine stiffness. The abiijy of a machine to resist deflection when subjected to applied forces. penetration ligament. The nominal distance between the anvil and the probe tip during welding (see Figure 3.1). pipe. Tube in standardized combination of outside diameter and wall thickness.
NOTE: In this specification, the term pipe will be used for pipe and tube.
plate. Rolled, extruded, cast, forged. or deposited products other than pipe in any thickness greater than 0.006 inches [0.152 mm].
NOTE: In this specification, the terimi plate is used to generally describe flat, non-round imietal products other ihait pipe.
plunge depth. Distance tool probe penetrates into the weld joint (see Figure 3.5).
probe. Part of the welding tool that extends into the workpiece to make the weld (see Figure 3.1).
procedure qualification variable. Controllable detail, which, if changed beyond the limitations of the welding procedure specification, requires requalitIcation of the WPS.
Referencing Document. Fabrication code, specification, contract document, or internal document such as the engineering drawing, quality control, or quality assurance manuals, which invoke this specification.
retractable probe FSW. Friction stir welding method in which the probe is axially movable (retractable) inside the shoulder via a secondary linear axis which may also embody an independent rotation drive.
retreating side of weld. Side of the weld where the direction of tool rotation is opposite to the welding direction (see Figure 3.1).
self-reacting FSW. Friction stir welding method in which the anvil is replaced by a root-side shoulder that reacts to the crown-side shoulder load, squeezing the material between the crown-side shoulder and the root-side shoulder (see Figure 3.9).
self-reacting tool. FSW tool with two shoulders separated by a fixed length probe or an adjustable length probe, that is used for the self-reacting FSW method (see Figure 3.9).
tilt angle. The angle in degrees that the tool rotational axis tilts relative to a line peendicular to the workpiece surface in the plane of the weld joint (see Figure 3.5).AWS D17.3-D17.3M  pdf download.
