4-4.1.10.1.1 Flat Position Longitudinal Welds in Pipe 2-7/8 Inches OD and Greater, and Flat Position Girth Welds in Pipe Over 24 Inches OD. These welds are qualified by any pipe weld test within the normal thickness limits of table 7-6 (see table 7-6, footnote 13(d)). These welds may also be qualified using plate per 4-4.1.10.2. If plate is used for qualifying flat position girth welds in pipe over 24 inches OD, torch offset remains an essential element per table 7-5. 4-4.1.10.2 Plate. A qualification test assembly weld of sufficient length to provide the required test specimens shall be made in each qualifying position. 4-4.1.10.3 Robotic Welding. Qualification test welds shall be prepared in accordance with 4-4.1.10.1 or 4- 4.1.10.2, as applicable, with the same equipment to be used in production, except as otherwise permitted by 4-7 and 4-8. In addition to the requirements of 4-4.1.10.1 and 4-4.1.10.2, the following shall apply: a. For each cross-qualified welding position (see table 7-4) listed in the welding procedure, an additional level I qualification test assembly shall be welded and subjected to level II testing. For pipe, only the larger diameter test assembly is required in each additional position. b. Groove joints shall not qualify fillet joints. 4-4.1.10.3.1 Automatic Robotic Welding. The following requirements shall also be met for automatic robotic welding: a. Except for single pass fillet welds per 4-4.1.10.3.1.a(5) and similarities per 4-4.1.10.3.1.b, a first article test shall be performed for each production part involving the weld types listed in 4-5.4 that are not 100-percent volumetrically inspected. First article testing shall conform to the following requirements: (1) Pipe shall be treated separately from plate. (2) Test assemblies shall be evaluated in accordance with 4-5.4. (3) A first article test report shall be prepared per 4-6.1.2 and submitted to the authorized representative for review prior to production welding. Approval is not required and production welding may commence upon submittal. (4) First article test data shall be maintained along with the applicable welding procedure. (5) Parts limited to single pass fillet welds are excluded from first article testing. (6) In addition to the requirements of 4-2.1.2, welding of the first article test item shall be performed at the activity’s production facility using the same equipment to be used in production, except as otherwise permitted by 4-7 and 4-8. b. The first article test assembly shall be either a production part or a simulated configuration of the production part (see 3-1.8). A simulated configuration would usually apply for large items such as structural panels, egg crate configurations, foundation assemblies, etc., each of which can differ greatly in size, spacing/arrangement of framing, etc., and for piping assemblies that can have many different shapes, sizes, etc. Use of production parts would usually apply for repetitive smaller components having essentially the same geometry. (1) The simulated configuration of a production part shall, as a minimum, replicate each of the following attributes if the attribute is present in the part: joint type(s) (see 4-5.4); welding position(s); welding position transitions (e.g., horizontal fillet to vertical fillet and vice versa); and generic welding path type(s) (i.e., straight, curved, or end wrap around); for piping, branch-to-run, canted branch-to-run, straight (i.e., run) piping, weld-o-let (i.e., MIL-STD-22 P-68) and ID versus OD welds shall be treated as different attributes, as well as welds in the following different NPS size groups, excluding 1G/1F welds: ≤ 1 -inch; > 1- inch ≤ 3 -inch; > 3- inch ≤ 8 -inch; > 8-inch. (2) A production part or simulated configuration that replicates each attribute (see 4-4.1.10.3.1.b(1)) of another part or simulated configuration that was previously subjected to first article testing, and which contains no additional attributes, shall not require additional first article testing (i.e., differences in parts or simulated configurations based solely on size [except as specified for pipe], qualified thicknesses, number of repeated members, etc., do not require additional first article testing).
