1. SCOPE

1.1 Scope. This document contains the requirements for the qualification of welding and brazing procedures, welders, welding operators, brazers and brazing operators that must be met prior to any production fabrication. It includes manual, semiautomatic, automatic and machine welding and brazing of ferrous, nonferrous, and dissimilar metals. The qualification tests required by this document are devised to demonstrate the adequacy of the welding or brazing procedures and to demonstrate the ability of welders, brazers, welding operators and brazing operators to produce sound welds or brazes.

1.2 Except as required by 1.2.1, procedures and personnel previously qualified to earlier revisions of this document, for which records are available and qualifications have been maintained, are acceptable for use to this revision.

However, the authorized representative may require requalification to this revision on a case-by-case basis where both of the following apply: (1) he has specific concerns about the adequacy of procedures or ability of personnel to produce welds of intended integrity or which meet requirements of the applicable fabrication document and (2) the existing qualification requires requalification by this document. These requirements also apply to the visual inspection training of personnel required by this document. It is not the purpose of this document to require extensive requalification of previously qualified procedures or personnel. Changes to existing procedures and procedure and personnel qualifications, and qualification of new procedures and personnel performance shall be accomplished in accordance with the requirements of this document.

1.2.1 Procedures involving the use of MIL-12018-M2 or MIL-120S-1 elec-trodes previously qualified to other revisions of this document are not approved for use when this revision is invoked unless specifically approved by NAVSEA.

1.3 This document contains both mandatory requirements (indicated by the word "shall") designed to serve as standards applicable to methods, materials, and inspection, and guidance information (indicated by either the word "should" or "may"). Guidance information is recommended but is not mandatory.

1.4 For existing welding procedures and personnel qualifications in accordance with NAVSEA 250-1500-1, those qualifications may be used as discussed below in lieu of the qualification requirements of this document, provided the prior qualification is for base and filler materials and welding processes normally allowed by NAVSEA 250-1500-1:

(a) Welding procedure qualification evidence which supports an approved welding procedure in accordance with NAVSEA 250-1500-1 may be considered ap-proved, in lieu of welding procedure qualification evidence required by this document, even though the nondestructive and destructive tests conducted on the qualification test assembly may have differed from those required by this document. In addition to the base and filler materials which this qualification evidence allows to be welded in accordance with this document, base and filler materials allowed by the NAVSEA 250-1500-1 approved welding procedure may also be considered qualified. The welding procedure shall be rewritten, as necessary, to conform to the requirements of this document (e.g., to reflect differences in requalification requirements).

(b) Welding personnel qualifications in accordance with NAVSEA 250-1500-1 may be used in lieu of qualifications in accordance with this document provided personnel are trained on the applicable differences. The extent of qualification shall be as allowed in either document.

3.2 Terms related to welding.

3.2.1 Build-up. Build-up is a surfacing variation in which surfacing metal is deposited to restore base material or weld surface dimensions.

3.2.2 Buttering. Buttering is a surfacing variation that deposits surfac-ing metal on one or more surfaces to provide metallurgically compatible weld metal for the subsequent completion of the weld.

3.2.3 Cladding. Cladding is a surfacing variation that deposits or applies surfacing materials, usually to improve corrosion or heat resistance.

3.2.4 Dissimilar metal welds. Dissimilar metal welds are welds involving two metals which differ sufficiently in metallurgical and physical properties to require special consideration in procedure qualification and inspection (see section 4 for exceptions).

3.2.5 Hardfacing. Hardfacing refers to a surfacing variation in which surfacing metal is deposited to reduce wear.

3.2.6 Internal tube-to-header welds. These are welds between various types of boiler tubes and their respective headers (or drums), such as economizer headers, superheater headers, and so forth. These welds are located on the interior of the header (or drum). Integrity of the tube-to-header connection is usually provided by a combination of welding and rolling the tube.

3.2.7 Keyhole welding. Keyhole welding is a technique in which a concen-trated heat source penetrates completely through a workpiece, forming a hole at the leading edge of the weld pool. As the heat source progresses, the molten metal fills in behind the hole to form the weld bead.

3.2.8 Orifice gas (plasma arc welding and cutting). Orifice gas is the gas that is directed into the torch to surround the electrode. It becomes ionized in the arc to form the plasma, and issues from the orifice in the torch nozzle as the plasma jet.

3.2.9 Oscillation. Defining characteristics:

(a) Amplitude. Amplitude is the distance normal to the direction of welding between the outermost positions which the electrode tip reaches while oscillating.

(b) Dwell. Dwell is the time during which the electrode rests at any point in each oscillating swing or traverse.

(c) Frequency. Frequency is the number of complete cycles made by the oscillating head in 1 minute, or other specified time increment.

3.2.10 Seal weld. Seal weld is a weld provided for a fluid containment function only, as in a closure where strength is provided by a separate device.

3.2.11 Socket weld. Socket welds are MIL-STD-22, P-13, -14, -15, -16, -17, -42 and -80 joint design welds in pressure containing piping.

12 Original

3.2.12 Special welds. Special welds are welds involving:

(a) Base materials not covered in table I of this document.

(b) Filler materials not covered in table II of this document.

(c) Material thickness above those specified in table VI of this document or

(d) Processes which are not specified in table III of this document.

3.2.13 Surfacing. Surfacing is the application by welding, brazing, or thermal spraying of a layer of material to a surface to obtain desired properties or dimensions, as opposed to making a joint. (See also buildup, buttering, cladding and hardfacing.)

3.2.14 Tube-to-tubesheet weld. Welds between tubing (usually heat transfer tubing) and the respective tube sheet usually occurring in some type of heat exchanger (see also 3.2.6).

3.2.15 Welding speed (travel speed). Welding speed is the rate of progres-sion of the welding arc along the weld axis.

3.2.16 Wire feed angle. Wire feed angle is the angle between the filler metal and the tangent to the pipe or plate surface at the arc.

3.2.17 Wormhole porosity. Wormhole porosity refers to gas inclusions having an elongated form known as "wormholes" or "pipes" usually oriented almost perpendicular to the weld surface.

3.3 Terms related to brazing.

3.3.1 Brazement. Brazement is an assembly whose component parts are joined by brazing.

3.3.2 Clearance. Clearance is the actual gap at room temperature prior to brazing for capillary flow of filler metal.

3.3.3 Manual torch brazing. Manual torch brazing is torch brazing with the brazer controlling the torch with his hands.

3.3.4 Mechanized torch brazing. Mechanized torch brazing is torch brazing with an automatic or mechanical method of controlling the torch while brazing.

3.3.5 Peel test. Peel test is a destructive method of inspection where a lap joint is mechanically separated by peeling (see figure 20).

3.3.6 Preplaced brazing alloy. Preplaced brazing alloy is any form (shims, wire, rings, and so forth) of brazing alloy which is placed in a joint prior to brazing.
