Brazing Examinations

require visual inspection only, the requirements for

other nondestructive examinations should be deleted

from these paragraphs and from paragraph entitled

"QUALIFICATION OF INSPECTION AND NONDESTRUCTIVE

PERSONNEL."

**************************************************************************

NOTE: Information based on Table II must be

developed and included in each project

specification. Table must clearly define the

systems to be inspected and the type of NDE

required. Revise Table II if required for the

project.

**************************************************************************

[The Government will] [The Contractor shall] perform visual and

nondestructive examinations to detect surface and internal discontinuities

in completed welds, and submit a Non-Destructive Examination (NDE) report

meeting the requirements specified in ASME B31.1. [The Contractor shall

obtain the services of a qualified commercial inspection or testing

laboratory or technical consultant, approved by the Contracting Officer.]

Visually examine welds. Perform [radiographic,] [liquid penetrant,] [or]

[magnetic particle] examination as specified in Table II of this section.

For systems operating at 6894 kPa (gage) 1000 psig or higher, all welds

shall be examined. For high pressure systems operating less than 6894 kPa

(gage) 1000 psig, perform random NDE. When examination and testing

indicate defects in a weld joint, the weld shall be repaired by a qualified

welder. Remove and replace defects as specified in ASME B31.1, unless

otherwise specified. Repair defects discovered between weld passes before

additional weld material is deposited. Whenever a defect is removed, and

repair by welding is not required, blend the affected area into the

surrounding surface, eliminating sharp notches, crevices, or corners.

After defect removal is complete and before rewelding, examine the area by

the same test methods which first revealed the defect to ensure that the

defect has been eliminated. After rewelding, reexamine the repaired area

by the same test methods originally used for that area. Any indication of

a defect shall be regarded as a defect unless reevaluation by surface

conditioning [and NDE] shows that no unacceptable defects are present. The

use of any foreign material to mask, fill in, seal, or disguise welding

defects will not be permitted.

3.4.1.2

Brazing Examinations

The Contractor shall perform brazing examinations.

a.

Visual Examinations

Visually examine all compressed air systems as follows:

(1) Check brazed joint fit-up. Diametrical clearances shall

conform to brazing procedure requirements.

(2) Check base material of pipe and fitting for conformance to

the applicable drawing or specification.

(3) Check grade of brazing alloy for conformance to the brazing

procedure before fit-up or brazing.
