3.5 GOVERNMENT INSPECTION AND TESTING

When the soundness of any weld is suspected of being deficient due to faulty welding or stresses that might occur during shipment or erection, the Government reserves the right to perform nondestructive supplemental examinations before final acceptance to the extent determined by the CO.

The costs of such inspection and testing will be borne by the Contractor if unsatisfactory welds are discovered, or by the Government if the welds are satisfactory. The work may be performed by the Government's own forces or under a separate contract for inspection and testing.

3.6 CORRECTIONS AND REPAIRS

3.6.1 Welded Joint Repair

If inspection or testing indicates defects in the weld joints, repair defective welds using a qualified welder or welding operator as applicable.

Defects caused by shipping and handling or due to latent defects that were not caught at shop inspection must be corrected at the Contractor's expense inclusive any shipping costs. Make corrections in accordance with the requirements of AWS D1.1/D1.1M, the approved repair procedures, and the specifications. Repair defects discovered between passes before additional weld material is deposited. Wherever a defect is removed and repair by welding is not required, blend the affected area into the surrounding surface to eliminate sharp notches, crevices, or corners. After a defect is thought to have been removed, and before re-welding, examine the area by suitable methods to ensure that the defect has been eliminated. Repaired welds must meet the inspection requirements for the original welds.

3.6.2 Heat Straightening

When steel weldments are warped during fabrication, or due to shipping and handling, and do not conform to dimensional requirements then the weldments must be repaired or replaced at no additional cost to the Government.

Straighten material without shearing, fracturing, stressing, or damaging bolts, welds, or base metal. Do not heat straighten the metal unless allowed by the Engineer of Record. If allowed and before performing any straightening operations, submit a Heat Straightening Procedure to the engineer for review and approval for any application where heat may be applied to correct or remedy dimensions. Do not heat metal to temperatures greater than 1000 degrees F. The use of cutting heads will not be permitted for heating and straightening. After heating and straightening, allow the metal to slowly cool in still air to ambient before inspecting for evidence of fracture or other damage. Replace material damaged during straightening operations with new material at no additional cost to the Government. If the Engineer determines it is not acceptable to straighten a weldment or a member of that weldment, remove the bent material from the assembly, straighten, and re-assemble, or replace the weldment, as required.

3.7 Discontinuity Acceptance In Base Metal

Where discontinuities in steel is observed during fabrication, replace the steel part with the discontinuity.

3.8 PROTECTION OF FINISHED WORK

3.8.1 Steel

Thoroughly clean machined surfaces of foreign matter. Protect all finished surfaces by suitable means. Oil and wrap unassembled pins and bolts with moisture resistant paper or protect by other approved means. Wash finished surfaces of ferrous metals to be in bolted contact with an approved rust inhibitor and coat with an approved rust resisting compound for temporary protection during fabrication, shipping and storage periods.

3.8.2 Shipping and Handling

Protect material from dirt, oil, and other foreign matter. Protect material so that water is not permitted to collect and pool. Employ handling methods that do not result in distortion or other damage to components during fabrication, assembly, loading, shipment, and unloading of components.
