2.2.7. When surface roughness for thermally cut edges surfaces does not meet the limitations in 2.2.6, how is the surface repaired?

Roughness exceeding the criteria in 2.2.6 and notches not more than 3/16-in. deep should be removed by machining or grinding and fairing-in at a slope not to exceed 1:10. The repair of notches or gouges greater than 3/16-in. deep by welding should be permitted. The following criteria are recommended:

  1. The discontinuity should be suitably prepared for good welding.
  2. Low-hydrogen electrodes not exceeding 5/32-in. diameter should be used.
  3. Other applicable welding requirements of AWS D1.1 should be observed.
  4. The repair should be made flush with the adjacent surface with good workmanship.
  5. The repair should be inspected to assure soundness.
