Error Type: | Nicks and Gouges |
Description of Error: | Gouges in cut base metal edges that are 7/16" deep or less, where the surface should be flat. |
Solution Recommended: | If the gouge meets the tolerance of greater
than 3/16" and less than 7/16" from the cut edge, welding with single arc shield metal arc welding (S.M.A.W) is required, If gouge is less than 3/16" deep from the cut edge see below for other solution. |
Required Final Checks / Verification: | If welding is required then magnetic particle testing (M.T.) and/or ultrasonic testing (U.T.) is required. |
Was Repair Successful ?: | Yes. |
Other Possible solutions: | If the gouge is less than 3/16" deep from the cut edge, grinding to a slope of 1 inch to remove the gouge is acceptable. No welding required. |
Remarks: | Preparation is required for welding. (preparation of gouged area includes air-arc gouging or grinding to the bottom of the burn. Preheat is required. These are only if welding is involved) |
