| Title | Part 21 Report on Welding of Safety Related Components |
| Event Description | SUBJECT: Welder Qualification
PURPOSE: The purpose of this Fisher Information Notice (FIN) is to alert customers that as of November 16, 2007, Fisher Controls International LLC became aware of the possibility of a situation related to welding of safety-related components at the Fisher Controls Marshalltown facility. We are informing our customers of record of this circumstance in accordance with Section 21.21 (b) of 10 CFR 21 because Fisher Controls International LLC is not aware of each and every application or system design utilized by our customers therefore cannot determine whether an anomaly could cause a defect or 'failure to comply', relating to a substantial safety hazard. Receipt of this notice does not necessarily mean that the recipient has been shipped any of the subject equipment. It is expected that the recipients of this notice will review the information for applicability to their facilities, and if required, take the appropriate action as described in the section at the end of this notice. APPLICABILITY: This notice applies only to the subject equipment supplied by Fisher Controls International LLC identified [below]. DISCUSSION: During an internal audit, it was determined that one welder was missing the necessary qualification documentation to weld repair ASME SA351-CF8M or ASME SA479-S31600 (P-No 8) material using ASME SFA-5.4 Grade E316L filler (categorized as an F-No. 5 filler in ASME Section IX), using the shielded metal arc welding (SMAW) process. Fisher has conducted a review of all applicable weld records and compiled a list of all applicable orders, based on a June 2005, date of hire. A Corrective Action Request (CAR) has been initiated to determine root cause and appropriate corrective actions. Fisher has not, as of the date of this notice, found any indication that the valves will not continue to function as designed. In order to support this position. Fisher submits the following facts: - Fisher has determined that all filler material used for these weld repairs were the correct ASME code material. - For pressure boundary parts, weld repaired material successfully completed a production hydro. - Once the issue was discovered, the welder successfully qualified for the missing process and filler combination. Note: Fisher is continuing to investigate. If necessary, updates will be made when more information becomes available. ACTIONS REQURED: No action is required for plants that do not have the subject equipment. If your plant has installed any of the equipment identified by this notice, based on the information gathered to date, Fisher has no reason to believe that the affected parts will not perform their intended valve function. If your plant has not installed any of the equipment identified by this notice, contact your local Fisher Representative Sales Office regarding appropriate corrective action. IMPLICATIONS: The recipient of this notice is requested to review the information contained in this notice to determine its applicability to his/her facility. If no equipment meeting the applicability requirements listed above have been provided by Fisher Controls International LLC, then no further action is required. If equipment meeting the applicability requirements listed above have been supplied and used in a safety-related application, Fisher Controls requests that the recipient of this notice review it and take appropriate action in accordance with 10 CFR 21. The following are the plant sites to which this notice applies: Catawba, Davis-Besse, Oconee, Salem, St. Lucie. |
