Review of WPSs and PQRs per ITP-35795-1045 Rev 1 Activity Number A5.
Item Inspected: Burner-Windbox Weldment.
Findings: Aspects Reviewed: Due to no effective communication at Vendor Facilities all welds Stainless Steel to Stainless Steel of Windbox Assy have been welded following a Welding Procedure identified as WPS-150.2 with GMAW process, which is not approved by Customer instead of the approved WPS-135A with GTAW process.
Re-Inspection: Vendor has generated a NCR for this non-conformance and per Customer Disposition, has cutted apart all SS Joints of Windbox removing the Weld material applied per the wrong WPS-150.2 by GMAW process and welded again in accordance with approved WPS-135A by GTAW process.
