WELDING INSPECTION
We have qualified welding inspectors from TWI CSWIP 3.2&3.1
- Review the specifications, referenced codes and standards, field changes and other approved documents such as Procedures, shop/construction drawings, erection drawings, Isometric drawing, P & ID drawing, etc.
- Verify that materials to be welded are the specified grade, type, size, thickness, etc., that required by approved documents for the project.
- Review manufacturer’s material test reports. Welder’s qualification according to (ASME IX).
- Design or approved the welding procedure for each welding type & position acc. to (AWS) procedure Qualification Tests required for non-pre qualified welds and verify that Procedure Qualification Records (PQRs) are compliant with all applicable requirements. (This tests done in locally labs).
- Verify that all welding consumables comply with the approved documents and the approved WPS and verify that all electrodes are properly stored.
- Verify that the electrical characteristic (welding current and voltage) are within the WPS parameters by using a calibrated hand-held volt / amp meter.
- Verify that joint preparation, assembly practice, preheat temperatures, interposes temperatures, welding techniques, welder performance, and post-weld heat treatment meet the requirements of the approved documents, WPS, and applicable code.
- Conduct visual inspection of the work: Verify size, length, and location of all welds. Verify that all welds conform to the requirements of the code and approved documents.
- Mark completed welds, parts, and joints that have been inspected and accepted with a distinguishing mark, tag or dye stamp. The mark shall include: Testing laboratory initials (if applicable), inspector’s initials, inspection date and status.
- Schedule our responsible for nondestructive testing (NDT) technicians in a timely manner, after visual inspection and acceptance is complete.
PIPELINES INSPECTION
- Review Pipeline Design specification and Data Sheet.
- Written or Review Inspection and Quality control plan Inspection Test Plan.
- Inspection of site of transmission pipe track to ensure classification of area, type Construction and safe distance available.
- Inspection of Maximum and minimum depth of the pipeline, Slope angle, Depth of ditching, Distance of maximum span to be supported, Right of way (ROW).
