Ding Testing Inspection: Welding Process Qualification Expert, Ensuring the Heritage of Welding Quality in Industrial Structures
Welding process qualification testing is a systematic evaluation of the correctness, rationality of welding processes, and the quality of welds to ensure the safety and reliability of welded structures. Ding Testing Inspection provides welding process qualification testing services to professionally assess welding quality and ensure that the performance of welded structures meets international standards, safeguarding industrial safety.
Service Introduction
A complete set of welding process qualification documentation should include:
- Qualification task dispatch instructions
- Qualification task order
- Qualification numbering method
- Weldability evaluation data (or welding process design data)
- Qualification process plan
- Detailed records of the test piece fabrication process
- Qualification inspections
- Original reports of tests, inspections, and trials
- Qualification process report
- Qualification review report, etc.
During the welding process development, approximately 16 documents or records are required (possibly more depending on specific requirements): pre-welding procedure, processing records, welding records, external inspection records, X-ray inspection reports, heat treatment records, tensile test reports, bending test reports, notch test reports, impact test reports, chemical analysis test reports, metallographic test reports, hardness test reports, SSC reports, HIC reports, and welding process qualification reports.
There are a total of 12 or more inspection items: appearance, X-ray inspection, tensile test, bending test, notch test, impact test, chemical analysis, metallography, hardness testing, SSC, HIC. Among these, SSC and HIC tests are the most time-consuming, requiring 720 hours and 96 hours, respectively.
Industry Pain Points
- Numerous inspection items: Approximately 16 documents or records need to be inspected, with complex processes and long duration.
- Some inspection items are time-consuming: SSC and HIC tests require 720 hours and 96 hours, respectively, affecting project progress.
