Introduction to documents in Welding

Welding Process is almost inevitable in all industry , welding process is involved from foundry cast material repair to airspace components .

Stages of Inspection:

• Project Documents
• Incoming Material Inspection
• Cutting Inspection
• Fit – Up Inspection
• WPS, PQR, WQT & Weld Audits
• Weld Visual Inspection
• Dimensional Inspection
• Non Destructive Testing
• Painting Inspection
• Load Tests / Pressure tests
• Final Inspection

Project Documents

• QAP – Quality Assurance Plan
• ITP – Inspection Test Plan
• Approved drawings
• WPS- Welding Procedure Specification / PQR- Procedure Qualification Records
• WQT- Welder Qualification Test records
• NDT – Non destructive testing procedures
• Consumables control procedure
• Fit up and fabrication procedure
• Painting procedure
• Erection procedure

Incoming Material Inspection

• Visual Inspection
• Dimensional Inspection
• Verification of Heat number and Material Test Certificate
• Preparation of Incoming material inspectioon report
• Sample Chemical and chemical test in Lab / per lot
• Storage

Cutting Inspection

• Dimension inspection as per drawing
• Traceability ( heat number )
• Verification of surface preparation in cutting areas.

Fit-up Inspection

• Verification of traceability
• Dimensional check
• Joint preparation inspection ( root face, bevel angle , root gap etc)
• Ensure proper supports and fixtures are provided to avoid distortion
• Fit-up inspection report

WPS, PQR, WQT & Weld Audit

• Verify appropriate WPS is Available
• Verify the qualification for Welders
• Verify consumables control
• Verify the welding parameters followed as per the WPS

Weld Visual Inspection

• Visual Inspection
• Check the temporary supports are removed
• Write down the welder name and WPS number to each and every weld joint number .Make Visual Inspection Report

Final Dimension Inspection

• Check the dimensions ( Length, width, diagonal, height, flatness, angle , etc )

Non Destructive Test Report

• UT, RT, PT, MT, ET or any other

Load Test or Pressure Test

• Load test / pressure test report or pressure test chart

Painting Inspection

• Surface Preparation & Painting Inspection Report

Final Inspection

• Packing report
• Check list / punch list
• Final QC Dossier .
