This Welding Symbols, Wps And Pqr Made Simple spreadsheet from 3D-LABS follows ASME standards and gives instant, checkable results for practising engineers — no manual derivation required.
Welding Symbols, WPS and PQR Made Simple covers welding drawing symbols per ISO 2553:2019 and AWS A2.4-2012, and the complete Welding Procedure Specification (WPS) and Procedure Qualification Record (PQR) documentation process under ASME Section IX, ISO 15614-1:2017, and IS 7307 Part 1. Written for welding engineers, QC inspectors, and fabrication engineers.
What welding symbols and standards are covered?
ISO 2553:2019 symbology: arrow-side vs other-side welds, groove types (V, double-V, U, J), fillet welds (size, length, pitch for intermittent), plug, slot, seam, and spot welds. AWS A2.4-2012 system compared symbol-by-symbol with ISO 2553. For each symbol: the drawing annotation format, joint preparation dimensions (included angle, root gap, root face), and the resulting weld cross-section are all illustrated with worked examples.
What is the WPS and PQR qualification process per ASME Section IX?
ASME Section IX process: (1) Draft preliminary WPS with essential variables (base metal P-number, filler metal F-number, welding position, PWHT, preheat temperature), (2) Qualify by welding test coupon per Article IV, (3) Perform mechanical tests — tensile (minimum UTS = lesser of base or filler metal), bend (180 degrees, 2T radius for P-1 materials), (4) Record all actual variables in PQR, (5) Certify WPS referencing the PQR. Re-qualification required when essential variable changes (e.g. P-number group change).
What Indian welding standards and certifications are covered?
IS 7307 Part 1:1974 (approval testing of welding procedures for metallic materials in India), IS 7310 Part 1:1974 (approval testing of welders for fusion welding), ASME Section IX as basis for pressure vessel WPS in Indian projects, DGMS approval for mining equipment welding, PESO approval requirements for pressurised vessel welding, and BHEL/ISRO welding procedure requirements as industry case studies.
