Manuelle Schweißverfahrensqualifizierung blockiert Produktionsdurchsatz

1 verified sources

Definition

DIN EN ISO 15614 specifies welding procedure qualification requirements. In railroad equipment manufacturing, each weld joint group (different materials, thicknesses, positions) requires a Procedure Qualification Record (PQR) backed by mechanical test results (tensile, bend, hardness). Current process: manual test scheduling → lab testing (3–5 days) → report transcription into WPS document → engineering review (2–3 days) → customer approval (5–10 days) = 10–21 day cycle per procedure. With 5–10 active product variants, concurrent PQR backlogs = production freeze. EU Machinery Regulation and DIN require auditable documentation, further increasing review overhead.

Key Findings

  • Financial Impact: €60,000–€250,000 annual revenue loss (delayed shipments, customer penalties per late delivery: 0.5–1% of contract value); 200–400 hours/year labor in PQR administrative tasks; 2–4% capacity utilization loss during procedure approval bottlenecks; 3–8 customer complaints/year due to schedule slips.
  • Frequency: Per new product introduction (1–2 times/year); Per weld material substitution (2–4 times/year); Triggered on customer specification change or supplier change.
  • Root Cause: WPQ test data (tensile strength, bend tests, hardness) collected manually from lab equipment; transcribed into Excel/Word reports; no automated API integration between testing machines and WPS document management system; approval workflow lacks digital workflow (email-based sign-offs, lost PDFs); customer PQR requests trigger re-scanning and re-compilation from archives.
