Journal restoration or impeller tip repairs under standard guidelines often rely on the welder's general experience. API 687 requires strict Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) tailored to the exact chemistry of high-strength turbomachinery steels (like 4140, 4340, or 17-4 PH stainless). It mandates precise Pre-Heat and Post-Weld Heat Treatment (PWHT) cycles to avoid creating brittle heat-affected zones (HAZ) that fail under operational stress.
