If you meant a from 1992 named “WRC” — that’s less likely; 1992 PC software wasn’t called that.
This comprehensive guide explores everything you need to know about the WRC-1992 diagram, the scientific formulas behind it, how to use a calculator for your own alloy compositions, and where to find reliable digital tools.
To understand why the WRC-1992 diagram and its calculator are so respected, it helps to know what they fixed:
Estimate the dilution percentage based on your welding process (e.g., TIG usually has 10–20% dilution; MIG has 20–30%; SAW can have up to 50%).
If you are looking for specific calculators, many welding supply companies offer online tools that apply the WRC-1992 formulas automatically. If you want me to, I can: wrc-1992 diagram calculator
The (officially titled "WRC-1992 Constitution Diagram for Stainless Steel Weld Metals: A Modification of the WRC-1988 Diagram") is a predictive metallurgical tool developed by Damian J. Kotecki and Thomas A. Siewert, and published in the Welding Journal in 1992.
One example: The (World Administrative Radio Conference) led to the “1992 ITU Radio Regulations” — and some companies (like IFR, Rohde & Schwarz, or AEA) produced chart-based frequency/bandwidth calculators for field engineers.
The WRC-1992 diagram is deeply embedded in global welding codes and standards to validate Welding Procedure Specifications (WPS).

Solidifies completely as ferrite. Common in duplex and ferritic stainless steels. Limitations of WRC-1992 Calculators
Very effective for predicting outcomes when joining different types of steel (e.g., 304 to A36).
