: It calculates the Chromium Equivalent ( Creqcap C r sub e q end-sub ) and Nickel Equivalent ( Nieqcap N i sub e q end-sub ) using specific formulas:

Solidifies as primary ferrite, transforming to austenite during cooling. This is the ideal zone for most austenitic welds to prevent cracking.

) was added to improve prediction accuracy for modern alloys. 1. Chromium Equivalent ( Creqcap C r sub e q end-sub wrc-1992 diagram calculator

By plotting the points on the WRC-1992 diagram, the point representing the weld metal (C) falls between the FN=40 and FN=46 iso-ferrite lines. This allows a skilled interpreter to predict the FN of the weld metal to be approximately 42.7 .

To use the WRC-1992 diagram calculator, follow these steps: : It calculates the Chromium Equivalent ( Creqcap

formula excludes Manganese because its effect on ferrite formation is non-linear and varies based on the overall composition. Inclusion of Copper (

Q: Is the WRC-1992 diagram calculator applicable to all materials and welding processes? A: No, the calculator is limited to carbon and low-alloy steel weldments, and may not be applicable to other materials or welding processes. To use the WRC-1992 diagram calculator, follow these

Unlike its predecessors, the WRC-1992 diagram minimizes prediction errors for modern stainless steels, particularly duplex and highly alloyed grades. The Mathematical Formula Behind the Calculator

Expanded the WRC-1988 database; added a dedicated term for Copper ( Accuracy drops outside its specified boundaries ( Creqcap C r sub e q end-sub 4. Evaluate Solidification Modalities
