By predicting the FN, you can ensure your weld stays within the "safe zone"—typically 3–10 FN for austenitic steels to avoid solidification cracking How the Calculator Works: The Math Behind the Lines
Select the appropriate curve based on frequency, antenna height, and percentage of time (e.g., Curve 1 for 50% time, 100 m HAAT).
: It allows users to input the compositions of the base metal and filler metal, then applies a dilution percentage (often 30%) to predict the final weld metal chemistry.
