The Carbon Equivalent (CE) Calculator is an essential tool for engineers, metallurgists, and welders to assess the weldability of steel. By quantifying the combined effect of alloying elements, it helps predict susceptibility to hydrogen-induced cold cracking and determine necessary preheating temperatures for safe and efficient welding procedures.
Formula:
The most commonly used formula for Carbon Equivalent Value (CEV), also known as the IIW (International Institute of Welding) formula, is:
CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15
Where the variables represent the weight percentage of the respective alloying elements in the steel:
- C: Carbon
- Mn: Manganese
- Cr: Chromium
- Mo: Molybdenum
- V: Vanadium
- Ni: Nickel
- Cu: Copper
