WeldExp calculations

IIW Carbon Equivalent

CEV ranges and validity data calculated from the chemical composition of base materials.

HomeIIW Carbon Equivalent

Carbon equivalent combines the effects of several chemical-composition elements into a single calculated characteristic. Based on the available composition data, the WeldExp database also records calculated CEV ranges and their validity conditions.
