Welding calculators

The Schaeffler diagram provides information on the welding properties of the various types of microstructure, as a function of what alloying elements they contain. This Online calculator provides the Schaeffler diagram for different base materials and a filler metal. After entering the range of the standard analysis and the actual analysis the Ni-equivalent and the Cr-equivalent are calculated and shown in a diagram. The sample data can be overridden and the red backgrounded fields show the results.

Five carbon equivalents from one steel analysis: CET, CE (IIW), Pcm, CEM

and CEN — each shown with its own range of validity. Free, in five languages.

Minimum preheat temperature to EN 1011-2 Annex C.3. Enter the alloy analysis or CET directly, with plate thickness, hydrogen content and heat input.

Calculate the t8/5 cooling time to EN 1011-2 from welding parameters, arc energy or heat input. Shows the transition thickness. Free, no registration.

Calculate arc energy and heat input to EN 1011-2. Start from a target t8/5 cooling time or from voltage, current and travel speed. Free, no registration.

Calculate welding cost from the weld cross-section: filler metal, shielding gas, electricity, time, machine rate and labour including overheads.

Calculate the cross-section and weight of any weld – the MIGAL.CO tool gives the cross-sectional area and weight per metre for all common weld types, with a to-scale sketch.
