 The only way to achieve an optimum weld seam is to perform precise calculations in advance. Such calculations must take a large number of formulas and parameters into account.

The voestalpine Welding Calculator simplifies your everyday work in this respect.

Welding Calculator

Life can be so simple

The voestalpine Welding Calculator provides you with support in the planning and optimization of welding tasks such as the calculation of the cooling times and preheating temperatures or the required quantities of welding consumables.

Download the voestalpine Welding Calculator app to your smartphone or use the online version on your desktop.


An optimum weld seam is just a click away with the following modules:

Cooling rate t8/5 pursuant to EN 1011-2

Checks whether the selected welding parameters are within the recommended processing range or whether optimization is required to produce the desired weld seams. The integrated retroactive calculation makes it possible to adapt welding tasks as required.

Preheating temperature Tp

Calculates whether unalloyed and low-alloyed steels (pursuant to EN 1011-2, Annex C.3, CET design, and pursuant to ANSI/AWS D1.1, Annex H, Pcm design) must be brought to temperature before welding in order to avoid cold cracking. The need for edge drying is examined based on the climatic conditions.

Filler material quantity calculations:

Just the right quantity of filler metals per weld seam.
