voestalpine Böhler Welding

The Welding Calculator App

The Welding Calculator App supports the planning and optimization of welding tasks such as the calculation of cooling time, preheating temperature or the calculation of the required filler metal quantities. As a joint development between the voestalpine Steel Division and voestalpine Böhler Welding, the app is currently available for Android in the Google Play Store and for iOS in the App Store.

An optimum weld seam 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 there is a need for optimization to produce the required welding 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.
