The new Welding Calculator App by voestalpine

Welding is a complex process. Apart from the required welding technology, elaborate designs need a lot of engineering sensitivity, a deep understanding of different materials as well as an enormous amount of calculations. Until now, these calculations required a ton of effort and were highly time-consuming.

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 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 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 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.
