Welding technology know-how unites

The welding specialists at voestalpine subsidiary Logistik Service GmbH (LogServ) and voestalpine Schienen GmbH have been in active contact for a whole year. Now they're working together on a project.

Welding rails demands significant know-how. The high-quality rails produced by voestalpine Schienen GmbH in particular require the appropriate welding technologies. That’s why the welding experts at the Competence Center Welding (CCW) in Donawitz have been consulting closely with welders at voestalpine Logistik Service GmbH (LogServ) in Linz for around a year, to optimize the use of synergies within the voestalpine Group. This teamwork is already being realized in a project: both companies are involved in the Schienen OÖ GmbH rail track construction site for the local railway to Traun.

Tram line 3 in Linz is being extended as far as Schloss Traun in two construction phases. The construction firms are currently working on the first phase which runs to the Trauner Kreuzung. The track system is being built by GLS which is subcontracting voestalpine Logistik GmbH (LogServ) to undertake the welding work. And as chance will have it, the rails for the track extension are being supplied by voestalpine Schienen GmbH – a perfect reason to continue the excellent teamwork with the welding experts at the Competence Center Welding.

Demanding the highest quality

Extreme precision and the utmost competence are needed as the project involves welding at tolerances of a tenth of a millimeter. Rather than being welded in fixed settings, as is standard, the rails are lying exposed. That’s why Schienen OÖ GmbH specified the highest levels of welding competence, including only certified track welders working on the track. Every single weld seam is examined and approved using welding technology developed by voestalpine Schienen GmbH (Compentence Center Welding).

Leveraging on synergies within the voestalpine Group

A major challenge for LogServ proved to be the last minute change in welding method prior to the project start. Although the original tender had specified so-called aluminothermic welding, shortly before work began this was altered to filler-wire welding, a method reserved for particularly experienced welders. Again, in such cases the ability to draw on competencies from within the voestalpine Group and consult internally is a huge advantage. There are likely to be many more joint projects for the welding experts at LogServ and voestalpine Schienen GmbH in future.
