The challenge:
ISW GmbH Steel Components, a company based in Ennsdorf in lower Austria, specialises in the manufacture of large, heavy and complex basic frames for machines and systems. This involves welding black steel with a thickness of 300 millimetres and over, lengths of up to 20 metres and a total weight of up to 100 tonnes. This is completed primarily using a MAG welding procedure and multi-pass welding. ISW welders tried out machines from three notable manufacturers during a test period.
The solution:
After the test period, the ISW welders opted for the EWM machines. The M9 contact tips from EWM have a 15% longer contacting surface in comparison to M8 contact tips and a 30% larger threaded cross section. Contact with the welding wire is better and heat is dissipated more effectively. Thanks to the integrated control and graphic display on the RD3X function torch, all the relevant parameters can be set directly on the welding torch. The LED lighting illuminates dark working areas. The innovative forceArc puls welding process from EWM stands out due to its great penetration even with significantly reduced heat input. The ewm Xnet 2.0 quality management software for welding records welding data in real time and can analyse and manage all welding processes within a network-supported system.
The success:
The result? Increased throughput time and reduced downtimes thanks to a longer service life of the contact tips. The welding torches can last for up to eight hours, as long as it takes on average to fully weld a component in an automated system. Before, the contact tip could only last a maximum of one hour. The integrated control and graphic display on the RD3X professional welding torch saves walking to and fro, as all the relevant parameters can be set directly on the welding torch. The innovative forceArc puls welding process from EWM is the only welding process used in ISW’s production. Less heat input via this process means less distortion and less tension in the component and thus less arduous straightening work. Thanks to ewm Xnet 2.0, quality can be completely and thoroughly proven.
