Manufacturing
Guaranteed quality
Comprehensive welding experience and quality assurance is key in custom projects. We monitor and develop the quality of welding according to the welding-specific ISO 3834-2:2005 certificate. In order to ensure quality and improve cost efficiency we utilise automatic and semi-automatic welding methods as often as possible. In addition, all of our manufacturing employees are certified professionals in welding, who possess the required process skills. We have a total of 280 welding method certifications, which authorise us to process even the most demanding materials, like titanium.
Third-party audits
We can also take care of statutory demands and fulfilling quality standards on behalf of our customer. We utilise certified third-party auditors in addition to our own quality control. They will, for example, conduct NDT and DT testing.
