ISO 3834 level 2-certified (the highest norm), Graux guarantees welds of the highest quality.
In addition to their concrete experience, every welder is certified under the ISO 9606-1 :2012 norm on a variety of welding operating modes. Whatever the type, the position, the metal, the thicknesses, the filler metal, you will always find a qualified specialist at Graux.
Upon request, our international welding specialist (IWS) creates a specific welding notebook for your project containing the welding plans, complete traceability of the filler metals, the qualifications of the welding operating modes (WPQ), the demonstrations of the welding operating modes (WPS) and the non-destructive or destructive controls (PT; MT; UT).
In order to control the integrality of our welds during and at the end of the manufacturing process, the Project Managers are also welding coordinators.
