Welding is called a 'special process' by ISO 9001. This is mainly because the quality of a weld cannot be solely verified by a post-weld inspection. Therefore, the entire welding process must be subject to controls. So in order to get a quality weld, not only the final weld has to be tested, but all the important intermediate steps such as design, purchase of material, traceability, presence of the necessary welding documents, production tests, etc. have to be monitored.
Apragaz can also certify your quality management system according to the ISO 3834 standard for the three different quality levels: extended quality, standard quality and elementary quality. (see certification).
