Ewf has created an integrated manufacturers certification scheme, which complies with iso 3834 on welding quality requirements, which is in place since 1998, iso 14001 and oshas 18001 on environment and also health and safety, which are in place since 2000. The scheme has been adopted by iiw, only for the quality field.
Special considerations for low stress concentration welded joints are also given. In order to demonstrate the use of the guideline, the book provides several fatigue.
Ewf has also considered the function of welding inspection and has published guidelines for the education of welding inspection personnel at four levels. It is highly probable that these will form the basis of the iiw scheme when it is finalised. They may yet be totally accepted as they exist in a manner similar to that for the welding engineer.
