Welding Inspection Services
Welding process is the most important technical Special Process and permanent joining technology. This process is closely connected with NDT. Therefore, a lot of inspection activities of ATG Group are joined with welding inspection.
The coordination process of welding is described in e.g. ISO 14731 (previous EN 719), where the importance of the inspection of all phases of welding process is clearly explained. As it is defined, the whole welding process shall be planned and realized under control of coordination welding personnel as is e.g. International Welding Engineer or International Welding Technologist.
Nevertheless, all steps of welding process shall be inspected and verified against the governing documents, i.e. contract, or agreed production standards and codes, which are defined in the contract. Such inspection increases the probability of appropriate realization of agreed products. Somebody must be responsible for relatively independent assessment of conformity of all phases of welding process. This person is e.g. the International Welding Inspector.
