One of the basic activities in all quality control processes in various industrial and construction industries is inspection by destructive or non-destructive methods. They show their key role in controlling the quality of welded equipment. In order to ensure the proper performance and health of welded joints in operating conditions, various codes and standards often refer to weld inspection and the acceptance range of defects in various NDT inspectors. This assurance is achieved when the inspection is carried out by a trained and qualified inspector in 3 stages before, during and after welding.

Iran Quality and Standard Inspection Company since 1996 using a strong team of experienced and certified welding inspectors and using specialized measuring equipment with the aim of creating quality management systems in manufacturing and service companies and ultimately improving the quality of industrial products to As the executive arm of quality policies of the Ministry of Industries and Mines, it has provided valuable services to the industry of the country and this social mission is still ongoing.

Due to the wide range of duties of the welding inspector and also in order to ensure the use of maximum quality, specialized inspectors related to that field have been used in various projects.
