  • Int’l Welding Approval Stamp

ISO 3834 in conjunction with ISO 14371 has since become mandatory for welding products sold on the International construction market. Under the regulation, all companies that manufacture or supply structural steel for the International market are required to have a documented welding quality management system in place, and will need to either employ or have access to a Responsible Welding Coordinator (RWC).

The role of the RWC is to control and supervise all welding activities, and ensure the steel structures meet the adequate levels of mechanical resistance, stability, serviceability and durability.

Depending on the quality requirement category, some specific requirements on the application of quality systems are identified by the standards. One of these requirements is the minimum qualification grade of the welding coordinator.

International Standard organization sets out four Quality requirements category for steel structures and they are based on the intended use of the structure and how critical it would be if it failed. The higher the category, the more stringent the quality criteria. Companies that undertake part 2, 3 and 4 welding activities as stated below, require a Responsible Welding Coordinators (RWC).
