Reinforcing steel bars are produced by a number of process routes and usually have a ribbed profile. Taking these issues into account, it is apparent that both the welder and the welding coordinator require a specific level of skill and job knowledge and that special procedures for quality assurance need to be adopted.
BS EN ISO 17660-1 is applicable to the welding of weldable reinforcing steel and stainless reinforcing steel of load-bearing joints, in workshops or on site. It specifies requirements for materials, design and execution of welded joints, welding personnel, quality requirements, examination and testing.
BS EN ISO 17660-1also covers welded joints between reinforcing steel bars and other steel components, such as connection devices and insert anchors, including prefabricated assemblies. Non load-bearing joints are covered by BS EN ISO 17660-2.
BS EN ISO 17660-1 is not applicable to factory production of welding fabric and lattice girders using multiple spot welding machines or multiple projection welding machines.
The requirements of BS EN ISO 17660-1 are only applicable to static loaded structures.
