scope:

This document is applicable to the welding of weldable reinforcing steel and stainless reinforcing steel of load-bearing joints or non-load-bearing joints, in workshops or on site. It specifies requirements for materials, design and execution of welded joints, welding personnel, quality requirements, mechanical testing. All provisions except subclause 9.2.3 apply t o load-bearing joints. The requirements for non-load-bearing joints are specified or illustrated in the subclause 6.1, 6.3, 6.5, Clause 8, subclause 9.2.3 and 13.

This document also covers welded joints between reinforcing steel bars and other steel components, such as connection devices and insertion anchors, including prefabricated assemblies.

This document 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 this document are only applicable to static loaded structures. For fatigue-loaded structures, depending on type of joint and welding process, it is recommended that an appropriate reduction be taken into account on the fatigue strength of the reinforcing steel.
