Welding of reinforcing steel

sprawnie prętów zbrojeniowych

Reinforcing steel bars are manufactured using several processes and usually have a ribbed profile. Taking this fact into account, it is obvious that from both the welders / welders and the welding supervision a special level of skill and technical knowledge is required and that special procedures should be adopted for quality assurance.

ISO 17660 standard covers the welding reinforcing steel and stainless-steel reinforcing steel for load-bearing joints in the production workshop or on the construction site. The standard specifies the requirements regarding the material, design and execution of welded joints, welding personnel, quality requirements, inspection, and testing. Welded joints of reinforcing bars can be divided into load-bearing weld joints and non-load-bearing welds

According to the EN 1090-2 standard, even for construction class EXC 2 of non-load-bearing joints, welding of reinforcing steel with structural steel should be performed in accordance with the recommendations given in the EN ISO 17660 series. However, for load-bearing joints, a qualified welding technology is absolutely required.
