Welding of reinforcement


Welding of reinforcement should be avoided wherever possible. Where it is essential it should be carried out in accordance with the requirements of BS EN 287-125, BS EN 288-326 and BS EN 1011-227 and Appendices 6 and 10 to the CARES Steel for the Reinforcement of Concrete Scheme28. Welding procedures and welder qualifications should be subject to the agreement of the Contract Administrator. BS 712329 does not adequately cover the requirements for welding and welding procedures in relation to reinforcement.

Semi-structural welding

Semi-structural welding of reinforcement should only be carried out by firms that have achieved certification to CARES Appendix 10 – Quality and operations assessment schedule for the manufacture of preassembled welded fabrications using welded semistructural
and/or structural joints28.

Tack welding

Tack welding on site should not be permitted, other than in particular circumstances for which special approval must be sought. Only firms that have achieved certification to CARES Appendix 6 – Quality schedule for the tack welding of reinforcing steel28, should be permitted to undertake contracts to supply pre-assembled tack welded fabrications. Where tack welding is proposed for reinforcement with a Carbon Equivalent greater than 0.42, the appropriate procedures in BS EN 101127 must be followed.
