Welding of reinforcing steel - Tack weldability - Test methods and performance requirements

This Technical Report presents a method to verify the  tack weldability of reinforcing steel. The purpose is to ensure that sufficient strength and ductility will remain in the welded material when short welding times are applied. This Technical Report does not cover the welded joint itself.

Soudage des aciers pour armature - Soudabilité au pointage - Méthodes d'essai et exigences de performances

Le présent Rapport technique présente une méthode permettant de vérifier la soudabilité au pointage des aciers pour armature. Le but est de s'assurer que le matériau présente encore une résistance et une ductilité suffisantes après avoir été soudé avec un temps de soudage court. Le présent Rapport technique ne couvre pas le joint soudé proprement dit.

1 Scope

This Technical Report presents a method to verify the tack weldability of reinforcing steel. The purpose is to

ensure that sufficient strength and ductility will remain in the welded material when short welding times are

applied. This Technical Report does not cover the welded joint itself.
2 Normative references

The following referenced documents are indispensable for the application of this document. For dated

references, only the edition cited applies. For undated references, the latest edition of the referenced

document (including any amendments) applies.

EN ISO 4063, Welding and allied processes - Nomenclature of processes and reference numbers (ISO

4063:1998)

EN ISO 15630-1, Steel for the reinforcement and prestressing of concrete — Test methods — Part 1:

Reinforcing bars, wire rod and wire (ISO 15630-1:2002)
3 Chemical composition

The restrictions to the chemical composition should be in accordance with the relevant standard for the

weldable reinforcing steel concerned.
4 Welding processes

The tack weldability test is carried out by welding process 135 (see EN ISO 4063). Tack weldability is also

considered verified for the welding processes 111, 114, 136, 21 and 23 down to 0 °C.

5 Test piece

The test piece is made by welding a straight row of tacks in accordance with Table 1 and Figure 1 on straight

pieces of the reinforcing steel bar with a length suitable for tensile and bending t
