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
