Structural steel welding Part 3: Welding of reinforcing steel
|Publication Date:||25 November 2014|
This Standard specifies requirements for the welding of reinforcing steel used in concrete structures that are designed and constructed in accordance with AS 3600 or NZS 3101.1, as well as other Standards that may be appropriate, by the following processes:
(a) Manual metal-arc welding (MMAW).
(b) Gas metal-arc welding (GMAW).
(c) Flux-cored arc welding (FCAW).
(d) Flash butt welding.
(e) Flame-pressure welding.
(f) Other processes approved by the principal.
Provision for the MMAW, GMAW and FCAW processes is contained within the body of the Standard. Additional and specific requirements applicable to flash butt welding and flame pressure welding are set out in Appendix B and Appendix C respectively.
The Standard applies specifically to the welding of reinforcing steels complying with AS/NZS 4671, but other steels may be used as provided for in Clause 2.1. It also applies to the welding of steel connection devices, inserts, anchors and anchor details, including prefabricated assemblies required in reinforced and precast concrete constructions.
1 Further information is given in WTIA Technical Note 11.
2 GMAW includes waveform controlled welding such as 'synergic', 'programmable', and 'microprocessor controlled' processes' e.g. pulsed spray transfer, controlled short circuit transfer.
