Covers the requirements for welding reinforcing steel in most reinforced concrete applications. It contains a body of rules for the regulation of welding reinforcing steel and provides suitable acceptance criteria for such welds. Coverage includes: reinforcing steel base metal; standard units of measurement; base metal stresses; allowable stresses in welds; effective weld areas, lengths, throats and sizes; transition in bar size; indirect butt joints; interconnection of precast members; preparation of base metal; filler metal requirements; minimum preheat and interpass temperature requirements; welding of coated base metal. Also gives tables and diagrams.
