CSA W186-M1990 (R2016)

Preface:

This is the third edition of CSA Standard W186, Welding of Reinforcing Bars in Reinforced Concrete Construction. It is written in SI (metric) units and replaces the previous editions published in 1981 and in 1970.

Scope:

1.1
This Standard applies to
a) the design, fabrication, and inspection of welded connections utilizing deformed reinforcing bars and to the certification of companies involved in such work;
b) welding of deformed reinforcing bars (except for pre- stressing steel or for bar or rod mats for which the welding is covered by the manufacturing specification) either directly to each other or through splice members; and
c) welding of deformed reinforcing bars to structural steel members used as anchorages in precast or cast-in-place concrete construction either in the fabricating shop or in the field.

1.2
This Standard does not cover welding of plates, angles, or other structural members to one another. This is covered by CSA Standard W59, Welded Steel Construction (Metal Arc Welding).
