What is deformed rebar steel?
Deformed reinforcing steel bar is one kind of reinforcing steel bars. Commonly, its surface has ribs which has three kinds of shape: spiral shape, herringbone shape and crescent shape. Deformed reinforcing steel bar with high strength can be directly used in the reinforced concrete structure and also can be used as prestressed reinforcing bar after cold drawing.See all results for this questionWelding of Rebar - Structural engineering general astm a706 weldable rebar Surface treatmentMay 19, 2003 · CWIC (Specifier/Regulator) 14 May 03 12:10 ASTM A706 is considered "weldable" rebar. There are many types of reinforcing steel that are also weldable, but the 706 has a distinct marking of "W" (weldable) stamped into the deformations for identification.

This rebar grade is processed in open hearths, electric furnaces, or basic oxygen furnaces and is available in numerous grades, including grade 60 and grade 80.Can all steel rebar be welded? Not all rebar can be welded , particularly with the exothermic welding process as it must be able to heat the surface of the metal rebar to the melting point in order to ensure adhesion. In general, only steel rebar that is "Grade W" can be welded.See all results for this question
Can You Weld rebar together?
Many people avoid welding rebar because the concrete and the rebar in the final piece will expand and contract at different rates, so having the rebar welded together creates pressure points where the concrete can crack.See all results for this questionCTN-G-2-15 echnical Note - CRSIStructural Welding CodeReinforcing Steel (2011), which describes the procedure for the welding of steel reinforcing bar. This includes determining the weldability of the steel, joint preparation, any required preheating before welding, and temperature control during and after welding.
