If its not A-706 it may be welded based on the C.E., there will also be preheat requirements. As far as the strength of the electrode use E-70 for a flare-bevel. E-90 is only required for direct butt joints. Besides if you use E-90 it is posible you could exceed the allowable shear stress of the A-36 material. As far as the welder goes, there are no prequalified welds for rebar. I therefore require the weld to be qualified by test and that the welder performing the weld be the welder who does the test specimen. Hope this helps! Mark Harper P.E.
