RE: ASTM A615 steel

Weldability depends upon specific composition. AWS D1.4 has you check certs for Carbon and Manganese and determine carbon equivalency. This affects preheat and interpass temperature requirements, for a given diameter. If not  known, D1.4 provides a default value for preheat (300 F for bars #6 and smaller, 500F for bars #7 and larger).
