existing steel structure that was constructed with ASTM A7 steel. Is welding to A7 steel acceptable? Possibly, and the answer for your case can be determined with guidance given in AISC Design Guide 21, which states: The weldability of A7 must be evaluated on a case-by-case basis. The ASTM A7 specification was in effect for 67 years, and millFile Size: 185KBPage Count: 2Working with Epoxy-Coated RebarSep 10, 2015 · ASTM A615 reinforcing bars can be welded, but may require preheating the bars up to 500° F. After completion of the welding on epoxy-coated bars, the damaged areas shall be repaired using patch materials meeting ASTM A7. As far as removing the coating, there should be enough removed so that there is no epoxy remaining in the path of the weld.When was A7 Steel consolidated into A36 steel?The early 1900s steel was, ASTM A7 for bridges and A9 for buildings. Both consolidated in A7 steel in 1939. In the early 1960 A36 was available. Please let us know here why this post is inappropriate.

What's the difference between ASTM A7 and A9?
The ASTM A7 and A9 standards were consolidated in 1939 into one ASTM A7 standard for bridges and buildings. This remained the primary structural steel standard until the early 1960s when ASTM A36 became the predominant structural steel used for building construction.See all results for this questionWhat was the purpose of ASTM A7 steel?ASTM A7 was the steel used for building and bridges when riveting and bolting were the methods used to fasten members together. Since welding was not a concern, carbon, sulfur and phosphorous were not controlled.Reference: app.aws.org/forum/topic_show.pl?tid=31597See all results for this questionWhat was the name of the withdrawn ASTM standard?A89-43 Withdrawn 1947: Specification for Low-Tensile Strength Steel Plates of Flange Carbon-Qualities and Firebox A91- Withdrawn 1940: Methods of Determining Weight of Casting on Tin, Terne, and Lead-Coated Sheets A93- Withdrawn 1965: Specification for Zinc-Coated Galvanized Iron or Steel Sheets, Boils, and Butt LengthsSee all results for this question
