Effect of welding heat on hot rolled steel

  1. Apr 29, 2010 #1
    Hey guys this might be a question better suited for the Materials Engineering section but I'm not sure how much they deal with welding. Anyway I am trying to figure out how much the heat from a typical welding process would effect a steel's yield strength. I understand that on a cold worked steel the heat will significantly lower the yield strength, but what about on a hot rolled steel? I know there is no specific number but just curious if anyone has any experience with this type of thing and could give me a rough estimate. Thank you.
