Thanks guys, I will definitely buy some bar and make my own.

Can I make my own coupons? I have access to a mill and a line burner, or is it just better to buy them. I live in Utah near Salt Lake City but not sure where to buy them. Looking to do 3g structural with 7018, also mig tests and tig. Thanks for any advice.

Just wanting to say hello. I've been welding for almost fifteen years now and look forward to receiving and hopefully giving advice.
