Question about welding slang term

admin

I see it a lot, and I think I have an idea what you fellers are referring to, but I would love a proper description:Coupons.Coupon shaped chunks of plate?Sorry for the ignorance.-az-
Reply:I've always heard the term used to refer to small pieces of metal used for practicing welding or weld process development.
Reply:Coupon refers to a test piece used in a welder qualification or weld procedure qualification. The term is sometimes used to refer to the test piece itself ("go to the bench and throw a weld coupons"), or to the pieces that will be welded together for the test ("take two pipe coupons and weld them together using TIG root and 7018 fill and cover"), but, according to most of the AWS and ASME documentation I have, the 'proper' use is to refer to the actual samples cut from the weld for testing ("four coupons are cut from the pipe and subjected to side bends")
Reply:enlpck has the correct answer.refers to the small strips or sections of metal that come out of a test weld for things like bend tests or tension pulls. It also can refer to the test plates themselves.For example if you do a plate test under D1.1 usually the plates will have to a be a minimum of 6x10"  when you're done you cut out a few small strips, and those are usually called the test coupons.Welding EngineerCertified Scrap Producer
