BTW, im not trying to be a dick, but usually the welding masters answer the questions, not ask them
AWS D1.1 structural test?
2G is a horizontal plate test. The structural test calls for 3/8 plate, 22 1/2 degree bevel, 1/16 (?--it's been a while) land, 1/4 inch gap, 1/4 inch backing bar. The procedure is: Weld it.
Come to think of it, that's a SMAW (stick) test.
Kermdawg's right. Ask a specific question.
(I don't believe I originally replied 2G was vertical... must've been the beer
