Trying for my first weld cert and picked D1.1 1G on 1 inch plate. I'm looking for any tips that y'all could throw at me. -Nick
Reply:Keep it clean, keep your welds flat, no wagon tracks. I generally put the hot pass right on top of the root pass, then I have room to move. On tests I run all stringers. Take a small chisel, hammer, awl, chipping hammer, and wire brush with you.

Reply:Thanks! I should mention that my high school is paying for the test and providing the machine and tools so I'll have tools on hand. -Nick
Reply:I never chance it. I take all the above mentioned tools, but forgot to add, flashlight, and extra clear lenses.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:Never thought of the flashlight, can see where it would be really useful though.
Reply:I'm sure I have, but can't remember ever taking a 1-G test. Here for our state structural test it is just 3, and 4-G. Never was allowed to use a grinder. Wire wheel on a grinder yes. Chip all the slag off with the chipping hammer. Run the chisel, and awl down the toes of each pass, then wire wheel again. The flashlight really helps to look everything over real good before making the next pass.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:We're allowed to use a grinder on this test for some reason but i'm not going to complain about it.
Reply:Test booths tend to have poor lighting so the flashlight is a must have. I the test with a backer bar or open root?
Reply:Backer bar.

Reply:Anything that will make this easier is fair to me (although I know this is a very easy position).
Reply:CEP and TSS all the D1.1 tests i have ever done allow a grinder but the D1.5 tests I have done are no power tools.
Reply:I've heard both ways on both tests so I'm guessing it depends on the supervisor.
Reply:I'll tell you this TSS. Make sure you have good tacks on the backer bar so they don't crack. Allow the plate to cool a bit between passes. I do not mean quench the plate but let it cool. Running to much fill will cause the plate to warp and can show in the root pass.
Reply:Thanks!
Reply:No problem bud.
