Would this pass a 3g slaw test? If not what's wrong with it.... What techniques works best? During a weld test will I be able to adjust the welders amperage or voltage before it begin? Attached Images
Reply:Should the groove be filled? Doing GMAW, that remaining 1/16" is almost perfect for a cap if you can keep the center height within 1/8" of the plate surface (or whatever your SLAW code requires)XMT304 (school)SP125+ (home)HF 4x6 BandsawGood judgement comes from experience and much of that comes from bad judgement.
Reply:I posted this meaning stick welding(smaw) I'm under the impression it has to be to asme code. Any constructive criticism is appreciated. The question still stand would I pass the way it is or do I need to change something
Reply:Visible porosity, lack of fusion, coarse ridges, and underfill - no, this would not pass a Section IX plate test. You need to work on consistency of technique, bead placement (including knowing how thick to make your layers prior to capping), and starts/stops. Per Section IX, you should be welding in accordance with a WPS, and should be permitted to adjust your parameters within those on the WPS accordingly.

Reply:I wouldn't bet on it. Remember, these are going to be subject to either bends or RT.

Reply:No. Your filler pass is too wide, and your bevel isnt filled in. After you get the root in take your time and use stringers. Dont try to fill it up as quick as you can. Use a weave with rod pointed slightly uphill while pausing slightly on the sides to make sure you are tied in. You will absolutly be allowed to adjust your amperage. Every welder is different, and every weldor is different. Lay down some beads before you get started. When your happy with a flat bead turn it down just a tad and practice a verticle. Good luck bud and let the sparks fly.Shake and Bake
Reply:I appreciate all the good feed back. It's good to know I still suck lol. Tomorrow I am gonna bevel out 5/8 plate and hope to get more feedback. I'm very serious about getting more involved in this trade. I'm so damn sick of sitting at a desk talking dumb *** people trying to convince them to buy crap they don't mean. At least with welding you actually see the small difference in the world everytime ya lift your hood. Tomorrow is er70s2 wire with 7018 fill cap. I hope to see some feedback. Thanks guys
Reply:Looks like an arc strike under the restart, not porosity to me. I like to see the sides of the weld fused more but I also don't usually run weave beads. You need to work on filling the joint up evenly, the bottom left side looks like its filled flush/little over the bevel. Keeping the cap under 1/8" with it filled that high can be a little tricky. Good luck with the 5/8" plate, I assume that 70s2 is for a tig root? Be carefull with the first fill pass with 7018 if you only have the tig root and no hot pass it can be easy to burn through.Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG
Reply:Only way to know is to finish the weld and have it tested. Alot of tests if the cap is over 1/8" then it doesn't pass, and with the bottom left filled as high as it is it would be hard to keep it under 1/8".Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG |
