Hello,I am having a tee joint on 1/4 inch mild steel plate welded and I would like to know would 3 passes at 130 amps, 1/16 tungsten, 3/32 A18 filler, small v prep with 1/32 inch gap be acceptable for a wishbone pickup bracket on a track car.  The joint will only be welded on on side of the filler but a U shape will be made just with a base that is wider than the gap.A certified welder is doing it and that is the highest output tig available.  Although it must be tig welded. No mig or stick allowed.ThanksLast edited by v12 guy; 07-08-2013 at 02:56 PM.Reason: Filler size
Reply:Maybe 130 amps and 100% helium.  130 amps is good for 1/8". Or preheat the crap out of it.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:130 amps 3/32" tungsten would prob be better. With three passes at that amperage the weld will still prob be a little small for 1/4" fillet. 3/32 or 1/16"filler would also do better, with 1/8" its hard to feed extra wire into the puddle at that low amperage.Airco Ac/Dc 300 HeliwelderMillerMatic 200 (stolen)Miller Maxstar 150STLMiller AEAD200LE (welding and generating power) Hobart MIG
Reply:I have seen the test piece he did and the metal broke before the welds.  The rear piece is 20 inches long and took 20ft of 1/8 filler.  He just complete the first piece so I want to get some opinions before teh second gets worked on.  Sorry no pics cause the camera is broken.
Reply:Woops the filler is 3/32 not 1/8
