stainless exhaust work

admin

hey guys, noobie tigger here, been thru 4 60cu.ft. bottles of argon so far, this is the first thing i've welded that will actually be used for somthing..lolpictured is a 2.5" 304 stainless flange (3/8" thick), welded to some 2.5" .065 wall stainless tubing.2% thoriated 3/32 tungsten308l 1/16" filler~70-75 amps, footpedal controlled ( i couldnt get it to "bite" into the flange very well with less amps)still on the sloppy side of things, but definetly seeing progress, and thats all i can ask for!comments and suggestions are welcome and needed!

Reply:Hey presure2,Well, going thru (4) bottles of gas for practice, at least shows you're doing some homework to learn the techniques for good TIG welds. Your pics show a "decent" weld bead, although it is evident you need to get better control of movements & filler control. Consistency with each will yield those illustrious "dime" beads that all tiggers yearn for. It takes time & much practice..... the more you do, the better you will get. Simply ask yourself: "How bad do I WANT it?" Then answer. You will know.DennyComplete Welding/Machine/Fab.

Reply:I say if it holds up for it's intended life cycle, mission 99% accomplished. Although the other 1% can make you much more proud of your work.I make a habit of looking at all the welding I run across in my daily life, and it's amazing how bad some welding is... only to have it hold up for well beyond it's intended life cycle.Stack of dimes are fantastic, but if I'm trying to make a turbo manifold, I want reliable POWER. Not pretty welds. (I would, however, prefer to have BOTH! )

Reply:Get a nice 2" thick chunk of aluminum and drill and tap holes in to for bolting down the flanges while welding. I always bolt down flanges while welding no matter how small.
Reply:Some of your text got cut off, but I get the idea from the pic, thanks for the tip!
