Tig welding practice tjoint.

[Deleted member 371759]

Some TIG welding practice. Feel free to tell me how terrible I am. 3/32 2% lanthanated tungsten, 160 amps. 11/64th hot rolled steel . 15cfh argon. Stubby #8 gas lens.

A little ruff at the beginning, very good in the middle (steady and constant) but then there is some porosity at the end... I am sure you know what you did wrong at the beginning but do you know what went wrong at the end ?

You are doing good, keep it up and do more of what you did in the middle.

I may have taken the filler out of the argon shielding.

Might be a touch cold, but hard to tell from that photo. The HAZ is quite often your best indicator of how well it went. That nice blued line on the vertical leg shows that you started off a bit cold (perhaps did not wait long enough to build the puddle), then ran pretty consistent until you ran into some problems in the last ~inch and then started to put in too much heat as you probably stalled out a bit. Generally I'd say that is quite decent esp if you are saying this is like a first attempt. Far better than I ever started off...

I was looking at the last part also, with their big rounded appearances. Those do look a little cold.
It has been a while since I did any tig welding, and I am sure that is probably a lot better than I could do!

I always say to myself, It's good enough for who it's for. Or I'm not building a spaceship.

That would get the job done around here.

Some of todays practice.

Practice is the key. Also remember to run a bead before you start to weld on repair just to get the feel going again. Otherwise your doing great and it will get better!

With both of those joints I find I need to hold the arc on the bottom plate much more and wash up to the T or the lap piece. The bottom piece tends to soak up more heat as it is in the middle of the coupon whereas the other piece is just hitting an edge. That is why you look a bit cold on the toes at the bottom plate. Very nice consistency. I wish I could be so consistent!

Tonights joint. Then I blew the corner off a piece of 1/8th inch because I got stuck got angry and quit.

Next step is to bandsaw a cross section perpendicular through the bead and look at penetration. BTW, are you left handed?

Here is some coped pipe from today. Think she got a little warm.

If I was you I would just get rid of that TIG machine. Send it to me. I could always use another. Take up needlepoint instead. Even better, keep TIG welding because your weld looks fine and your welds will only get better. I know, you will get a lot of nit-picking advice, which is fine, but your weld bead really looks better than many of the beads I see done by folks who weld for a living. There is a little difference in travel speed and it looks like the shielding gas may have been blown away in one spot, but that could just be the camera. I'm pretty sure you know already where the weld bead is not ideal and don't need anybody here to tell you. But to reiterate you bead is pretty good and if you did that bead for me and I was paying for the work I wouldn't complain.

Thanks. I really appreciate that. Im trying hard to get good at tig welding. I does not come naturally to me. Im not a super coordinated guy. So its going to be interesting. Im also not super artistic which it seems like a lot of good tig welders are.

Trying out a technique I saw Jody from welding tips and tricks do. He called it back step. Start in the middle and took it to the tapered end then start at the end and take it to the middle. Kinda a cool technique to keep the heat out. Terrible weld but you get the idea.
