I'm welding threaded bungs into 1 inch D.O.M. tube and keep getting pitting and porous welds. what could be contaminating them? I tried to clean everything well. not using a gas lens. and using orange 3/32 electrode.

not yet. have to do some other things first.
Troll?
Better be careful of what you type.:nono:
Notice what it says next to my av.....
On second angle look you are correct and I am not.
But that first pic SURE does look like a hole and crack and trust me.
I see EVERYTHING.
...zap!
Yep...Oh brother....
So a title excludes you from being an a-hole?
And if anyone accused you of being a troll I would get on their azz too.
...zap!
If I was acting like one I would expect to get called out on it.
Your torch must have some mighty long leads to reach the top of that tower you put yourself in.

finally someone with some welding knowledge lol
thats clearly a gas issue, no shielding gas or leak. can you hear the gas at the cup. how much gas are you running.
Try the above first. run a bead on plain mild steel and show results.
and metal doesnt have to be shiny to tig weld you can weld some pretty nasty stuff tig. Just got to know how. I rarely ever clean metals.
like that mild steel above I wouldn't clean it unless it needed to be pretty
Thanks...
And F.W.I.W....
I don't care for the pics my phone take either...
They suck big time compared to ones I take with a real digital camera....

It's best to get in the habit of cleaning your metal. Your weld will be much stronger if the metal is clean. I like my welds to look good!
Here's some more, "welding knowledge" for you. Mill scale takes more amperage to weld through, is a contaminant, and causes undercut and lack of fusion.
"Can" you weld through it, yes. Should you, no.

Ztfab welding school 101 right there!
no clean unless it needs to be pretty. as long as their is penetration and no undercut then its good to go in my book
