Welding Tips and Tricks

I better go practice some more...

As if you weren't going to practice more. No welder on here doesn't need more practice nor do they not practice.

Thanks guys. I don't have any settings really it's just a transformer syncrowave 250. Just 7-10 on the balance. I hate having a long stick out on aluminum, don't know why. It just takes hood time and learning to read the puddle. Anyways thanks for looking!

I noticed in one of your pics an aluminum flange for an NPT plug. Is there a brand of flange or bung that you prefer? I am looking to source some to have in stock for adding drains to pontoons.

I'm not sure it's whatever my work has on hand.

I haven't posted a weld in a while, and this topic is getting buried, so here goes.

It's a socket weld (rare for me these days) done in the position you see it with all the crap in the way. 309 rod, as it's 3/4" stainless pipe to a mild steel valve.

Nice socket weld! You used the gap-o-let right? That weldment doesn't look like it needs any mistakes. I wish I could do your job I had to weld a goddamned sink in a bar today...I hated it

Did you get some good payment or sneak a little while you were there though. If so then probably worth it in the end. I mean you could be 20 ft down in the mud and 3 feet of water figuring out where the hell that tape measure went.

Gap-o-let? I just cut the threads off the pipe section you see (Originally a threaded nipple. I was expecting Rego valves, with FNPT both ends). I then loosely fit these ITT valves (this has a mate exactly opposite) for the standard 1/16" minimum pull-back for a socket weld, used my electrician's level to set the valves at 30*, and a quick tack on top. Squared them up with my TLAR (That Looks About Right), and welded them out.

If it looks straight and level then nobody is going to check and see if it actually is.

Be my guest! I also estimate time on task by the WAG method, which is "Wild-Ass Guess". I always look like a hero, because I use Thomas Edison's rule... However long I think it will take, I double it, then add ten percent, and that's what I tell them.

Under-promise and over-deliver, and they'll beat down your door.

I use the Edison method as well! I just didn't know that's what it was called.

It's been a while since I posted anything substantial.

First time on 304 SS 1 1/2", 1" and 1/2" sch 40. Two passes. Argon purge at 10cfh. 3/32 2%Thoriated with #7 cup (wishing it was an 8).

Getting the hang of these exhaust flex sections! 3" 304, backpurge at 7cfh, welded at 90a w/ 1/16"308L. Pictures arranged chronologically from out of the bag to welded, for those of you who have never had the unfortunate pleasure of welding one!

Great job Sam! I know you like bells and whistles...did you pulse these? You got great color.

No, these guys are anti pulse lol. I welded 1/2-5/8" at a time, mainly because that outer shell is 0.020-0.030" thick in some places. Monster 16 nozzle at 40-45cfh. I don't remember if I included that bit.
