Here are some work pics.

Any videos you can link me to that could help teach me to learn this type of weld as I cannot seem to get the same effect,

Kyle, get the new torch on?

Yes! It worjs great except i jabent switched regulator and was getting argon contamination, got some apit back inside the cup that i had to clean with a wire brush. How much cfh do you use? I was using 12

 

[Gamble97]

15-20 normally, for the large one 25-30

 

[Archer Fabrications]

Okay i was using the large one at 12 i had a great bead at first then it started spitting after that. 30is a lot

 

[compression]

Damn I use nearly 40 sometimes, ecspecially if I feel any slight breeze.

Im going to build a purge box.

If you use too much you can get a suction effect for oxygen similar to how a sand blast gun works. And it will contaminate your argon.

The cup I use is like wide the #### open and I generally use nearly an inch of stickout.

Like this? 40 still way too much.

Not quite it doesnt have a .... barrel? I guess. Its like 3/4" in total length.

I use the same Pyrex cups and gas lens.

Honestly I don't pay a lot attention to the flow on purge. I let it go until it feels "good" 30 Sometimes higher 45.


But coming out of the torch I like it closer to 17-20.
And I like to purge the spot before I weld for at least 1-3 seconds.

Like urban said, if the flow is too high it creates turbulence that actually pulls air into your purge gas.

I saw a demo once where the flow was cranked up out of the torch with a smoke tint stuff added to the gas. Well with the inert gas being pushed out with so much force and velocity the surrounding air actually blew the inert gas all around. As well as the air on the sides of the cup being sucked up into the cup because of high flow.


It was crazy to watch. And hard to explain

 

[Archer Fabrications]

Link for video? I was referring to torch gas only, 40 is too much. I Iike 12-20 15-20 for aluminum. I purge about 1-2psi or like 30cfm what is your pre flow at on the torch?

 

[spoonman]

Standard collets and cups worked great for decades. If the torch is close to the metal the heavy Argon will push the air out if the way. Long style cups where prominent then.

Modern gas lens work the same as suction diffusers on water pumps. The mesh screen makes the argon have a more laminar path that it follows.

Honestly I don't know why they even sell standard collets besides price.


Heat input, oxides, shielding gas. They all intermingle. To slow of welding and base metal and surrounding area will form oxides/impurities.

Not enough shielding gas, same thing.

Oil, rust, dirt on base metal and it will show in your puddle, you will see it burnt out in the bead.




Another rant. All the guys out there welding Titanium parts and dump tubes.... You are doing it wrong. Completely. How all these thin dump tubes and exhausts haven't fallen apart, is beyond me.


How to weld titanium 101.
Purge chamber.
$3000 purge moniter.
Acetone on everything.


Don't have a purge chamber? Huge gas lense cup, $400 trailing shield, and take breaks after each little bead as you must keeping inter pass temps as low as possible.


Titanium dust is extremely flammable, can not be put out with a standard fire extinguisher.


There should be absolutely no color at all. Titanium is extremely easy to contaminate, it reacts very easily with air, and burns with excessive heat.

I just added the purge part.

But I agree with your torch flows.


This was a live demonstration. I have seen a photo or two on google that compares gas lenses to standard collets. It was the same smoke tint in the gas.


And I have my torch set to around 17-20. I have a valve on my torch and I simply get in position and turn on the flow, wait a second or two then start the arc with my pedal, or scratch start if welding pipe.


The .3-.9 second preflow that most machines have is way to short on SS

I was thinking preflow was a little quick but I'll just pedal twice like thd synchrowaves for extra pre, i need to do some beads in my garage bench but it's been 19*f out colllld

 

[spoonman]

I just feel like I get cleaner starts if I let the purge from the torch do it's thing before the arc lights.





My dad is a industrial Boilermaker and he was on a job welding 6" sch 80 ERTi-5. He sent me a picture of a 50lbs container of filler rod. Price $7000.

I can't even imagine the price of the pipe that was being installed. $100,000 up to millions. No idea.

It carried high pressure liquid hydrogen.


So yeah, when I see guys palling around with Ti it baffles me.

First beads in 2 months.

Still shakey on hand from being rusty.

20cfh on torch, 70 amps 1/8 ss

Gambles torch and pyrex cup are awesome

 

[antilag_200]

damn you guys and your colored stainless welds. Looks good urban

 

[Archer Fabrications]

I LOVE the torch setup seriously, best money ive spent in a while!

Here's some flux dual shield I've been doing at work, aluminum wire and some stick

.040 tungsten and 12amps. Weave.

.040? Is that 1/16? Looks like crap gamble, razor blades are easier than 1" plate steel! just messin looks good.

Now lets see the back side

 

[crash89]

God damnit it need a TIG welder!!!!

 

[turtlebain]

Just picked this up to make small brackets & things, just practice in general.

Nope it's .040 which is 1 size smaller than 1/16.
Here is the back.
