Because who likes tig welding in a hole suspended by a crane.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

Running a compressed gas cylinder or even a hose down in a hole requires even closer monitoring of air quality. I'm not sure what kind of shaft he's going to be in but unless it's a pipe open on both ends with good ventilation I'd be cautious. But even the ss stick has requirements for ventilation because of (hexavelantchromium) not sure of the spelling.
I have more questions than answers

I would love to TIG in a hole suspended by a crane, sounds like serious fun.
Hexavalent chrome is dangerous in any case, TIG, MIG or stick.
You could get the PAPR ( i think is how its spelled) with the new Panoramaxx helmet and THEN you'll be good to go
Or the Miller version or 3 M or whatever, maybe that's not enough or maybe you hook a hose to the intake of the fan shooting your air in there and just make sure your buddy up there is not a prankster.

Well, considering argon is heavier than air, and the amount he is using, I would assume it would be allright.Poland308 wrote:Running a compressed gas cylinder or even a hose down in a hole requires even closer monitoring of air quality.

Long hoses man, that's all I gotta say, could be done. But whatever is best for him, I would just take it all the way

Here's a pic of the 120ft shaft.
Haven't touched a TIG torch in over a year but I'm good to go with SS FCAW with Tri-Mix. I'm not too concerned about ventilation but will keep that in mind when I pull the trigger for the first weld.

I LOVE vertical work, and always have. Maybe I'm an adrenaline junkie, maybe I just like being comfortable with stuff that scares the crap out of everyone else. The most fun I've had working was at altitude...

The ones that get iffy are when there's nothing to hang from and your to high for a lift and too far for a crain. So you climb out on the pipes your welding on.Olivero wrote:One day I want to weld something, hanging upside down, and while roped off the side of a building.Otto Nobedder wrote:I LOVE vertical work, and always have.

I've done it ...a lot of it...one time I was underneath a Big ol I beam W 20 or somethin like that. I had to weld the thing together and then fishplate it...full pen welds all the way around. So there wasn't enough scaffold material for the scaffold builders to build a scaffold but this thing had to get done last week. So I hang there by my Drings and do this. When I got to the bottom the helper I had with me asked what my plan was for this part of the adventure. I told him we need a heavy sling and a leather jacket or 2. So I hung under the beam and laid back flat, and told him to throw the sling under the beam and my shoulders and my head and tie it together to hold me up. He tied my feet up around the top of the beam and laid the leather on my belly and chest. Tied my skid lid to the beam in case it would fall off my head with my trusty fibremetal hood on it. 3 hours or so later I was done and very sore and tiredOlivero wrote:One day I want to weld something, hanging upside down, and while roped off the side of a building.Otto Nobedder wrote:I LOVE vertical work, and always have.

Ok, after weeks of practice I think I have a handle on SMAW SS but the stops and starts are going to be my downfall.
I can't cant restart like other rods: strike an arc ahead of the bead and drag it start as that will put a lot of garbage in the weld that will/may surface once I start the next bead. Unless I'm wrong.

"Go as far as you can see and once you are there, go farther."
I do stainless pipe welds all the time and I strike my arc just where I want to start welding, stainless rods work like that, with 7018 I start ahead like you do.
I also travel fast at the beginning to get my starts look smooth if you travel same speed at the start as you do on rest of the bead you get that ugly lump at the start, that you have to grind off.
I hope you can make any sense I am trying to say here, I am very rusty on writing english

FAILED once again.
I took the 3G/4G stainless SMAW test again today and both pieces ended up breaking my heart.
I will not attempt this test again.
Perhaps this is a sign for me to move on from this current gig and expand my welding knowledge more with another company.

You're right, SS can be a mother. One spec of slag can ruin your day. Overhead I long-arced for a nanosecond and it was enough. It left a nice little pocket with a piece of slag. 3G, it was my tie-in which looked good on the surface but the heartbreaker broke it.Poland308 wrote:SS smaw can be a mother! Don't give up if there willing to pay you to test
The company paid for the previous test. I paid for today's test. We are over budget and behind schedule so I doubt my company will pay again. Although it's cheaper to keep me as a contractor will charge $75+ an hour for what SS needs to be welded.
Unless the company wants to pay for another test, I'm not going to bother anymore with it. With the minimal amount of welding left at this project, I'm not sure it's worth for me to stay and NOT be welding.

The PM, Superintendent and I have a great working relationship and already discussed the possible positive and negative outcomes of this last test.
I already knew my job may depend on me passing the test. No pressure there. LOL.
Hey, it's been a good 1.5 years with this company though.

Gentlemen,
My old superintendent was fired. The new guy gave me a new box of test plates to practice stating, "I need you to pass this test. Not only will you save me money but this will set you up for future projects."
So starting tomorrow I will be running practice plates once again.
My question is....
Is there a way to ensure that all of my stops and starts are OUTSIDE of the test pieces? Is it advisable to plan my beads in a way so ALL stops and starts fall outside of the pieces to be cut to bend?
Thank you.

Probably.
The first inch of a typical test plate gets cut off and tossed. The second inch is the one that gets bend tested. The middle two are kept as proof. The 5th inch is also a bend piece or back up, depending on if they are doing 2 bends (root/face, etc.) and the top inch is also discarded.
If you plan your welds to avoid stop/start in the second or fifth inch, you could likely get away with a bad start.
That is what I know of AWS testing. I also did some ASME and ISO stuff on stainless that got x-ray and bend tested but don't know the what/where of the procedures for that type of testing.

Unfortunately, I can only grind the root. Once the root is in and I get a thumbs up, I'm only allowed to use a wire wheel for cleaning.Poland308 wrote:Often no. You will simply need to grind back into your previous weld to ensure a good tie in.

Yeah the tie ins are my greatest concern.Poland308 wrote:The root is the most important. After that the wire wheel should be enough.

If you`re running rutile then starts would be as previous poster mentioned - on the start of the weld.
Rutile ss stick requires tight arc all the time, best is to just practice vertical stringers with no pausing on let`s say 5mm plate with 2,5 mm rod. Amperage for vertical is usually pretty low compared to same diameter rod on mild steel.
If the job allows it you also have rutile-basic electrodes on disposal from Lincoln, which are from my experience great to work with.
