Texas tig

[Memmeddu]

Anyone new looking at this its strongly not advised
This is for anyone new to welding that saw this and thinks it's a good idea

Yes isn't a structural weld, was only to prevent boring noys

 

[Memmeddu]

I think he used a tig rod as extra filler. Not uncommon, pipe welders here do it to fill faster.

Yes i do for this reason because the base metal is 0,9 so i had to put more metal to prevent holes

 

[Hood]

So first question why?
Because i have only 2,5mm inox rods
The base metal is something like 0,9mm and I had to do by using only a buzz box, i have not a tig welder.
Gaps?
There was something like 2mm gap

I do things like that all the time, just takes practice and patience. I do have 1.6mm electrodes but they are a pain to use because they are so flimsy and I reserve them for use on thin tube like you have there but only when there is no thicker metal to be welded to it. In that situation you have shown I would have just used the 2.5's but directed the heat to the plate (which I presume is about 3mm) and then worked from there.
I have been doing stainless for many years so I have built up experience from learning from my mistakes and believe me there were, and still are, many mistakes.
As I said, personally, I don't think it is too bad, just not great and if it got the job done then all is good, but again I am self taught so take my comments as you will.

BTW I am just glad I had Tig today for the bit I have just been doing

Oh you'd be thrown off an oil rig for saying that. If it gets the job done, pass x-ray and UT, then its a job well done.

I’d be chucked off too mate.
If it ain’t on the paper work it shouldn’t be going into a job. Passing NDT tests is one thing but traceability is another. In the event of a failure you cannot have differing welding methods undocumented all over site to get the job done. It might have nothing to do with the failure but if the paper work doesn’t match the actual method or conditions then it’s just a mess for finding root cause and will likely slow things right down.

Yes but you have got to remember we live in world where if something was to happen you would be taken to court and sued we live in where there's a blame there's a clame now days gone by people wouldn't think but now you've got to be careful what you do

Trust me some of the best welders in the world do this and the rigs are still standing.

If the steel is 15mm too short they don’t ship another one out and shut down production for another week.

Procedures go out of the window in the real world all the time mate. Workshop that’s different, you can cut a new piece of steel, gouge a weld out and re-do it.

There’s a reason the best welders are often offshore. It weeds out the chancers.

I'm looking at it as a liability thing no doubt the best welders do it but I wouldn't chance it

I was running procedures for Sapura Acergy in Malayasia for PLEM’s, all the frames we’re heavy rectangular hollow section, we got procedures approved for full pen single sided T-joint with maximum allowable gap of 12mm, this was possible by buttering the face of box section/plate with 3 weld layers maximum, this was put in place to save time and mistakes for fit up, although when non critical scenarios comes along applications like this “Texas Welding” can have it’s place but I would not recommend doing this especially in novice hands!

What is it ?

What is it ?

It is a wear face for the knife of a Spencer Carter slave hauler.

Jeepers Hood! I thought they banned the slave trade quite a while back, even is Scotland...

Nope, as @slim_boy_fat said the other day, we use them to catch the Haggis

15 mm gaps are a regular thing on badly fitted deckplates beams etc due to surveys and misalignment also prefabricated sections and chancer platers they are like joiners eg roughing and finishing breeds
gaps are buttered up both sides with beads of weld 5mm each side then bridged with the root run
on completion of the fill and cap the underside is arc aired back to clean metal and re welded
pipe work is a different story has to be exact fit up.weld parameters audited eg heat inpuuts.ndt .and finaly pmi checked so no shortcuts

 

[Hitch]

Wonder if it would work for big gaps using a MAG arc, and melting a stick rod into it.... great could be great for branch joints in big box.

 

[AndersK]

@Hitch It has been done. If you're on Instagram lookup superior welding. He did that for fun after we had the same discussion about feeding Tig rod while sticking

 

[zeppelin builder]

we used that technique when we run out of oxy. acetylene for welding the rotted out pipes on old quick fit silencers usualy ended up looking like a dormant house martins nest ah poverty the mother of invention aint it !

 

[zeppelin builder]

You can do it with minimal issues if you’re a good welder, don’t let the inspector see you do it though!

You need to go way, way over the normal amperage for the size rod you’re using.

Useful when the fitter has left you a massive gap.

Can’t say I’ve ever heard of doing it on stainless though to be honest.

To me the weld doesn't look that bad but neither does it look too great.
The question though is why was it done that way?
There doesn't appear to be a huge gap that required filling up so I can see no reason not to just weld in the normal manner with a single electrode.
I often have to do repair jobs on boats where there can be a gap, with no way of physically pulling it back together, and personally I prefer just to run beads down either side until the gap is small enough to bridge, then again I am no expert being self taught so.....

here is a typical deck section big gap been out in the salty atmosphere for weeks
lots of cleaning before starting and min 150c pre heat sometimes heating bands too
the platers usualy come away with a good welder would get that
our reply is well you better find one

we work offshore as its one of the few jobs left that pays decent money has a big focus on safety and of course the time off , as for chancers we do get a few slipping through the net. usualy young lads with little expierience unfortunately.
of course they will be given jobs within there capabilities and if they have a decent attitude us old gits will help to bring them on and build there skills .were all in it for a pound so to speak
