Tig Welding Flow Rate for Manufacturing SS Welded Pipes

3

no...5!

Can you please elaborate.

Ask not for elaboration, lest ye be asked to elaborate yourself!

Lincoln Electric web site has quite a bit of information, did you try that

Process and Theory

You can look at Miller also. (great machines)

There are a number of factors that affect the required flow rate, not the least of which is the type of gas cup or gas lens being utilized. Flow rates may be procedurally dictated, in which case the type and size of gas cup or lens should also be dictated.

.

A qualified TIG welder should be able to set appropriate flow rates. Novices often make the mistake of continuing to turn up the flow to correct any perceived problems with shielding, but the high flow rates draws outside air in. Flow should be as low as possible but still cover reliably all areas that are at temperatures high enough that exposure to atmosphere is problematic, taking into consideration any external influences likely like gusts, or people walking up.

.

This differs for various alloys. But without further specification, as a rough rule, if stainless beads are consistently no more than light yellow/straw colored, then for many alloys that indicated shielding was maintained until temperatures were low enough.

.

Purging is also something that requires consiideration.

also, is he talking about back purging?........

Who knows.

Maybe?

Questions like this really make me wonder about the number of decisions that are made without a decent understanding of what is standard/correct/important while attempting to not give any hint that some important knowledge is missing.

.

What were the hiring interview like? or, are the people doing the hiring also so worried about not looking like there is something that they don't know, that a little emulation of confidence opens all the doors?

.

....or do I just read to much into a question with insufficient details that fails to fill in those gaps?

like tornado mention, the units just isn't right.... SCFH would make more sense.....

well, because of what it lacks, it seems one has to read something into the question..........

Just to be clear (because rereading, I think I was on autopilot typing that previous comment, and autopilot didn't really make it unambiguously clear)...

...when I wrote 'Questions like this really make me wonder.....' , the type of question in reference was that of the OP and not your question, pheonix911. I'm guessing your got that, but if taken the other way, it seems belligerent and certainly uncalled for.... so I didn't want it to remain hanging out there unexplained.

kg/cm²/min is not a meaningful unit, anyway.

What we have here, is failure to communicate.

again?

Again!

Ti?

What the devil are you talking about?

The question may have been disjointed and vague, but how did you ever come up with Titanium from it???????

Never mind, don't answer that.

Even if they provide a response, it's safe to assume that isn't the question they will answer.

'..._{Rhodium has unique set of factual properties and fanciful properties which makes it ideal for me to spout extemporaniously information that may vary in its veracity but is all unrelated to the question asked. All Rhodium in the universe originated in the relativistic jet sprayed out in the early universe by the galaxy swallowing supermassive black hole called Rhodonodor. Being from such royal lineage, Rhodium is the most pretentious of all the elements. It is better than any halogens, actinides, and rare earth or transition elements, and way better than the remainder. The price of Rhodium has always been to low, which is largely due to jelly haters like that good for nothing Palladium. But Rhodium is resistant to all that pettiness. Everyone desires Rhodium because it has better qualities than any other element. Rhodium is hard and lustrous and inert. Rhodium is tolerating residing in the house of Platinum, until something more suitable is found.}...'

Rohit,

35 surface cubic feet per hour is a good starting point.

You can do the conversion yourself and depending on the specific weld rate and some other conditions adjust up or down.

Don't forget to shield the inside of the tube also.

SCFH = standard cubic feet per hour.

Thanks. Of course. Standard.

TIG welding flow rate?? What flow rate do you really need?? Could you elaborate more??

Do you have WPS/PQR?
