Frosting Tungsten?

[ascwldr24]

does any body know about bulk liquid argon systems

the preasure should be set at 50 psi according to the flowmeter

could we take the flowmeter out and check preasure with gauge to see if we are getting line drop?

[ascwldr24]

will try that

seems wierd though the tungsten seams to be breaking down as a weld is started

could the tungsten be contaminated
or the gas be bad

[ascwldr24]

My tungsten keeps getting this frosted look to it. What is causing this?

I am using 3/32 2% Thoriated

Argon sheilding at 15 CFH and back purge

welding 316 stainless pipe

root and cover passes seem to have good color cover pass not good looking...

Finally got it!

Little different than i expected but super light.
Any sugestions on sanding to get to fit more comfortable?

[ascwldr24]

Well guys i ordered one yesterday.

I was however disapointed when the man on the phone said i would have to wait 2-6 weeks for it.

[ascwldr24]

Oh i see i have never welded out side with out an auto i didnt know it was bright enough to see with it down. thanks JTMcC ill be askin you lots of questions im trying to get into pipe welding outside. just took my test last week

JTMcC.


How do you use one of these hoods and get it down while staying in position to strike an arc in the bevel?

[ascwldr24]

Do any of you guys use the pancake hood?W ould you recomend the flip front version? Is the wendys pancake a better hood than this one?...

[ascwldr24]

Im using an old hobart looks like a short old refrigerator

It is hard to adjust the amperage on this machine

I hope they have better machines for the test


Justin ill try using that technique is that for hot, filler, and cap?...

[ascwldr24]

Ive been making progress I found a procedure and specs file on lincolns web site its too big to attach
Im haveing trouble on my cover in about the 2-3 o'clock position my bead looks like it is under filled on the top edge of it and rolling on bottom edge if i try to slow down on the top edge...

Hey guys in the next few weeks i will be taking a 6G 6010 7010 downhill pipe test. I have great welding background with tig on pipe but am unsure with stick.
What should i be looking for on root pass? drag rod? Amps?
What size rod is normally used 1/8th?
what should 7010 cover...

?

no not asking because of that video. I am asking because a local utility company posted a job listing saying you would be certified to API 1004 and should be farmillar with it. The shop i work for now we are using ANSI B31.3 I have been told API 1104 is more forgiving than ANSI B31.3...
