- We've been doing a series of pipe runs
on two inch schedule 80.
We did a 1G rollout and exercise
where we were doing it in quarters
for confidence,
to get you started on some pipe welding techniques.
We're goin' into the 5g where
we demonstrated the uphill well,
we did a 2G horizontal,
today we're doin' the 6G.
I have a standard bevel,
and I clean the inside of the pipe
above the face,
sanded it, wire welded it a little bit
around the edge,
and I probably have maybe a 32nd.
I just lightly hit it with a disc
to kinda take the burr off the bevel face there
so it's essentially a feathered edge.
And I have a 3/32nd filler wire that I can't,
I can almost fit it through the groove.
So this is kinda tight.
Again, feathered edge.
I'm gonna put this on the leading edge
of the weld pool as I come up.
We're gonna shoot off an Everlast 161STH
and I'm using a feature called live arc.
Okay?
And the live arc is,
instead of using a gas valve over here
like on a manual torch,
this is hot all the time
but as soon as I touch the tungsten
to the grounded material,
gas and amperage come up.
I'm gonna run probably with this fit,
I probably wanna go down to about 115,
on my amperage.
That might sound a little high,
but again we got a schedule 80,
and I've gotta fairly tight fit.
I just wanna wash this in here,
keep the wire on the leading edge of the pool,
on account of I feel more comfortable doing that
with the small bore pipe.
Couple of ways to hold the torch.
I don't really wanna stop on the way up,
so I can come in here and hold it like this,
by the way this is not a flex neck,
so I'm kinda rigid,
and in a way I don't like that
because I like to be able to bend this,
and get more straight into the the pipe.
But I could hold it over here like this and come up
which I may do,
I could put a couple of fingers on here,
and come up.
I've seen a lotta folks do that
and do it very well.
I've seen a lotta folks come in here.
I've got a number five cup on here
but in my gap is just almost not wide enough.
And we can wiggle this all the way up
to get us wet, it's your comfort, you know?
Lemme get a ground clamp we'll give it a go.
(flame sparking)
(hissing)
I heat this tack up I come up on the leading edge,
we'll put a little wire in here.
(hissing)
I'm running at 115 amps.
(hissing)
And gently rolling this wire back and forth.
(hissing)
As I come up to this tack,
I take my wire out,
heat everything up,
push some wire in there and blend into this tack.
Then we'll snap out of it.
Okay, so this concludes our root pass run,
6G two inch schedule 80.
I ran off an Everlast 161STH,
I ran 115 amps with my fit,
I ended up holding this,
I wrapped this cable around my arm
and I ended up holding this where I was resting
the heel of my hand so I could get the right angle
in the wire.
It's hard to film these small bore pipes,
it's hard to get the camera guy in here, so.
Anyway, this is the root, okay?
And we're gonna continue on,
we'll do other episodes,
we'll do the fill and the cap,
so I hope this helps out,
I know there's been a lot of questions and comments
about people gettin' started
and they wanna pass this test.
I hope this helps,
if we can help ya out please message us,
put it in the comments.
