(sniffing)
- Yep. That's 2 inch Schedule 80.
Uh, today we're going to do horizontal.
I'm going to do the root pass.
I have the standard bevel,
I've cleaned 'em up, I've put
just barely a whisper of a, a face on there
and that was more to knock the burr off, so
less than a 32nd.
Essentially none what-so-ever.
I've tacked this in two tacks
and the attempt here.
You can hold your torch
and freehand this in
by propping against the pipe
and walking this in, er,
manipulating this in here.
Or, we have the option of
resting a number 5 cup in here
and wiggle or walking this in here.
And this is fit tight enough, I have a
I have a dirty 16th.
This one kind of closed a little bit
so I'm going to use a 3/32nd wire and because
this is tight, I'm going to run 120 amps.
I'm running off of an Everlast
161
STH
and I'm using a, using a feature called Live Arc.
It's just like Touch Start;
As soon as I touch the tungsten
to the grounded material,
gas and amperage come on. I don't have to
use the valve.
So. I'm going to transfer some leads over here.
We'll commence our run.
Uh, this wire may look
white on camera, I don't know
but that's because I've been using
this Scotch Brite on it.
It probably had some processing oil.
I like to clean these wires off
and I just give it a couple swipes with the
the old Scotch Brite.
So, it may look odd to you. I don't know.
I've taken pretty much all the copper of it.
The copper color of it.
Also, a minute ago, I said
holding the torch we can prop fingers
and what not. I'm realizing
that's might be a little uncomfortable for me
and I'm going to try something a little different herein.
And uh, I'm going to hold the torch like this
between my finger because I do that a lot
and I'm comfortable doing it.
And I'm going to just rotate
the heel of my hand across here
while I'm freehanding.
If I get uncomfortable that way,
I'll stop.
All right, I'm coming off my tack here.
I've heated it up.
Pushing a little wire in.
(hissing sound)
I also kind of like to rotate this wire and feel it.
As I rotate wire, it tells me that
I'm hot enough
and I'm pushing on it enough
that it's going in.
I'm coming up to the tack.
So I'm going to heat it up, add wire,
come back a little bit
and weld through it.
By coming up on a long tack
I'm coming up on a mass
and, right before I come out and
snap the arc, I'll long arc this a little bit.
It leaves just a little bit of a depression
but I don't think it's going to suck that hole
all the way through there like
can happen on piping porosity.
Okay, I'm going to rotate this pipe
and show another method of walking the cup.
(hissing sounds)
I'm watching this wire
flow off the end.
It may not look like it's getting in there but
I'm real confident it is, with a feathered edge.
I'm running hot enough
that, um
I'm real confident this is busting the wall down
on the inside.
The question is, is how much actual reinforcment
I'm getting.
I am rotating the wire
and I can kind of feel it going in loose.
(hissing noise)
Pow!
We're hot and smooth.
We hot and smooth.
I'm pretty comfortable with that.
It just looked funny. Again,
I still like the old method of back-feeding
especially on horizontal because I can leave that wire
on the top edge.
But I thought I'd show this tighter, um,
feathered edge type fit here.
That concludes the root run on here
and I've wire wheeled it and it is
pretty smooth.
So.
I'm, I'm pretty confident
but I do want to look at it in a mirror.
Uh, we're going to continue on and do another episode
where we're doing the fill and the cap.
So this particular size tube and groove and everything
on a 2 inch Schedule 80,
more than likely I am going to run a 3/32nd
single bead fill pass.
Try to bring it up flush.
Slightly below. I want to leave my
beveled edges in here and use 'em as a guide.
I'll more an likely run a 2 bead cap as well.
So, be looking for the next episode
when we do the fill in cap.
Appreciate you watching Weld.com.

Let me talk now. I have something in my eye.
Looks like I'm going to bloody cry, man.
Should I say something?
I can't cr.. There's no crying in pipe welding.
It's getting late, man.
You got to turn me loose.
