- We've been doin' a series
of pipe welding videos on two inch, Schedule 80.
This one is 6g.
We did the root pass video
and now we're going to do the fill and the cap.
I'm runnin' off an EVERLAST 161 STH,
live arc feature.
Runnin' a 17 series torch, number five cup,
may go to a number six here in a minute.
But, on this fill pass,
you know, on a lot of horizontal and stuff
I tend to weave or if this was larger diameter
and larger groove, I would try to weave
at a 45 diagonal, level with the floor,
keep the wire there on the top edge of the pool.
This one I'll probably just do a straight walk in here
and keep the wire on the top edge, up here.
So, that the bead lays flat with the pipe bevel.
Okay?
Last thing we want is under fill at the top,
and all of our filler metal
down here on the bottom.
I want to be able to see both these beveled faces,
beveled groove in here.
I want to maintain the groove just a little bit.
I do want to bring it up 'til it's almost flush,
but I got to be able to see that
'cause that's my guide when I go do the cap.
Okay?
So, this is the fill pass.
I'll probably get back up underneath here.
Rest the cup in here, gently.
And, try to walk this in.
Just try to gently walk this in here
and get some fill pass.
I'm only runnin' a 120 amps
'cause I don't want to remelt the root pass.
I started out on bottom over here.
A little uncomfortable to start with.
Hadn't been down there in a long time.
I'm gettin' old!
Anyway, we started out and we washed this along here,
keepin' the wire on the top part of the bevel
inside the groove,
so that the bead eventually lays flat in here.
I got to walk it along.
Tryin' to stay out of ole camera guy's way.
But, right about right here, got real,
you know, this is the easy part for me.
So, we got comfortable and we washed this
the rest of the way up.
It's in there to the point
where it's slightly depressed,
but I can still see both of my beveled edges
and I need to use those as a guide.
So, when we come in here and cap this,
I personally, want to try to do a two bead cap.
We want to build this up,
so that we have reinforcement above the pipe.
Then we'll tie the second one in on top,
make sure we don't have any undercut.
All right, I'm going to let this cool off;
get back down to air temp.
We'll be back on it.
I turned things down.
I cooled it off.
After that first bead of the cap,
I let it cool off and everything.
I came over and I cooled it down to a 100 amps.
I felt comfortable with that.
I'm a little...
It was almost a little sluggish on the way up.
It got a little heavy over here at 3 o'clock,
but it blended back in, goin' up to 10, 11 and 12.
So, maybe that was an amperage thing on my part.
Anyway, I walked a two bead cap in here.
This'll get you started.
You practice this a lot, if you do this a lot,
you can fly 'em in there real nice.
When I used to do 'em a lot,
depending on what was around the pipe,
I could either free hand it in there or walk it in there.
This one was a little uncomfortable for me.
I think what we're going to do here is,
we'll probably experiment and get the man cub over here,
and let him do maybe single bead walking cap.
Where we're puttin' the wire clear up on the top edge,
and lettin' the wire fall down,
and we'll get his technique involved, too.
He probably put it in there like an ole golden arm.
We'll see what he's got.
Yo cub, I did a little 6g on the two inch, Schedule 80.
- [Cub] All right.
- The way I did my side over here, I left it a little low.
So, this is what I did, but I did a two bead cap.
That might be a little low.
You want to do a single bead weave in here.
- Yep.
- So, you might have to bring that up a little bit,
or is that filled up enough? - [Cub] Yeah, it's little low.
I'm going to run a fill pass,
then I'm going to run my cap, with 3/32 wire.
- [Man With Silver Beard] 'Kay.
- That's about it.
- All right. Let me grab you some wire.
Hook your ground back up.
Let's get goin'.
(hissing)
- [Cub] I'm just going to sit here
and let that heat up a little bit.
Let my puddle get a little wide,
'cause I'm running at 95 amps.
I'm going to sit here and move it back and forth
before I move forward.
I'm going to put my wire on the top,
the top of the pipe, but inside the bevel.
So, I'm just going to slowly walk it over.
Take my time, stayin' on the inside of the bevel.
I don't want to erase my line, so I won't see.
Just going to take my time.
(humming)
I want to hug to that top side 'cause gravity pulls down.
I'm just trying to keep that top wire.
It starts coming down on me,
I just roll it with my fingers,
when I'm coming back across the wire.
Then I just reposition myself, get off that overhead spot.
Just take my time.
(humming)
Ope!
Stop there!
I slipped!
The reason I slipped, because my angle was too steep.
I should've just kept rotating.
- What'd you do?
Pull a Bob-move there and slip?
Stupid, sticky tungsten.
- Yeah. (laughing)
- It happens. - Yeah.
- You know, especially when you buff the pipe off,
things are nice and slick.
I noticed you used a sanding pad to rough things up.
I also noticed you were,
you had your tungsten barely stickin' out past the cup.
That your angle to keep you under control?
- Yeah, and then in case, I like,
in case, I'm wrappin' around,
comin' around so I don't slip.
If I slip a little bit, I got little chance,
- Gotcha! - of not stickin'.
The reason I caused this, is my wire angle was up too high.
When it's up too high and it's liquid puddle,
it just did the same thing.
So, I need actually keep laying this around
to like 20 degrees.
- 'Kay. So, you're going to come in here, and restart,
and just let that melt.
- Yeah. - Fill that in then, okay.
- If I was going to test with a x-ray,
I would grind this completely out,
- Oh, definitely! - In the tungsten.
But, this is just, we're just practicing,
gettin' back in the groove.
So, Bob, I'm just going to start 'about like,
3/16 square inch back,
so I get my puddle nice and hot,
before I run over that little filler wire right there.
- [Bob] Do it man, do it!
- [Cub] Do it!
Since I'm running so cold,
I want to, basically, just stay still
and just move my puddle up and down
to like the width of it.
Then I'm just slowly run over that,
so a mixture will burn it in.
It just sucked in.
- [Bob] That came out clean. It was just gutter wire.
- [Cub] I'm just keep payin' attention to my angle,
my filler wire.
Keep tryin' to lay it flat while I'm walkin' it over.
Not flat, but 20 degrees.
Too much will cause me to slip back into the puddle.
Basically, we just want to find that sweet spot.
I like, basically, scoot my legs over
without touchin' the tungsten.
I'm just going to walk it up.
(humming)
Nice and slow.
(humming)
I just pause right before the edge of the puddle,
before the edge of the bevel,
because it wants to wash over.
You got to wait a second and it'll come over.
I always try to not put a lot of pressure
on the cup and the filler wire,
because it'll 'cause it to slip forward.
So, I'm just going to, kind of, go up here,
just going to pull right off the center of the pipe.
I'm just going to walk up on yours.
(pop)
And, just pull off.
- [Bob] Okay, we don't want to buff that or slick it up any.
We just want to let it air cool.
- Yeah, air cool. - Use a hand wire
brush on it, if anything.
Actually, there's nothin' in it
except for where you snapped out of it.
- Yeah.
What would you do to get rid of that little eye?
Just take a little file and file that out?
- [Bob] No, I'd use a wire buffer and touch it,
and just clean it up a little bit.
But, there's nothin' in it,
so I wouldn't be alarmed by it.
- Gotcha!
- [Bob] When you commence your cap run,
you want to keep your wire
up here on the top edge.
- [Cub] Yeah.
- [Bob] And, let the filler wire follow the arc.
- [Cub] Yeah.
- Okay. You know, when I'm doin' a two bead cap,
I want to leave enough room for that shoulder,
so I can put some metal in there and control it.
If I'm too tall, it seems like I get real bumpy, real quick.
- Right, gotcha.
- [Bob] Yep, that's a good fill pass.
Got it up there flush.
(snap)
(roaring)
- [Cub] Glad this is a small pipe.
Staying on this bottom too long.
- [Bob] I think bigger pipes are easier.
(roaring)
(humming)
- [Cub] I'm just make sure I'm pausin'
on the long time on that edge, on top.
Now, where I slipped earlier, kind of high right there,
so I'm going to kind of pull a filler wire out.
I'm going to kind of reposition.
I'm just kind of walkin' over that,
until I make sure there's no under cuttin'
on the top of my toe.
Make sure it's blending in all right.
Then I just reapply my filler wire.
(humming)
Make sure I'm just takin' my time.
My puddle's gettin' a little warm,
but you don't have to move it.
So, I'll have to move a little faster,
try to make that up.
Was goin' so slow.
I haven't done this for a little while.
I'm just going to kind of walk this around,
to come into yours now.
(pop)
- [Bob] Cub, nice run, man!
- [Cub] Appreciate it!
- [Bob] Had to fill that up a couple times
and get it up to flush,
before you do the single thing.
You know, again, we did this 6g, we did the root.
We referenced that video.
We did the single fill pass.
I left mine a little low.
I stacked a two bead cap on my side.
Cub come over here and filled up more of what I had.
Brought it up to flush and ran a single bead.
So, anyway, this concludes the 6g
on the two inch, Schedule 80.
Again, you guys practice up on this.
We were runnin' off the EVERLAST 161 STH.
Watchin' our amperage,
you know, the fit.
Things will change.
Experiment a little bit.
You know, guys will run different size filler wires.
They'll have different techniques for fills.
So, easily attainable.
Practice, practice, practice!
Practice 'til you get good!
Then what?
- Keep practicing.
- Drop your hood and practice 'til you can't get it wrong.
- I can hold it. - I'm old,
what's your excuse? (laughing)
We appreciate your support.
(thump)
Stop that! - I'm sorry!

Thanks so much!
- Thank you!
- The camera guy was like, he wanted to be in some spot.
I was shakin' like a puppy poopin' peach seeds.
(laughing) Man, I got rank!
It's not funny! - My legs are shakin'!
