- Welcome to weld.com
Recently, I did a coat detail cut
on a piece of I-beam into another,
and I kind of made a mistake.
And I appreciate you guys kind of
acceptin' the fact that I make mistakes.
But, in any event, we're gonna carry on
with this piece here.
And we're actually gonna, we're gonna weld it
and fill that gap. It's a minor amount of gap.
It's in the flanges. I missed the taper.
And I also had mentioned something
about flanges don't always come in
nice and straight and square.
I'm flush over here on this side.
I'mma hit that corner, but it's kind of narrow over here.
So, I'm gonna show how to fit all that up.
I'm also just gonna rake a slight bevel
across that flange before I fit it up.
I just want to clean it up a little bit,
and we would simulate a field condition,
and we'll weld this without cleaning anything up.
Non-code weld, we'll route it with 6010 and run some 7018.
Sequence of welds, I'll show you that,
so that you can always get to stuff and clean it
with--on the outside flanges.
But, quick little demo here
on how you'd save something like that.
Let's get to it.
I've built a burn bar here not too long ago.
I'm gonna show you how to use it,
or how I use them, anyway.
Go clean this rascal up. I wanna tack these corners up.
I wanna square it this way. I've got a little mismatch
in the flange, but it's not bad.
So, first thing I wanna do is get tacks out here
on the corner so I can still manipulate it.
Okay, so, again I made the mistake
in the cut. So now I'm gonna show you
how you can kind of fill this in
and correct it, or at least save it.
I had pre-beveled the flanges, top and bottom
on the outside up here.
I'm gonna go in here with 1/8" 6010
and kinda route this in a little bit,
fix the little wash into the web here,
and I wanna take care of this gap.
And I wanna bring this over,
and I wanna put a real light route pass in uphill.
Overhead, do the same thing. Come out here and clean it
where I can get to the slag over here
and at least fill that gap in
and get some material in there
and dig deep where I can save this.
Again, this is general structural work.
First thing I'm doing is running a little bit of material
way down deep into the throat of that web
where that gap was, so that when I start my arc
and lightly reach it, I can catch that buildup part
and fill that hole or void.
I've started my weld sequence
on the inside here and laced this up
and blew through on the back side
that the gap and the web to the flange connection.
That way, I could reach in here
and kinda rake the slag outta there.
I'm doing this with 6010s, so I can dig and gouge
and get this form filled in a little bit.
Now, I'm gonna show, 'cause this is filled up,
I wanna come across here with 3/32" 7018
and try to get this weld going
where it covers the route pass with the 6010.
Again, I have pre-beveled this.
So, top and bottom, I would be able to get to this.
The overhead part of it, I could open this up
into clean metal, and finish this off
with 7018 and the flat and the overhead position.
So, I just wanna show this sequence in here.
You can kinda get the picture of how this thing goes,
just to save a Bob's bad beam cut.
I came in here and did this at 100 amps
because I wanted to cover this
and it's in the flat and horizontal position.
I'm not one to terminate a weld out here on the edge.
I try to avoid that at all costs.
If I have to, I'll come out and put a tack
where I can bump into it and blend.
I don't wanna blow that up with a crater.
So, I started here and pushed it up
into the web flange connection up in here,
built my fillet weld, kind of turned the corner.
Now, I've turned my machine down to about 83 amps or so,
and I wanna go ahead and do this fillet weld uphill.
You can get the general picture of how all this goes.
The overhead welding, I would probably start here.
Come into this, make sure I took care of it,
and tie into this uphill weld.
Okay, that'll make me pay attention
a little bit more and not miss that cut.
Again, we went in and we gobbed some 6010
in here on the back side, cleaned it up,
filled this up with a light route pass of 6010,
went uphill, came across, did the same thing,
came back over the top of it
with 3/32" 7018 hot down here,
kind of turned the corner, turned our amperage down,
tied in, got the fillet weld going uphill.
Really no way to get a good brush in there
and really make it slick, flicked up,
but structurally it's there.
We could go in and take a grinder top and bottom,
continue into this precut bevel that we have
and do those welds overhead.
I'm sure you found this educational.
Again, I've gotta admit that I missed that cut.
it wasn't that bad, but it happens.
And that's kinda how you fix it.
So, hope you found this educational.
