[JODY] Hey, Jody here.
-
Thanks for watching
another video
-
from WeldingTipsAndTricks.com.
-
I've got a lot to cover today so
we're gonna get right into it.
-
1f, 2F, 3F, and 4F T joint, all
using the same exact technique.
-
This is part one and part two.
-
I'll also stack a bunch
of beads using a slightly
-
different technique,
and then we'll do a cut
-
net and check and make sure
we penetrated everything.
-
Let's do it.
-
This is the technique,
and basically it just traces
-
the leading edge of the puddle.
-
Flat, horizontal,
vertical uphill,
-
and overhead,
same technique,
-
just traces that
teardrop shape in the
-
front of the puddle.
-
First up is flat,
1F flat T joint.
-
The F stands for fillet weld.
-
So for the flat,
the 1F and the
-
horizontal 2F,
I'm gonna be
-
using a slight pull
angle, a drag angle,
-
and just from that I
know that I'm gonna
-
get some comments saying
that I should have been
-
pushing it, but I'm gonna
keep everything the same here.
-
I'm gonna use the factory
recommended settings on
-
this ESAB Rebel 205.
-
This is the one that does
TIG, AC/DC, as well as MIG
-
and stick and flux-core.
-
And I'm going to use factory
recommended settings for
-
quarter-inch thick steel,
except that I drop the wire
-
feed speed by about 10%.
-
Recommended also is
35% on the inductance.
-
I'm gonna get into that probably
doing some messing around with
-
that later on changing that.
-
I already have done a little bit
of changing and running some,
-
some tests at 100% inductance
on some thin stuff uphill, but,
-
um, for right now, 20 volts, 333
inches a minute, 35% inductance,
-
and I'm gonna be using this
technique, which is gonna
-
keep my arc toward the
leading edge of the puddle.
-
So I'll be watching that,
that tip of that wire and
-
try to make those little Vs,
try to keep that up in the front
-
of the puddle so I can punch it
down into the root of the joint.
-
Again, I'll do the cut and
etch in a part two video here
-
to see how we did on that.
-
With all short circuit MIG
welding, it's important
-
to watch your stick out,
and that's the distance
-
from the contact tip
to the arc basically.
-
And I'm trying to keep that
less than half an inch,
-
three-eighths probably
even better.
-
So take a look at your nozzle
and contact setup and make
-
sure your contact tip isn't
recessed way back up in there.
-
This is about flush.
-
Flush works.
-
I would kind of prefer it
to be protruding just a
-
little bit because on a,
on a fillet weld like this,
-
you can only get in there so
close because of the nozzle.
-
All right, 2F horizontal.
-
It's almost the same as 1F.
-
It's just a little
bit different.
-
It's really no more difficult,
but same exact technique.
-
I'm gonna be tracing the front
leading edge of that puddle,
-
get that arc punched down in
there to get penetration.
-
Same thing,
little bit of
-
a drag angle.
-
I've done lots of videos push
versus pull, and there are,
-
there are definitely
differences, but you
-
can penetrate using either
one with short circuit MIG.
-
Pulling seems to
penetrate a little deeper.
-
When you get into
spray transfer,
-
that's when I would
say push as a rule.
-
You can also pull when you
have to, even using spray.
-
But again, I'm using the little
series of Vs sort of, tracing
-
the front edge of that puddle,
trying to stay up in the front,
-
trying to hold a
short stick out.
-
And I got to mention that
this is probably not the
-
best technique for looks.
-
I have found that it doesn't
look quite as good as like
-
doing a series of cursive
Es or something like that,
-
but whenever I've done
cut and etch tests,
-
this technique has always
been very consistent getting
-
penetration into the root.
-
Now, I'm sputtering
here like crazy
-
And I discovered the reason is
I did not get a good ground.
-
I didn't, I forgot to attach
the ground to a good spot.
-
So basically I'm grounded
here on this little tree
-
And I'm grounded through
a rusty plate and it's
-
transferring through the
table, up through a vice,
-
and that was sputtering
like crazy toward the end
-
because of the ground.
-
So a ground is super
important with MIG welding.
-
That wire's coming out whether
you got a ground or not.
-
For overhead,
a lot of people think
-
you need to turn the
machine down so that
-
it, the bead won't sag,
and I have found that I
-
run it pretty much the same
as I do flat or horizontal.
-
What is really important
though is gun angle.
-
So if I do use a little bit
of a drag angle, I'm not
-
gonna use much angle at all.
-
In fact, after the fact here, I,
I noticed that I was doing a
-
little slight, slight drag
to start with, but then,
-
then kind of transitioned
into a little bit of a push, and
-
then I didn't even realize it.
-
But you know what?
-
Dead nuts straight in,
90 degrees is something
-
really good to shoot for.
-
You don't want to get carried
away with too much push, you
-
don't wanna do too much pull.
-
So shoot for 90 degrees,
you'll be good to go.
-
Once again,
the technique
-
is the same,
just tracing
-
the front edge
of the puddle,
-
and once again
trying to keep my
-
stick out as short
as possible without
-
bumping my nozzle
all over the place.
-
I think the short stick
out probably helps
-
more than anything,
as well as the good hot
-
settings for overhead.
-
So let's do that.
-
Couldn't hardly capture
a good, you know, line of
-
sight here with the camera,
so this is sort of a trailing
-
shot here, but you can sort of
see that I'm using that same
-
technique and I'm trying to
keep a really short stick out.
-
As I mentioned before, um,
on the part two of this thing,
-
I will also stack two more,
at least two more beads
-
on each one of these,
probably a lot more
-
than that actually,
and then we'll do a cut
-
and etch and then we'll
check the root penetration
-
as well as in-between layer
penetration on that video.
-
Now for the vertical uphill,
I am turning this thing down,
-
and basically I'm just using the
next metal setting down for the,
-
from the chart that's on
the inside of the machine,
-
and I'm dropping the wire
feed speed by about 10%.
-
And once again,
I'm sounding like a
-
broken record, I know,
but keeping a short stick out,
-
super important on being able
to punch that arc and that
-
wire down into the root.
-
I ran into that grounding
issue on an earlier joint
-
on the horizontal,
so I've got that bare
-
copper strand of wire in
addition to the clamp, uh,
-
clamped directly to the
piece here, so I should
-
be getting a good ground
from start to finish here.
-
Sweeping that arc right up into
the, into the root of the joint.
-
It looks,
it kind of
-
looks like a V,
especially on the
-
vertical uphill here.
-
But again, I'm just, uh,
a series of upside down Vs,
-
and once again this is probably
not the best way to make the
-
best looking, uh, weld uphill or
any of the others, but it works
-
as far as getting penetration.
-
Just a good go-to technique
if you're in doubt, if you
-
don't have time to practice
and perfect techniques to
-
make everything look great.
-
It's just a good go-to technique
to make a good sound weld, and
-
that's what's most important.
-
Hey, just got some
new TIG gloves in,
-
added them to the store.
-
Black ones, just like the other
ones except black so they
-
don't show so much dirt.
-
Nice then, nice and soft,
no seam on the palm where
-
sometimes it pops open
-
And you get a hot spot there.
-
You could check them
out at WeldMonger.com.
-
That's my store.
-
That's how I support
these videos.
-
See you next time.
