Hello everyone and welcome to the X3M TIG channel guys for today's video, I'm gonna show you a
slip on flange on a six-inch carbon line I don't know, probably lots of you guys are already
familiar with the slip-on flanges and I did lots of works on them slip-on flange also known as a
huubed flanges have a hub with a very low profile these type of flange is usually connected to
a pipe by one or two fillet welds one from the inside and one fillet from the outside
it's possible to do just a single bead as long as the nice and profile weld
as you can see I got it set up here in a pipe stand I'm just going to roll it out
I'm going to do sections and roll with one hand do some welding just a little tip so
when you tack do small tacks when you tack from the outside, you don't have to tack
inside but it's a good habit if you start welding first from the inside so from the
inside the reason, the reason it's not gonna move it's gonna stay square as it is
but if you do it from the outside it might just go out of square so it's a little
bit it's a good habit so for this I'm using uh 70S-6 1/8
140 - 150 amps for the first pass on a fillet weld is going to be like a first pass nothing fancy
just go nice and slow as I said it's on a pipe stand so I got to do sections just to roll
it with one-handed do weld the section then roll it again I'm going to do this from two passes
as I said this is gonna be the first pass is just a little nice
first pass and then and for the second one just gonna go a little bit wider
for slip on flanges they're mainly used for fluids at low pressure or with a little
risk of leakage it's very common to find these flanges today in cooling water lines
firefighting water lines this is one example of the firefighting water lines or the fire lines
low pressure compressed Airlines and processed lines for substances
such as steam, oil, gas, condensate and it's
good this is the first pass I did
and now I'm just going to do a second pass and once
once you finish inside with the second pass then you can start welding outside
so for the second pass pretty much the same amperage maybe 10 amps up around 150 160.
and just try to go up to the edge of that inside the fillet edge and
that's it pretty much nothing fancy keep it simple it is simple it's nothing fancy just
something I did and don't have in my on my channel yet so I said why not
I know you guys like uh root videos and walking the cup and stuff like that but
it's gonna be a little
video I'm just gonna add to my collection hey as I said nothing fancy keep that rod up on the edge
try to go just up on the top of that edge and just stretch that puddle down
okay try to keep the same , same profile as I said you can do even even one ,one
bead some guys like to stick like 5/32 for example or even 3/16. I don't know I don't rush
I got time I like to do TIG as much as I can even if I got an option to do both and that's it
pretty much uh as I said nothing fancy keep it simple it's not , it's not for auction
and now we're gonna do from the outside so the same thing I'm going to do two passes
first I'm going to do one pass here I can go with a little bit higher amperage of 160.
usually, those lines are even those slip-on flanges are covered with the paint good
habit just try to clean it really nicely, I did on the pipe I did on this edge for the
fillet weld but I didn't do proper cleanup on the top of that flange so that paint is burning and
it's a good habit if you wear a respirator
so the same thing just make a nice good first pass
as I said you can go really hot
that's it pretty much I know some people struggle with fillet welds , they got a hard time walking
the cup or like if you go with a cup size 6 on this one it might give you
a little you know it's not going to be that easy but you can always try a bigger cup
for example cup size 10 or 12 or even 20 depends , depends on the brand
right now I'm using cup 8 on that six inch flange I think that's good enough maybe
I can go with the 10 it'll be probably a little a bit easier but as you can see just go up until
up to that edge and it's a little bit slow process with the tig maybe faster with a stick
but like I like tig as this is a TIG channel and all videos gonna be for TIG pretty much
same thing 1/8 rod as I mentioned before 70S-6
160 - 160 you can go even 170 - 180 amps on this one
and just nice and stretch that puddle make it nice I like to have a nice and good looking bead
from outside, and this is gonna be unfortunately covered in paint a red paint anyway so
that's it, that's it guys for this video I hope you, hope you like it, hope you find
some interesting here thanks for your support so far and see you in the next one, take care!
