Hello everyone and welcome to the X3M TIG Channel guys I hope everyone is doing good and well
for today's video, I got a 10-inch butt weld it's set up in the position as you can see here
is set up really rigging it's attached to the crane it's about to tack
so I'm just gonna show you a little bit how it's set up it's up on the scaffold
it's a little bit offset that line is gonna show you the closer look I got chain grips
chain grips around with that angle iron just to keep that Spool in place for any High lows
this is a little bit of view from my scaffold deck as I said you see it's secured on
a crane so it doesn't move and stays in place once I got filled to flush that we're going to remove all
their rigging so I got the Gap rolled inside it's a 5/32 it's not really even all the way around
it's okay but it's not perfect there are not much there's lots of room but shouldn't
be big it's not a big deal okay as I said it's uh 5 /32 uh to lose one eight uh on some spots
we're gonna try open up a little bit on the bottom so it doesn't close as I want to do first
tack on the bottom it's gonna be three tacks one on the bottom one on the side and one on the top
then we can remove all that all that stuff around the joint okay this is on the top tack
they all root tacks I got one on the top one on the nine o'clock and one on the bottom six o'clock
as you can see the prep is said it's nice and clean always go couple of inches from that edge
you want to prep his uh 50 of the job you want to have really good prep guys always clean
136 with Miller xmt 136 amps I'm gonna start on the bottom I'm just thinking
about what technique should I use uh should I go walk the cup or freehand or a back feed or
lay wire or combination of everything together
as they got lots of room but still on the sides uh between that tee and the flange and there's
not much room and the standing on that scaffold it's going to be a little bit hard to backfeed
so I'm just gonna I think walk the cup and keep the rod under angle
okay as you can see I feathered out the tack
and now I'm just gonna push that rod in and keep the rod inside for the root
keep the rod connected all the time and
try to have a as last stops as you can so to have nice consistent root
you have to have minimal minimum stops you don't want to stop too much every time
you stop it's visible and then it's going to be uneven spots I've seen a
some of you guys email me and send me your send me your works to see what you guys doing wrong
and this is one of the things I really noticed and lots of lots of you guys lots of stops try to
practice that to have less stops especially on a smaller inch small diameter pipes six inch you
should have only two stops or only on tacks whenever is tack you have to stop of course
like try to practice that that's how you're going to get nice consistent root with less stops
okay this is the bottom the bottom section it's already done this is the root
you know I like bigger heavier root especially at the bottom especially the bottom section
to prevent any suck back as I like to run hot pass really hot
same thing grind stop starts as this joint is going to be x-rayed so I'm just gonna
pay a little bit more attention to it just a little more careful
and I'm gonna switch the dipping technique it's on this side I had a little bit high low
not much but as uh for any high lows I like to use the dipping techniques
dipping rod you can see both sides both edges got burned and you can
see the amount is you're actually putting in so you can kind of control that buildup
just pay attention on your inclination of that tungsten
okay this side already have up to three o'clock it's already done I'm just gonna
Go From Here grind the stop starts and go up to that to the top just gonna stop before
the before the tack on the top okay this is root so far from six to three o'clock
with this root no worries shouldn't be any any issues with it as you can see here only two stops
as I said try to go less stops as you can something to practice
and grind stop starts
just got issue with the lightning but I got really good light setup so it's really bright
okay and I don't know did I mention 1/8 tig filler wire 70s6
and I'm going to stop at the top before the tack
the reason why I'm gonna stop and I didn't do feather out the tack I just want to show
you guys they actually how I'm doing tie-in and you can see here the scratch the scratch start
um do I prefers great start over lifting Arc
I don't know it's it's probably more habit with this scratch start just gotta have that you know
sense you don't wanna you don't wanna Hammer that tungsten in in the root or broke that
tip you just want to scratch it nice it's like a firing the match huh pretty much the same thing
nice and gentle okay now we're gonna feather out uh well I got some a little bit issue with
uh with the breeze coming here, there's a fans close by and that just a breeze coming in
here so I had to put that screen but it looks so okay if you got the lighter you can check
it up always around your joint if any Breeze is coming so you can put some extra protection
and that's it pretty much this is how I do the
feather out tacks for the tie-in
I'm just gonna dip in the middle stretch that puddle before I reach the tack I'm just gonna
slow down and pause you pause a little bit on the sides and then on the other side
and then just adding wire while you're going over and stop right in the middle and the reason why I
got to feather out the way I do it's so I can connect when I'm going on the other side
okay this is the half of the root done half of the spool is finished
yeah it looks alright I like it
okay now on this side I closed the Gap closed a little bit so I can't put 1 /8 inside like if
I if I want to I can I can crank up a little bit more amps I can go dipping
technique the way there is a couple ways I can I can put push that filler wire inside but
just for the purpose of this video I want to show you guys the proper steps don't be lazy
you got tools you got technology use it open up that Gap uh try to leave feather
edges and for feather edge you kind of want to open up under angle as you can see here
you're shaving that uh you're shaving that bevel but you're still leaving that feather edge and
once you got enough now I got loose one eight and that should be good so I can feed Rod inside
as I said bottom section is most important for me I mean it's important all the way around
but I like it have you want to have nice and good start that's always usually on the bottom
if you get nice and good solid root it's easier just just to follow the same thickness the same
build up all the way around okay the same thing keep your Rod inside just gonna work the cap here
keep it Rod inside keep that inclination keep an eye on the puddle you don't wanna
have tungsten inclusion I wanna push tungsten in that puddle too much just stretch it
just feed enough feed enough Rod you don't want to lose you don't
want to lose connections just keep it connected all the time
this is gonna give you a good idea how much build-up you got already inside
as you can see on the side on the puddle you always have to watch how the puddle behaves
okay this is the bottom uh the bottom part
and looks good that's that was the idea that was the goal now we're just gonna continue on
the Gap looks good and even and I'm just going to continue on keeping that Rod inside
while I'm going up around nine o'clock after I reached after I passed the tack
I'm just gonna pull it out slowly from the outside I'm not gonna keep that Rod inside
and the rest of the gravity will do just want to keep it out especially when you're going
on the top, you can switch to dipping or you can dip in the middle and
one two three okay now we reach the top has already did I feather out that the top part
now we're just gonna connect that tie in okay this chilling out a little bit here
I'm just stretching my legs
okay I'm just gonna finish , finish here do the tie in , as you can see uh actually
there's not much you can see from this angle but this is the best I did the best I could
I just dip in the middle stretch one two three deep in the middle one two three this is how you
stretch on the side you know especially on the top uh as I said the gravity will do the rest
you don't have to be worried about a the build
up inside you're gonna have a nice you're gonna have a lot of lots of
protrusion inside buffing wheel clean every pass every time
you want to have everything nice and clean before every pass you don't want to have any impurities
now we're just gonna do hot pass okay same stick out pretty much
up to 10 mil just just a new tungsten nice and clean Sharp
I'm running around 150 amps for the hot pass
pretty simple just keep that rod in the middle stretch that puddle
I'm just gonna I'm gonna finish other side
okay now we got both sides done
same thing buffing wheel and now we're gonna fill to flush probably I'm gonna do two more passes
until it's filled to flush as I said it's gonna be x-rayed so okay now if it's filled to flush
I just used my magic, magic wand
okay at this point we can take that rigging off take it off out
of the crane it was just to hold that Spool in place so just
safe, okay 175 this is what I'm gonna use for the capping yeah I'm gonna switch to the cup size 10.
same stick out for Tungsten up to 10 mil
and just a side to side motion nice rolled that cup from
one Edge to another try to keep the straight edge
it's uh the fastest way if you can walk the cup for your for your capping
especially with the higher amps this rise you already know my story this torch only 150
rated but 175 should be fine I do half of the spool then I let it cool down a little bit
and then I go do other side okay this is for the capping um just keep , keep it
Rod connected keep it in the middle the stretch that puddle
push as needed and that's it pretty much guys uh the capping is done
as you can see I stopped only three times on each side as that there's not much room
between that flange and the joint I have to stop there's not much room to push my head
and that's it that's it for today's video hope you guys like it enjoy it just a little bit uh to show
you what I'm doing in the field world and see you in the next one take care guys thanks for watching
