hello everyone and welcome to the X3M TIG channel for today's video we're going to do 6g
it's going to be Inconel uh max tig uh or F34 /F4X uh so the prep
is going to be feather edge uh for the internal cleaning I'm just going to use that carbide
bit clean it like half an inch from that edge from the outside, we're going to remove the mill scale
and uh leave that feather edge
okay that's how it should look nice and clean
it's going to be purged it's a way the backing gas so we don't want any impurity inside
even though Inconel is uh it's not really easy to weld it's a little bit difficult to
manipulate a puddle uh okay now for the gap is 1/8 I'm going to use the bridge rod for
tack uh you can't do any root tacks or bridge tack with you with the wire itself it got to be
gotta be bridge rod so I'm just gonna put one tack on the 12 o'clock and we're gonna flip it uh
flip it around check for the gap if it's even then we're gonna put another tack at six o'clock
okay gap looks good we're gonna put one on the six o'clock
once where the tack is done we're gonna check for the gap on uh two sides or three or nine
o'clock if it's good we're gonna you put whatever the side you like if it's one side uh got a little bit
more gap you can put there just to make it even okay we got three tacks we're going to position in
a positioner you see I got a hole here that's for purge this is where I connect my purge hose so we
can purge that spool I'm just going to tack it in positioner so we can leave it at a 45-degree angle
okay now we got 45 gonna lock it so while the examiner already marked that spool it's uh
that's how he knows that stop so you can't cut it or flip it or whatever so for the filler wire
it's uh Inconel 625 it's a chrome uh it's a Nickle Chrom Moly-3 as you know that
Inconel is a super alloy that possesses high strength properties and resistance to elevated
temperatures so this is my plan planning from On the outside, I'm going to use a 3/32 for the root
playing on the bottom side keep the rod inside and try to keep the rod in that puddle
uh Inconel refers to a group of specific nickel chromium alloys they're using different welding
processes I don't know if you guys have much experience with the Inconel
it's a little bit difficult to manipulate a puddle as uh it's like lots of impurities inside
uh so for the purge I'm gonna go up 30 just leave it together to have nice good coverage
just gonna check I got a nice flow just gonna leave it for a couple
of minutes Inconel is difficult because the welds that are created have a tendency to crack
and you're gonna see it later I'm gonna show you on uh uh on a video it's actually how you get it uh
impurities on the top of your weld and it's uh it's a little bit difficult to stretch okay
that's the plan you can do both uh both things you can do it from the inside like a back feeding
uh free hand I'm gonna use a free hand okay I'm gonna start here the only problem I got here
uh I set up purging 30 but i forget to lower it down so it's pushing my puddle out as you can see
I'm just gonna push a little bit more and then I'm gonna stop I'm gonna lower it down to 15.
okay now I'm gonna cut that tack and I'm gonna grind that stop as you can see there's a little
the way how it pushed outside so I'm gonna I'll have to grind that
grind it out and continue okay now for the continue part preheat and start adding uh
wire try to try to keep the wire in a puddle it's kind of easier, uh but I mean
things changes always so do what you can try to keep it in the puddle
especially on the bottom side all the way once I get up
to 10 o'clock then I might start pulling out and maybe just dip the sides
okay I'm just leaning up the bottom side of the cup inside that groove inside the
just bevel rest my hand a little bit a little bit shaky for this video
so the top part that's what I'm doing I'm just dipping sides
good I'm gonna stop okay now we can uh remove those two tacks on this side
grind all those stops and starts
and you can continue on this side so for this side I try to keep my rode the inside that root
as I said especially on the bottom part you can pull it out slowly once you get up on
up on the two o'clock
just use precaution because the gravity might sag down you have some grapes
that's why I usually like a little bit stronger purge
so it forms my uh root inside a little a bit better especially to prevent uh grapes
it's not that beautiful outside as I said it's a it's a little bit difficult lots of impurities it
actually, it looks like it's because all that uh composition that contains uh that rod
we got a copper got lots of different materials okay the root I forgot to take a shot of the
root a little bit earlier so I kind of have not much room here to make a nice clear shot of the root
already looks good maybe a little bigger on one side but uh that's completely fine as you
can see the root pass from the outside doesn't look really beautiful it doesn't have to be
it's not a beauty contest as long as it's a quality it should be fine that's what I'm
adding right now on the top side I'm just dipping that rod so I'm going to remelt
that little built-up uneven spots that I have on the root pass so make it nice and even
for my hot pass so every other pass fill pass all the way up to the flash it's gonna be easier
for the hot pass I'm uh I'm around 120 at 125
I'm just adding on the sides
as I said I just want to make it up nice and even because that uh outside root pass was a little bit
uneven a couple build-ups and couple a couple few spots okay for the hot pass that's it that's what
I want uh for Inconel it's really important to run a buffing wheel every time every pass
run a buffing wheel if you want to have a clean each pass there are lots of impurities inside
and uh okay so now for the fill pass first pass I'm going to start on on top side
I'm still using a 3/32 rod for hot pass and for this fill pass
amps I think it's 130
okay we're gonna run one on the top and then one on the bottom
and that's what it is pretty much that's the game all the way up to the flash
you just wanna put those uh layers put a nice beads
make it all nice and even all the way to the up as I said clean each pass
now I'm gonna go again on the top side all the way up and then we're gonna
like I go top to the middle and then from the bottom to that uh half of that top pass
and then once you get to the the wider area then we're gonna
then you're gonna have to go like three passes even four depends
I don't know if you can see it here on this shot how actually that uh that puddle actually it's
not easy it's not easy to manipulate it's uh like that impurity inside, it's hard to control
that's why it's a good habit to keep that rod constantly inside that puddle try to
keep it inside as much as you can if you can if not I mean you got to do what you have to do
you can uh still pull it out and put it in and but still kind of that connection is uh it's a little
a bit harder you know every time you continue it's a a little bit to connect to establish that nice flow
okay now I'm using 1 /8 rod from now on I'm going to be using 1/ 8 all the way up to the flash
now it's pretty much it's the game just uh fill fill all the way up cleaning clean each pass
don't go too cold go even up you can go 150 if you want 150 160 whatever you feel like
whatever you feel most comfortable with that amperage, you can handle
okay I did one on the top now I'm going to do the bottom
the way how you feeling you just want to make it kind of even level
if you do the proper steps okay I speed up and now we got a flash fill to flash
three passes pretty much that's what is okay so for the cap
for the cap, I'm using a 3/32 rod and I waited for uh maybe half an hour just to cool down
you know it's easier to put it to start doing cap so 3/32 amps uh 130 walking the cup
try to keep the rod in the puddle as much as you can keep it on the top side of the
puddle and then just uh stretch down keep your line straight as much as you can let that edge
be your kind of guide so you just want to cover and then just follow that puddle that edge
that you got okay for the second pass same thing 3/32 start preheat and uh find those self
you can go half of that you can cover half of that to root but half of that uh first pass but
you don't have to go that wide with that step usually, it's like just cover 25 % of that first pass
as I said you can see like it's uh it's really
it really gives you it's really hard to manipulate that puddle
okay for the third pass same thing try to plan you know calculate how many passes you're gonna need
depends on the steps and how wide you're going how hot you running you can use one eighth rod
I didn't want to go with one eight I'm just 3/32
yeah that's my
third pass clean after each pass
okay and then for the fourth pass for the fourth uh pass of the cap final one
we got a little groove here between that weld and the pipe it's like a little
wagon track here so I'm just gonna dip the reason why I'm dipping here on the top
and not holding the wire inside the puddle is just uh because that little groove I wanna
I'm just trying to be sure that everything is uh melted like a hundred percent and I'm
gonna melt the material and uh and the wire so i can so they're gonna be blended a hundred percent
I mean both techniques are good when you're doing 6g especially on a tig in 99 percent I'm pretty
much walking the cup on my root and my fill hot, fill uh fill cap and passes but uh you
gotta be you just gotta be sure to run hot and do small steps you know any missed steps something you can
you can maybe see it later on at a band test okay that's it for the for the
for the weld, part is down now we're gonna cut all that hard work
it's gonna be nice and cut with acetylene torch
they're gonna cut in uh four pieces then we're gonna grind so you got two roots and two face
okay we got a grind root sides cap
round the edges
don't chase too deep even if you got something you can there's something there's a lot of cases
like there are some spots like porosity but that's mostly from cutting from that torch
they're using it to cut those pieces so though even if you got don't go too deep don't chase it
round edges
and now we're gonna go for band test okay as i said we got uh two roots and uh two face band
okay let's see what's gonna happen to this heartbreaker machine
well if you did the proper steps as I showed in this video shouldn't be worries much
just go nice and slow you know do proper steps and everything should be right
okay first piece looks good second one the same third
and the last one that's it okay thank you guys
uh thank you for watching please support subscribe, like, and see you at the next one, bye!
