Welcome to the extreme Tig channel in In today's video, I will talk about roots and show
you different techniques one of the reasons I made this compilation to show you exactly
how to do really in a welding Booth and in the field as this is the toughest part in tig welding
okay we got here two-inch heavy wall it's in a 6G position we're going to use the 1/8 uh
1/8 rod ER70S-6 okay now we're gonna as you can see we're gonna connect preheating both sides
once we establish that puddle then we're gonna slowly progress up the technique I'm using here
is uh just adding that Rod slowly in that puddle keeping uh keeping that rod
50 percent uh inside and outside the bevel
as I'm progressing up just adding adding that Rod as uh or it's a dipping technique it's a
let's say it's basic
another important part when we doing stop starts I want to stop on a start part
you want to preheat preheat size you see that flame I focus more on the sides not
exactly in the middle once it starts melting then you start adding rod as this is the
For the top part you don't wanna you can do a laywire technique but I like to do sides
I like the dip on the sides as uh it's better to control you can control the exact amount that
that you're gonna deposit inside that root same thing when you start on the opposite side
I'm gonna do kind of back feed here technique in the bottom
preheat that start ones start melting keep the rod in the puddle and start melting walls
now I'm doing a free hand here as you can see just uh leaning down the bottom side of the cup
just to keep a little bit steadier but pretty much it's a free hand
as you can see here
I'm back feeding that side
keeping their run constantly inside the inside that puddle
this is how the root looks like
as you've seen in the previous videos okay this is one example 4 inch heavy wall
the same thing in a 6G the only difference here is the tacks you see the position of those tacks
so we got one side without tacks that's the the hardest side for me as I'm a right handed so I
always like to do the harder side first same thing freehand uh loose 1/8 gap one eight rod
start adding rod and then you can uh for one part on the bottom
bottom up to five uh five o'clock I like to keep that rod any constant feed in the puddle
once you're going up at three o'clock to the twelve you want to pull that
rod out and you want to start dipping sides
you want a good preheat and then just go start stop climbing
the amperage I'm using here is a 105.
105 amp amps
I just slow down that video as well so you got a better picture of what's going on
this is how they should look like
so the same thing as I said before every time you'll do starts
you want to preheat that existing weld once you start melting then start start
adding Rod you don't want to focus your tungsten right in the middle
as you might sag down you just want to more focus on the on the sides
no need to push just pretty much keep that uh keep that fire constantly in
that puddle let that tip of that rod be constantly in that melting puddle
you know I have to push you don't want to be a make a build up inside
as I said just uh if you keep 50 50 on an inside inside and outside let's get approximately what I
do and once I get to the top or from uh from let's say from 10 or to 12 o'clock then I keep my keep
my rod outside you don't want to keep it inside the power is okay here we got one horizontal weld
I'm gonna show you the example on the root
there's an uneven gap in this pipe it's a 12-inch carbon
as you can see here because it kind of kind of bigger Gap here uneven it's kind of baby
basically what you want to do here I'm just showing you that you don't
have to manipulate with that wire but you have to manipulate your tungsten
and uh and here it's uh it's a little bit closed so you can actually feed that 1/8
but what we're gonna do we're going to do Keyhole technique we're gonna go right on a high higher on the amperage
once you open open a keyhole add wire Keyhole add buyer
okay I'm gonna show you here now example with that uh with that bigger side of the gap
so I'm holding that rod on the top side of the bevel and I'm just stretching that puddle down
you know you don't really have too manipulate with um
with a wire as well you just keep that wire on the top and let it melt
and just lower that puddle down
the reason why we don't do that because you want to have a even
you want to have it's going to be nice and uniform otherwise all that um excessive
excessive wire and make you build up and uh
that build up is not going to look nice and it might be on the bottom side
okay as I said here we got a little tight Gap so go up on the amperage I
it's around 125 130 amps you want to do Keyhole add wire Keyhole and wire
you can even go harder but just it's easier to control
this is how the root looks like from the outside
or you can take a peek inside to show you how it looks and this is how it should look like if
you just keep adding uh keep holding that rod on the top and you shouldn't have any problems
and this is how it should look like for the hot pass on a horizontal
okay now we got a 5G in the the field we're gonna do back feed
we gotta walk in the I'm gonna walk the cup on that root pass
as I said back feed there's uh just uh to keep that rod inside that inside the pipe
and once you go up at three o'clock or nine o'clock Depends on what side you want
then you can switch okay this is the bottom as you see now we're gonna connect
just pay attention on your on your tungsten stick out you don't wanna
you don't want to have a Tungsten inclusion even though it's really close
it's really close tip of the tungsten and that puddle
but once you dial in you shouldn't have any problems
here I'm just uh doing a constant feed on a back feeding
back feeding technique all the wire inside that puddle as you slowly progress up
this is the result of uh of the back feed it's a nice good root solid
don't have to be you don't have to worry about sag back things like that okay for the tie-in
you always go half-inch feather out a little bit at uh stop- starts for the for better Fusion
it's the same thing preheat your starts
and for the top part as I say I always do I always do dip
dip or a keyhole Keyhole technique once it's open you add the wire open add wire
so now I want to tie in you want to slow down pause a little bit pause on the sides
let it fuse really good and then just go over half inch even further it's not going to hurt
here I'm going to show you this is a this is a free hand so for the free hand the same
thing I'm using back feed technique always always on the bottom to eight o'clock or to
to five o'clock I'm always using back feed technique keeping rod inside feeding
through the pipe holding it in the puddle and slowly going up burning those edges
and all those examples you've seen here in this video that was all a 1/8 rod it was all carbon
so freehand or walking the cup same thing depends
depends what's easier for you but both techniques are good okay here is one old oldie I pulled up
from my archive I'm gonna show you is really big gap this is a jacket we got a jacket uh 90.
it's a really big gap here as you can see it's going to be a little bit different technique
now you're gonna have a synchronized movement with your tungsten and we end
your wire this is how you're building up or doing like a bridge but it's a root
and you slowly closing that that gap while having enough still meaty inside and outside
as you can see here
the
adding one side the other side maybe even the holding through the middle
but it's all about timing and uh just uh once you dial in everything should
be fine just to give you a few few examples in this video working on some new projects
and uh that's it pretty much nothing fancy you know just business as usual
well I hope you guys enjoyed today's video yeah, learned something
new see some new different techniques as I said I'm working on some new projects
and uh more you burn more you learn there's no other way around guys okay and uh today uh I have
a little special guest with me that's my little daughter and uh she's gonna end video for me
If you like this video
give it a big thumbs up thank you for watching guys see you in the next one bye
