Hello everyone, and welcome to the X3M TIG Channel.
So for today's video, guys, I'm going to show you proper steps and things
to pay attention to before I start to welding, especially on the root
as I'm going to show you the root and the steps
with the prep on this 6 inch, sch.40 pipe.
So to begin with, the first thing first
you got to pay attention to is your torch,
your nozzle, your gas lens, shape of your tungsten
collet, this is most important thing before
you even thinking about start welding.
This is what you got to check for.
Any defects.
Impurities can be inside lots of things.
As you can see here, this spattern is like from from any paint on a pipe.
A galvanized you going to have like those spatters inside.
So the gas lens, it's got to be clean that
that's what distribute the gas evenly on your
on your weld pool
nozzle, same thing that's what shields
and protect your weld pool and the collet that's what keeps your tungsten
steady inside and firmly.
You don't want to have any any wiggle parts.
Everything got to be nice and tight.
This is most important. To have nice and clean tungsten
the way how your sharpened, under which angle it all depends from you,
from your personal preferences, depends of the material,
the tungsten on what's the use for all different.
So I'm going to show you here on this syncrowave 300.
This is all good beauty, really nice, good welding machine.
The most important thing is your gas flow for your torch.
This is a 30 standard cubic feet per hour
or in liters should be around 15 liters per hour.
Set up this.
That's what I like to have for my setup and prep pipe.
Most important thing this is this is new pipe.
Didn't clean too much from the outside.
It's good habit to clean at least an inch from the edge.
Tacks root, tacks half inch up two inch long,
nice good solid root tacks so you don't have to take them out.
So you just going to connect to them.
This is going to be your tie in point and start point, whatever you like.
This is
how it should the root tack look like inside.
You should have a lots of meat and
I always like to start from the root connects to another
start from the tack and connect, the another thing except the bevel prep
feather edge someone like land I don't, I prefer
feather edge and a consistent gap
for nice, good, even uniform root.
You need a consistent gap, especially when it's prefab like this
where you've got lots of room and tool and time.
This is around five mil all the way around,
which is good and
so I like to do feather both sides of the tack.
Now this is where we're going to start and connect or this is stop
start tying us and all this both sides feather them out.
So good.
Nice, proper smooth blend connection.
The other thing to pick sides of your rod 332
or one eight as I said depends of your personal preferences.
What do you like what kind of gap some I like 330 to tie
someone like a loose one eight like me in this case or five mil.
As you can see, a big difference between 32 feet inside that big gap.
There's lots of room to wiggle.
It's not going to be consistent that you have to go really slow with low
amperage to do that way to tax both sides.
I like to go with six inch grinders, six inch grinding.
They can do with a five inch. It doesn't really matter.
I got six inch.
That's what I'm showing here.
And I just do it on both sides.
Don't touch the middle.
Middle is where you learn to stop and start.
It's not a rule that you have to stop and start on a on a on a through tack.
You can just go over and start somewhere,
stop somewhere else and start as well.
But just proper steps and habit.
What I like to do and that's why I'm showing you this is where you start
and this is when you start welding, soon as you start melting that
root tack
So the first thing first, once
you initial your first arc,
connect top and the bottom.
This case, it's a horizontal weld.
So I got the foot pedal,
as I said, the max is 200 amps my set up here.
So the root is around 115 right now.
Pay attention to do it.
The bottom is you can hold.
The most important thing is just to hold that rod right in the middle
stretch that puddle, you can see the top is opening.
Definitely.
And then you want to be sure
to burn the bottom edge as well.
Yeah, a couple things here.
Big the size for your nozzle that's going to fit inside
the bevel is going to be easier for you if you want to walk the cup,
if you want to wiggle inside the bevel.
So the
nozzle is good, size is not it's not going to sleep.
There's no any obstacles inside a root and other.
So you can have a really nice smooth path
that you're going to have a nice good control over your puddle.
And the way how you manipulate that torch.
It doesn't really matter where you want the cup, where you will freehand.
Still, same rule should be applied.
All your weld area should be nice and clean and this is the route.
This is good enough made
especially for the hot bass.
Later you can do one pass.
Some guys do like two passes just in case they are afraid of the suck back.
No need for that.
If you got nice lots of meat inside, you shouldn't be worried.
As I said,
I started on a half of that root tack
and so when the root tack start
getting liquid.
This is where you add the rod to try to have the consistent,
consistent move.
So your travel speed
and the way how you feed that rod tried to keep it
always connected.
Yeah, it all depends.
Guys. I know you've got lots of questions about
the speed of your how you feed that rod.
Well, you got to figure that out by yourself.
The way, as I said, that your travel speed.
So that means you have to feed that rod, keep it all
always connected to that puddle.
And that being said,
that's how you adjust yourself both hands.
So when you are keeping that
puddle liquid and you're feeding that rod, that's your travel speed,
that's your speed over your feeding your filler wire.
If you're too slow with your travel speed,
and then you lose that connection, and then you're going to create
gap, you're going to start opening that gap, opening that edge.
That's definitely the one you try to avoid.
That's why your
feeding speed and feeding technique
plays a role here, and that's something
you have to discover by yourself, by welding
and more you.
Weld, the more you're going to learn.
And as I said, you can keep it right in the middle
or you can keep it more to the top and then just stretch that pauddle down.
If you go too cold, you're going to see that it's too cold, too slow.
There's even a possibility you want to even burn edges,
especially on the bottom part and you just going to like doesn't stick,
just glue it, stick it over the edge, not burn it properly.
And then especially if it's tight, you know, guys like lay wire technique on it,
they gap is not really recommended especially guys get sometimes
they go really hot and then over and then they wonder if they got a mistake
and they got, I got tight gap and
I was just running hot but I didn't I got I didn't burn the edges.
I got not enough bend the way that happened.
Well, that happened because you didn't see or what's going on because you were just
running over your wire and you didn't actually see.
Do you have proper edges and did you really burn them or not?
That's why no need to rush special on a root.
Root is most important part in welding.
You want to have nice clean root.
You want to see what's going on
as you can see here before around on the edge of that puddle,
you can see the edges are opening and I'm just holding
with a little bit inclination and I'm pushing away the my tungsten.
You're pushing that
material inside so you got nice
good proper penetration and you should be nice and uniform
and always the also
you can judge by the outside appearance how the root looks like.
That's it for today's guys.
I hope I help you a little bit with
Set up proper steps what you should consider before
and prior start to welding and thank you for your support so far
like and share and see you in the next one. Guys.
Take care.
