welcome back my welcome family once
again here roscendo rodriguez welding
fly dock here at south coast welding
academy in houston texas on today's
video i'm going to be showing you how to
weld on a one inch plate stick out
now ladies and gentlemen this is going
to be on a 1g position
it's a very simple process very simple
techniques
don't want to miss it stick around
all right ladies and gentlemen so come
over here with me and and look at this
so
we have a one-inch plate here
and i need you to clean
the back the front your walls and all
you got to do is just clean about maybe
a half inch
onto your plate all the way around after
that ladies and gentlemen
go on ahead and put a 332 liner
now be very careful because you don't
want to have too much of a landing
remember you're welding on a thick plate
you're welding on an inch plate and it
holds a lot of heat i went ahead and got
my spacer it's a 7018 332 get rid of the
flux bend it and this is what you're
going to use as a spacer so always check
your landing and make sure that you have
a good 332 landing
all the way around
on both plates
all right so first thing first
we're going to go ahead and flip them
have the back side up facing up grab
your 332 spacer stick it inside just
like that
all right nice and even
and all you got to do now
is we're going to uh tack it we're going
to attack it on the very corner
on each side of the plate
small little tacks now be very careful
when you tack your plate
you want a long arc back and forth a
tiny bit not too much and watch your
puddle connect all right so what you're
going to do now you're going to flip
this back to the other side
just like this
and you're going to tack your run-off
tabs
and they're going to go
against your plate on the very edge just
like that
you're going to put a tack
on the very corners just like that
on both sides
now i recommend that you
quarter your tacks quarter them
so that it doesn't pull one direction
okay and i'll show you how to do that
now it doesn't have to be perfect
because these are just run-off tabs okay
all right so ladies and gentlemen now we
have it nice and tacked at a 1g position
and we're going to go ahead and start
doing our route
so what i'm going to do here i'm going
to start warming up my metal
from way back here and then i'm going to
start moving forward so the technique
that i'm going to do i'm going to stitch
forward all right i'm going to go back
out punch on my keyhole put pressure on
it drag a tiny bit
into my gap and then pull it out a tiny
bit go back into my keyhole push
and drag it's a tiny little oval the
angle that i'm going to use here on my
60 10 1 8 i want you to lean
the back part of the rod lean it towards
you 10 15 degrees and then 10 15 degrees
to the right
so we're leading this way we're going to
the right so 10 15 degrees towards me 10
15 degrees to the right
and this is the angle that i want you to
keep it the whole time
now be careful with their keyholes you
see your keyhole shifting then change
your angle adjust it so you can keyhole
right in the center
now uh
watch my angle at all times keep an eye
on it
change it just move it back to normal
right pretty simple
now what i'm gonna do i i stopped maybe
about halfway i didn't have any more
material
we're gonna feather it when we feather
feather your keyhole nice and thin all
right
feather it nice and thin so now when i
restart
i'm gonna go ahead and start warming up
my metal from where i started grinding
so all i got to do is go up and down or
do tiny little circles
moving forward
with the same angle at all times
and as soon as you start keyholing
that's when you're going to start doing
your route you're going to start
applying pressure and you're going to
start stitching
back and forth
doing that little oval technique okay
so always keep an eye on your gap
check your keyhole
uh if you don't have a nice keyhole spot
because you're not pushing enough you're
not penetrating enough so you can turn
on your amperage so that you can blow
through a lot faster a lot easier
watch your gap um if your gap is too
wide or your keyhole is too wide then
you need to stop
change your amp turn it back down so
that you can close your your keyhole
all right so ladies and gentlemen we
just did a root pass now we're getting
into a hot pad before you do your hub
pass make sure you grind down your root
have it nice and clean now we're going
to be doing a hub pass at 130 amps plus
or minus that means it's pretty hot so
be very careful now the technique that
we're going to be using here with our 70
18 1 8. all we're going to be doing is
going from wall to wall pretty much
zigzagging we're going to be zigzagging
and i need you to feel that wall on each
side
on the very tip of your rod
zig zag it zigzag it touch both walls
all the way through
all the way through
all the way through
no rash
speed the whole time
now i'm on my run off tab keep going
keep going
all right so let's go ahead and do our
next pass our next pass is going to be
our fail pass and we're going to be at
130 amps plus or minus
i told it all ladies and gentlemen all
we're doing is going up and down
up and down
it almost looks like circles but i'm
just zigzagging
all the way through
now remember we're leading uh
10 to 15 degrees going forward
and also 10 degrees 10 or 15 uh towards
me the whole time
so what are we going to do now we're
going to keep flushing it out all the
way to the to the very edge and so it's
full but now from this point you can
actually start doing your stringers what
we're going to do here
we're going to have our puddle roughly
an average
okay and meet up halfway of our very
first fill the edge of your putter the
edge of the top part of your puddle the
bottom part of our puddle is going to
roughly bite into our wall now we're
going to do the one on top of it same
concept i'm going to meet up 50
uh at the bottom and then i'm going to
make sure that the edge the top edge of
our puddle
touches the top hole all right first
layer let's go ahead and start doing our
next pass now we're going to do our next
pass our next layer
same concept same idea if you still see
that you can still do two stringers
right next to each other
by all means go ahead and do that as
long as you're not leaving any slag or
or any lack of fusion between them or
any of that any valleys
so
keep everything nice and tight so if you
can do two more on top do two more if
you can fit three then fit three
all right so let's go ahead and start
doing our next pass our next pass is
going to be right on top
this is where it starts to get boring
but be careful pay attention to what i'm
doing here
i focus on my posture focus on my
technique listen to what i'm telling you
keep feeding at all times don't rush
anything
uh proper stacking
all right so
we're moving up now we're actually maybe
about halfway already pretty simple
now i want to tell you something i want
to show you something that sometimes
you know we're not all perfect no one's
perfect
uh sometimes you might see that
you're probably putting more metal on
one side than the other side so
eventually you're gonna start start
stacking or growing uneven
it's not a problem do not worry do not
hesitate
all you got to do is even it out
all right so ladies and gentlemen we're
almost done here so
we're slightly below flush
now
since you're using a 1 8 a 7 18 1 8 you
can actually go ahead and cap it a
little bit under flush
uh the way i always do it i always try
to have it nice and flush
the more flush you are the better cat
your your cap is gonna look
uh sometimes uh you can't tell how much
under flush you are and you're gonna
wanna cap it
and your might your cat might start
looking like this a little bit uneven
but it doesn't mean you can't do it you
can actually so you can actually cap it
slightly under flush
or perfectly flush
now remember how i said before
that if they let you grind then go ahead
and grind any imperfections that you
have this is how you're learning right
this is how you learn and so on so if
the company doesn't want you to do any
grinding then hey i guess we got to be
extra careful right all right so ladies
and gentlemen
now we are done with our fill nicely
flush
and ready to cap so remember you can cap
it under flush slightly under flush or
perfectly flush now if you're allowed to
use a grinder go ahead and grind it
grind the high spots have it nice and
flat nice and even so you can have a
good looking cap one technique that i
like to do
is i always like to grind a line
on my cap now if they don't want you to
use it or well then go ahead and follow
your bevel this is why you're not
covering your bevel whenever you're
doing that that last fill now we're
gonna go ahead and start capping it
now
i have a guideline in there what i'm
gonna do when i cap it
you're gonna have your circle you're
gonna have your puddle i want you to put
your puddle right in the center of that
guideline
all right make sure that you're looking
on top of that puddle
and watch
watch it bite into that top part of your
guideline watch it eat into it okay so
you're gonna see it biting into it
so follow that guideline go nice and
straight try to go uh
at the proper speed at a proper speed
don't rush it don't don't be bouncing
around or any of that don't change your
angle keep the same angle all the way up
always check for lack of fusion make
sure that you're biting into your own uh
your own bevel the guideline that you
placed in there so double check it make
sure there's no porosity
uh no lack of fusion no inclusions and
so on so be very careful once you are
satisfied
right then we can start grinding our
next guidelines all right same concept
we're keeping it nice and simple right
so we're going to drag it again the same
method same way we're going to follow
that guideline
nice and even and nice and straight same
angle what you don't want to do here is
cut any corners and you're trying to
rush this
all right ladies and gentlemen so there
you have it we just finished this 1g
stick out on a one-inch plate it's a
long process it takes time so remember
do it carefully step by step don't cut
any corners and you'll do it right
nothing is perfect ladies and gentlemen
just remember that
practice practice practice now
