often a ball to a store or shear off and
you'll end up we just slightly prowler
the surface like that and a lot of times
this will be on a machine is something
where you can actually get to the back
of it so I'll just rig this up is a bit
of a demonstration really there are
several techniques for getting a broken
bolt out lout but one of the easiest
ones and certainly one of the quickest
ones is to get a knot of the correct
size put that on there and weld the knot
on the inside and that likely sticks at
a book and stored at a broken bolt and
then it'll help you get it out another
important point is you're far better off
doing this with a MIG welder if you've
got one I'm gonna be using an arc welder
here which is a bit more difficult but
it'll still work all the same but it's
just a bit easier with a MIG welder saw
this video assumes that you already know
how to weld if you don't know it so well
that'll be coming it alerted err so
hopefully so we're going to put the nuts
on there now what we're gonna do we're
gonna get the welders I actually
switched on right now what we're going
to get it we're just going to all the
knots and then we're just going to tack
a bit of a weld on the inside as soon as
we've got a bit of a weld on we're going
to start running devolved around the
inside now an arc weld it's not ideal
for this because it creates a lot of
slag which is going to be included in
the weld bought for this it doesn't
really matter because all's we're
concerned about is getting the damage
ball to the damage thought outs of that
all so what we're gonna do is we're just
gonna wall that I'm gonna switch the
welder on and we're going to whack a bit
of weld in there and till there's enough
well then source a little old and then
we can just get our spanner and we can
undo it when we remove the block and
stored one thing you must do when you're
welding is of course where you correct
PPE so I'm now going to put my visor on
and you should also ensure that you've
got adequate ventilation
whenever you're welding so it's a little
bit difficult for me welding here
because of the position of the camera
and the light but hopefully we'll be
able to get a decent shot of the actual
weld going into the actual not
so as well as welding something to the
top of distort that'll help as we move
it the actually generated during welding
is also going to help loosen the stored
so it's important that you get you not
exactly over the stud where you want it
so we're now going to switch the welder
on and we'll just run a bit of a weld on
the inside of the knot
[Music]
and you can say that that was actually
glowing red out there was that much
eating it so that will hopefully help us
to remove the stud - I'll take our
spanner should now be able to move to
stored and as you can see it has firmly
welded and not to the store well as you
can see that's the actual weld on the
inside of the knot so that's one way to
remove a broken stud
