in a previous video I showed a technique for a root pass along with some purging
tips so that video is strictly on welding the root and I'll link it up
right here if you want to go watch that but now this video is the hot pass and
the cover pass and I'm free handed with a TIG finger here I'll also post a
video pretty soon doing the same joint walking the cup after the root but the
benefits of not walking the cup are you can back up very easily you can go a
little bit at your own pace it's a little bit easier to change electrode
angle on the fly there are some benefits there's also some benefits to walk in
the cup we'll do that later but this video is about free handed with the tig
finger so this is the hot pass only 10 amps hotter than I welded the root. I
probably could have actually welded the route at 105 it just depends on the gap
so I'm doing about the same motion that would be done if I was walking the cup
I'm kind of like doing a Z weave type progression and I'm using the lift arc
setting on the welder so I'm not using a foot pedal and mostly I'm doing that one
for one thing it's just easier when you're doing pipe like this not to have
to worry about having your foot on a pedal and you can pretty much get your
settings dialed in pretty good where you really don't need a whole lot of
adjustment on the amperage the pipe is in a tripod vise so I'm able to just
weld about a quarter of it at a time so it's a little bit easier than you know
going all the way from 6 o'clock to 12 o'clock which is really not that hard
for TIG you're not really fighting gravity like you would be with a
stainless stick or something like that but for the sake of this video I just
thought I'd do a roll out kind of here welding a quarter of a time try to get
some good art shots show the technique and this just about wraps up the second
pass with a hot pass you get a good wire brushing done on that thing let it cool
off to where it's just warm to the touch now we'll do the cover pass still at 105
amps I'm using a number 8 gas lens here today with 330 to 2% lanthanide
electrode probably about 20 cfh on the argon when I do the walk in the cup
video I'll explain a little bit on what difference
cup size makes for that it doesn't make nearly as much difference for this other
than the fact that I would be using more argon I might be getting a little bit
less discoloration but it's gonna wire brush to nice and shiny anyway on the
route pass video some people ask why in the heck I was welding a stainless steel
flange in my shop because as most people know these flanges like this are super
expensive well I got these flanges for free from my friend Roy Crumrine and
I've been meaning to do a pipe welding video like this using them for that so
here is I'm going to make a stand out of this for something either for a vise or
something to hold test pieces while I film videos I'll probably just bolt that
flange to a concrete floor using some anchor bolts or I have a pretty thick
base plate too that's already got some holes drilled in it that I might cut
this off and weld that on so we'll see so that's the hot pass and the cover
pass freehand using a TIG finger all wire brushed and shiny and as I
mentioned earlier coming soon will be a video and walk in the cup on one of
these flanges so we'll talk about cup size some techniques some ways to get
some practice in and whatever else comes up let me leave you with this shot here
this this sort of demonstrates how useful the TIG finger can be i'm prop
and right next to that weld going along nice and slow it's heating up like crazy
but my knuckles are not screaming like they would be if I was trying to prop
without a TIG finger it's my product that's how I pay for these videos 100%
