Stainless Steel Mig Welding | JIMBO’S GARAGE

Stainless Steel Mig Welding | JIMBO’S GARAGE

welcome to Jimbo’s Garage good afternoon
everyone and welcome back to Jimbo’s garage well today’s video is kind of
short and kind of random let me tell you what we’ve got we’ve got basically a
rectangular gate frame that’s about 12 feet long 6 feet tall and the unique
thing about this is this different than that what I’ve done in the past is it’s
a stainless steel now I’ve never really worked with stainless steel and gate
frames so this is gonna involve some stainless steel MIG welding something
that I’ve really never done before so one thing I want to tell you is
you’re not going to see an installation part of the video at the very end
because that’s out of my hands the owner is just contacted contracted me to build
the frame itself he’s going to be installing some wood slats on the inside
and he’s going to be taking it from there so primarily this video is going
to be stainless steel metal preparation we’re going to talk about the wires that
I’m going to be using the machines I’m going to be using and the settings that
we’re going to use and that’s primarily what this video is going to be about
before we get started I just want to let you guys know that you know Instagram is
a huge platform and it’s a big social media platform and what I do on
Instagram is a lot of behind the scenes or stuff that does not make it to the
channel you’ll catch there you know I’m busy here in the shop all the time doing
something different every single day and just a few things that is worthy of me
of making videos is one thing but all the other stuff that happens in here
that does nominate to the channel is another and that’s what makes it kind of
interesting and those are the kind of things that gets to Instagram so if you
could check me out in Instagram alright let’s get started with today’s video all right so the first thing I’m gonna
do is to start cutting the material and you can see that I’ve set the saw on the
angle of 45 degrees and and just double-checking it with my speed square
sometimes it cuts off just a little bit in just a little bit being off makes a
really big difference on these cuts you can see that it looks like I might be
struggling a little bit cutting this the blade is just starting to get a little
dull and and I know this is stainless steel and it is a little bit tougher but
I did have my share problems here okay well I’m down to the very last cut for
the two-inch square cube right here and I gotta say this blade is burnt I hope I
can make it through this cut right here and then we’ve got some small cuts with
the angle iron I don’t think that’s going to be a problem but I can tell you
this as soon as we get all the stainless steel cut on this thing this blades
going off and you get going in the trash and anyone’s going on this blade doesn’t
owe me a dime I’ve probably had well over a thousand cuts on this and you
know it is on its last legs I just want to finish it up and I’m sure we get this
job done so let’s do it yeah that’s for sure but hopefully there’s a few more
cuts left in this thing and we’ll get this project completed well I got all
the cuts done here and you can see that I’m just taking a ceramic flap disc
right here and I am grinding a bevel all the way around on on these pieces right
here this is some 120 wall thickness stainless and so I want some good
penetration through here I am going to be grinding these wells down flat a
little bit later on this is the look that the the person wanted you some some
tabs or some posts that I had turned down in my lathe for helping with the
fabricating here on my table you can see I put a couple posts on either end at
the table and that makes for a perfect 90 degrees and that makes really for
better fabricating just clamp everything down you’re ready to go all right now
we’re all fastened down ready to start getting welding today we’re going to be
operating off the ACP Pro pulse 200 and I’ve got a spooled up with some III OAL
thirty-five thousand ten pound spool right here pick this up at HTP America
well calm now this is a this is a stainless steel flux core gas shielded
wires that means that we’re gonna be running some gas with this in this case
I’m going to drain some 7525 70% 75% argon 25% co2
I mean running that summer around 40 to 45 cfh for this let me bring in turn the
machine on go through the settings and show the settings we’re gonna be using
and then we’ll go ahead and get started all right so the first thing we’re going
to do is select the program a menu and I’m going to scroll down to the
stainless steel section which is the black right here 308 35 thousandths and
we’re going to be using some 7525 and in the pulse mode we’re gonna go ahead and
add just the one inches per minute probably somewhere right around 300
there 151 amps about 21 volts we’re gonna give that a try and see how it
works all right so there’s the very first tack in the first bead right there
and I gotta say that was laid in there really smooth that was really surprised
I don’t think I’m gonna need to make any kind of adjustments I think I’ll just go
with it just the way it is alright so the first wheel went pretty good I’ve
flipped everything around God everything clamped back down on the welding table
and everything is is perfectly square you can see that the the bevel is a
perfect bevel it’s it’s laid in there really nice this is and being nice and
square this is really gonna make for a good weld in here I’m gonna go ahead and
just tack it right here in front tack it here on the back I’m just going to lay
this in and we’ll see how that looks and then we’ll go ahead and roll the rest of
this thing out but I let’s take a look at this next well all right that lady there pretty good
very little spat or you can just see there’s just a couple little spots on on
here chip the slag off and you can see this
appears to have really good penetration right here we got a good color to it
I think the settings are just about right for what we’re using so I’m gonna
go ahead and well the rest of this thing out and then we’ll go from there okay a
couple things I want to notice may seem like I’m yelling all the way across the
my shop that’s because I am a camera seems like a six miles away but one
thing I wanted to point out that’s that’s important when you’re fabricating
even though that my table is a five foot by 10 foot table and the part that I’m
making a 6 foot by 12 foot obviously it doesn’t fit on my table and it’s very
awkward you know sometimes you get Center supports that go in here and that
still remains on the table and everything stays good but in this case
we’re not having that so you got to do everything you can to get everything up
and level and perfect perfect level is very important when you’re fabricating
you get out of level things get out square very fast so we know that I
perfectly square right here I’m up against the pins on this side I’m
perfectly square on the edge of the table this way I’m hanging off the edge
of the table this way I’ve done a support out here and then I’m going to
show you the minute the other side as well
the other side is hanging off the welding table and it’s important that
that also be nice and level and supported that way everything is is
going to be good and I’ve checked it diagonally for square and it is
absolutely perfect right on the money where it is so I’m going to flip the
camera around I’m going to show you what I’m talking about about having this
thing perfectly level over there and then we’re gonna finish welding this
thing out all right so I’m going to grab a couple of my armor self adjusting
clamps right here these clamps work really good for you know clamping
material together there’s no adjustment they virtually clamp just about any
thickness material and it works out good for and you know stuff like I’m doing
right here which is hanging out the end of the table where I got to kind of
clamp this material together I’m just going to put a couple tacks on it take
that clamp off and I’m able to go ahead and finish my
you see I’ve got the other fixture clamps right there holding it to the
table and those work out pretty good you know the old clamps definitely have
their place that’s for sure so I’m gonna take advantage here and while this part
of the frame is hanging off the end of the table and just you know catch the
inside as much of the welding as I possibly can you know idea I went around
and got all the welding done and now it’s time to grind off everything you
know that kind of bums me out because everything looks so nice and and now
it’s time to start the brushed finish here so I started out with a ceramic
flap just here and went around and ground all the welds down and everything
really looked pretty smooth it’s starting to look pretty good right here
I’m kind of impressed the stainless steels just a joy to work with it really
finishes up nice I went around and got all of it done here this is the rough
finish and once I got all four corners all buffed out here I’m gonna switch
over to the coarse surface preparation disc by Mercer I’m not really certain
how this is going to work with the stainless steel so I thought I would
just give it a try and right out of the chute you could just see a tremendous
difference of the original material plus what we’re doing with this surface
preparation this is a coarse disc so it just kind of left some scratches in
there but it worked out really good once I got that done I switched over to the
scotch brite hook-and-loop system here and went around and just finished this
out and that is really all I needed between the the course and the scotch
brite right here I believe it was a medium the finish turned out just
exactly what I was hoping for pretty cool so that worked out really good for
the frame all the way around and I did want to get that on the inside done
because I am gonna be putting this angle iron right here on the inside and I
needed to have that brush finished on the inside so that’s why I did the
inside of that all the way around so now it’s just time to get the angle iron
welded on the inside and you can see how there’s many uses for these are more
clamps right here you can see I’ve got you know the fixture collapse
in the table and the self-adjusting clamps holding the angle iron and it
works out really good and it just really good for speeding up fabrication you
know it’s been probably almost a year since I’ve had this table maybe not
quite a year and I just reflect back on the days when when I had my small
welding table and how I used to do stuff like this and it just amazes me that you
know now that I’ve got this and all these different clamping fixed your
clamps and regular clamps it’s just so much easier and so much faster
it just makes such a tremendous difference you know times has changed
here in just a little bit less than a year you know I’m cutting 45s for the
angle iron right here to go on the inside I don’t know I probably didn’t
need to do that but I’m trying to make a perfect fit in there and and I got to
say it didn’t quite they weren’t perfect but um but you know close enough and
what they weren’t I just filled in with a weld and after all it’s gonna be
covered up they’re they’re actually going to be building some wood structure
that’s going to go on the inside of this and it’s going to be attached to some
screws or whatever and that’s what the angle iron is in there for anyways
that’s the plan there and you can see I’m just going along here and about two
inch long beads about every foot apart is all we’re gonna need and that is not
going anywhere you know I thought about flipping it around and welding on the
backside of the angle as well but I when I flipped around it just I did not need
that at all if this is this is really strong just the way it is and there’d be
no issues with that well there it is that it’s all complete and all brushed
out and this is a great little project I hope you guys enjoyed the video don’t

  1. Man Jimbo you make everything look so nice, I've never ground my welds before but they sure look nice. I don't weld anything over .25 and I get really good penetration so I suppose grinding them wouldn't hurt. Keep up the great work my friend.

  2. Nice work. I welded some stainless the other day and caused me nothing but problems with going out of shape. It was 50 x 50 x 3 angle 316SS and all I had to do was tig weld a couple of fitting in the middle of a 3m length. Had it held tight but just could not keep it straight using TIG. It would bend like a banana with any heat put into it. Mig would have certainly helped keeping the distortion down.

  3. Muy buen trabajo, limpio y efectivo como siempre.
    Algún día tendré una mesa como la tuya que bueno es trabajar con buenas herramientas.
    Un saludo desde España

  4. nice job there Jim, just one thing I was wondering why you did not have a respirator or n95 mask as the fumes from welding stainless are
    cancer causing because of the chromium , this is what I am hearing so I weld stainless outside to be safe. You always do a great job .

  5. I think it would have looked better on the outside of the 2” if you would have scotch bright it on a forty five degree angle in the corners.

  6. thats weird, I cant find that wire on usa welds site? Id like to try some of it but I dont see it on there?

  7. I bought a Freud Diablo which does steel and SS. It’s not terribly expensive, but it’s a pretty good one.

  8. Nice work. Just FYI stainless steel dust and fumes from welding or heating will kill you over time. Hexavalent Chromium is poisonous. You need to wear a respirator or keep a vent tube very close to the work space.

  9. I have an Evolution saw that is similar to your Slugger. My blades have carbide tips and the instructions say to avoid cutting (even carbon steel) flat as that will overheat the blade and cause the carbide to break off. I know that trying to cut square or rectangle tubing laying it on an angle (cutting with the corners pointing up and down) makes the corner joints a lot more challenging though since you really can't get a miter cut that way.

  10. Nice video.. nice comment and descriptions of your tools .. good explanations.. thanks uncle Jimbo ?
    From Northern Iraq, kurdistan, Erbil

  11. Did you not repassify the stainless after welding? I believe it will rust without doing so. Thoughts or comments appreciated. Nice work by the way

  12. I really dig your videos, and I'm hesitant to even recommend you change anything… but have you ever considered a lav or "lapel" microphone? You could couple that with like a pocket size ZOOM digital recorder and it could make your audio a little better and easier to work with.

    Unfortunately it does add a little extra complication to your videos.. but it might be worth it in the end. 🙂

  13. Jimbo

    Those blades can be oricey. I know that they can re-sharpen carbide wood cutting blades, might be worth checking to see if the folks who regrind/sharpen carbide tpped chopsaw blades could do the same on the Slugger blade? Might get you a back-up blade at the least for a lut less than a new blade


  14. Jimbo, you've got me confused. First off you're mentioning welding gas which in the case of stainless steel is always a tri-mix so 75/25 isn't going to cut in on normal non-fluxed solid wire. Then you're chipping slag off of the weld which indicates that you're using a flux cored wire which has no need for shielding gas. I looked on HTP's site and they don't have a dual shield stainless wire so: WHAT'S THE DEAL?

  15. Stainless does indeed finish up beautifully. About 14 years ago I dealt with a fab shop in Niagara Falls Ontario to make up a sliding jig for a process at work and while visiting their shop I saw a side business the owner has making replacement C3 Corvette frames. They offer them in carbon steel and stainless (natural and polished) The show/demo frame was a completely polished stainless rolling chassis and it was amazing to see in the shop and I am sure even more amazing in the sunlight.

  16. 26,000 views and I was the first LIKE ??

    Come on everybody. Show Jimbo that you like his video and click the like button. It will help him out with YouTubes algorithms.


  17. Hi ?? I want to purchase a industry calculator and cannot remember the brand you have. Is to calculate materials for welding. I will purchase on amazon.

  18. Jimbo, sometimes you add chamfers to the end of your tubing to give room for welding, other times you don't, can you help me understand when to use them and when they can be skipped?

  19. Another nice project!! How’s your 3m speedglas? I’ve been considering buying one for the welding courses I’m taking in the fall. Thanks in advance!

  20. wow I was told to use tri mix gas for stainless its 3 times the cost looks like you going cheap I see that its going to x-ray and a dual shield flux core and running gas ????
