Tips for TIG WELDING SQUARE TUBING

welcome to Welkom got a quick tip for you today on working with some square tubing this is a eighth inch wall it's leftover material that we did some heavy shelving on in one of the one of the classrooms but it applies to thin walled tubing as well I went ahead and cut a very slight bevel in this because I want to show you fit weld and finish and it's it's really pretty simple and I think this will make sense I have a pretty good saw back here that we and we cut a lot of miters okay it keeps us from cutting caps and sealing things off so when when I fit up square tubing let's say that I'm building a frame rectangular rack whatever it is and I want these square corners I'm fitting this up and I probably do a quick measure with a tape but I don't really care if it's square yet okay the first thing that I want to do here with these two pieces I have a whisper of gap here 1/16 filler wire will not fall through here it will over here in the corner but it will not hear on the point so it's like a 30 second of gap the very first tack that I want to put in here I think we've all done this you talk with TIG or or even meg and man all of a sudden your stuff just moves everywhere so strategically you need to put the tacks in the right place I tend to put mine right up here on very top and the reason I do that is because now I can fit and opening and close this and get this exactly square it really doesn't do anything to the rest of this if I have a good cut so let me get my hood on I'll be right back first tack I'm going to put right in the middle of this [Music] second thing I want to do is go ahead and square it up I want to put two more quick tacks on here so that I don't lose my square and then I'll put a tack out here on the backside two more tax right here in the corner and probably one out here on the very end [Music] now the way I prepared this and the way have we have it fit up I want to finish these welds there's a lot of times when I'm building stuff I don't I don't weld it all the way out I'd you know if something's going to go on top of this plywood for shelving or another sheet or decking plate or something there's a lot of times I'll just weld the inside fill it on the outside and finish this and maybe we have our a heavy angle up right doesn't need to be welded the Phillip weld catches everything is strong so there's there's kind of some ways to think through this anyway I wanted to honor to demonstrate going through the sequence of welds and then finishing it off like this is going to be shown for a frame or something like that even this outside corner over here which I probably have to weld it away from the camera guy I don't know we'll get along in a second so the first weld I want to make I'm tacked both sides I didn't do anything in the in the corner back here I'm gonna check this one more time for square and I'm good and square right on the money actually I don't think it's going to move any when I when I do these welds and then I'll go back and use the flat sander and we'll blend all this in and it's just it should be quality a lot of times on projects like on shelving or stuff that we're doing one frame to start out with and we've got let's say that we've got five or six frames that are going up in a in a big rack build your first one make sure it is really really square talk you some tabs on here and sister all your other parts right on top of it you build one jig is that or one of them as a jig and then you can fly through the rest of these parts so let's start our weld sequence here 1/16 wire if you caught that on camera you'll notice I strike the arc start the arc and go down around the corner I always like to wrap corners do not like to see holes and welds this particular weld has avoided and I'm going to go over the top of it again actually it kind of sunk in I wasn't using enough filler wire since I said we were going to finish this I need to bring this weld metal just up above the parent metal so that we can flats and it won't take long inside fill it and if you caught that on camera I did the same thing it started the art moved it back around that corner one last web it's a nice thing about using the foot pedal I was real low on the amperage because it doesn't take a lot of heat on that particular weld dab that in there going uphill I've got a little bit of a profile to it but I'm not doing a tremendous amount of sanding I'm gonna let this cool off for just a little bit and I'm gonna go do some flapper wheel work and it won't take me very long so I'll be right back okay we're done didn't take long to clean this up I left the square up here I'm looking at a whisper of light all the way up because of the fill it welled in here I could come in and and sand the corner of my tool off but I don't really want to do that I could probably cut this one off it's a cheap one store-bought I do not trust squares for being square I've seen people they'll fit up and they'll be tacking right next to these and get them all hot or nowhere near it but I could probably come in here and that's the same light going up through there so I'm real confident that we're square and then we've got finished product here we're straight we're square we rounded the edges with the same as the the tubing that has rounded edges I could probably do some more finish work that's kind of hard to hit sometimes especially in the corners so you know the whole point is getting fit up square and then finishing the work I tend to do a lot of flat sanding I've watched people that built some decent projects and you'll walk by them after they're painted and they'd like destroyed it with the grinder I mean they have just cut into it they're in a hurry to cut their weld off now if you want to make something good and nice finish everything everything this wood primer nicely and it would paint nicely and it wouldn't show a bunch of gouges so learn to flats and learn to use your abrasives correctly and you know I hope this helps it's more of the project thing square tubing framing stuff pipe tubing cutting miters it's real simple to fit stuff up so I hope this helps out and
