AWS Back Purge Welding Fixture 1

[Music] so we're getting ready to start a very first job of 2019 and I'm very excited and very proud to say that this is going to be a collaboration project that I'm doing from my buddy Jody Collier over at welding tips and tricks comm there's a project that he approached me about a few months ago and I'm very excited to go ahead and get started on it and what we're going to be building for Jody there's an AWS back purged welding fixture so it's going to consist of this big aluminum block right here and it's going to have a couple of steel clamps that are going to be able to pull down and hold two pieces of metal so you can do it but well you know a V joint open butt joint and it's going to have a fitting on here so it will actually back purged are gone through the through the weld joint there so we have a lot of mil and to do on this and I mean we're gonna have some shaper work to go along with this as well we've got a I've got some prints here of all the component parts that's gotta be machined so I'll get you down here so you can see what all we're going to be doing but it's going to be a fun project this piece of brass tube right here that we'll have to drill a bunch of holes in I've got a brass fitting right here that will have the machine will bore a hole through there so this will slip on there and we'll have to solder it on there this would be where you're I'm sorry it'll go kind of like that so beware your gas line hooks to to bring the argon into the block and a couple of clamps two mil so it's going to be a fun exciting project and we're gonna go ahead and make use of our attorney and trekker mil that's been repaired right now we're going to do a little bit of milling over there and I'm also gonna use the shaper to do some shaping over there to get this block flat so let me get you down here we'll go through the prints and then go ahead and get started on it this is the main body of the the fixture here and this is what we're gonna get started on the day this would be the aluminum so all the dimensions are going to be an inch and these are all real simple dimensions there's no real critical tolerances on this thing but like we always do we're going to try to make it as tight as we can and the prettiest we can to within those tolerances there so we're going to be in our block to 12 inches long and it is six inches wide I believe yep six inches wide three inches thick all right and we're going to have to do so we've got a pretty deep pocket that we've got a mill in there it's gonna be I believe it's two inches deep all right we have another section we'll have a slot that's milled through there that our copper block is going to be laying in just like so that'll be where the copper goes right in the middle and we've got our deep slot that's be where the gas comes through is down in there and in this this copper block will have some holes drilled it in as well I'll show you that on another print so this is what we're gonna focus on for now but I'm gonna go ahead and show you the rest of it see the end of it will be drilled and tapped for the fitting to go in there that's where our brass rod will go in alright these are going to be your your two strap clamps that go to the top and this angle on here I want to utilize the shaper and actually cut that using the automatic down feed will set at 30 degrees and be able to easily cut that angle on there versus having to set it up in the mill on an angle an angle plate or tilts in the head this is where the shaper really shines for doing stuff like that but we'll do our slots there in the mill so those are the two clamp blocks this is what the the center copper piece is going to look like right here so we'll have it mill to the right length and a couple holes drilled in the end where it gets bolted down to the aluminum block it has a slot milled in it and then a bunch of holes drilled in it for the investor this is where the gas comes through so this is where right on top of this copper piece is where your weld bead is going to be taking place during the during the welding action all right and in our last piece is our tube this is going to be our gas tube that gets screwed in through the aluminum block you see it's pretty simple we'll just have to cap the end and then drill a bunch of holes and then solder our our bronze fitting on to it all right so there's going to be probably a few videos to to get everything done but we're going to start with this and we're going to utilize both the mill and the shaper to get this - sighs okay so let's go ahead and go get started on it all right so we're over here on the K and T I've got a nice six-inch face mill mounted up in here and these inserts is mounted on this is actually designed for cutting aluminum so we're gonna give this a shot and see how it does I plan on putting the Block in here on the 3-inch wide section and we're gonna mill both sides of that to clean it up and then we're gonna lay it down and we'll side mill with a with a big end mill the ends of it to get those two lengths the six inch wide portion of the block I'd like to do that in the shaper using a sheer tool and show you guys how beautiful that shaper does on aluminum so we're gonna have both the milled and a shaped finish on that I think Jody will like that because he actually loves that shaper and likes to see it in action too so it would be fun for him to have both this and the shaper as part of his project make sure all the dust and chips are out of there no burrs just going to hang it up get our little vise wrench out and go ahead and snug this thing up not gonna take a lot on this we're just kind of skinning it all right come up so we moved it up ten thousands we're going to run 16 inches a minute here oh that actually looks really nice man really nice nice rainbow finish - that did good I think that it's been a long time as I use those inserts but I remember they did really well on aluminum so I think we're just going to leave this side just where it's at just need to follow the edges on it got it clean and deep bird and go ahead and remove it from the vise move the table down [Applause] [Music] [Music] [Applause] looks really good I like it we got our vise cleaned out we've got our parallels in here so to do our side mill and I think it's gonna be appropriate to use a two inch in mill this is a brand new one one that I acquired I believe it was last year I got it brand new 2 inch mill Brubaker still razor sharp so I think we'll use this one to cut in our sides I haven't used this much so I'm having to make sure that our set screws are actually lining up on our flats the way they should so they are there now once I get it mounted in the spindle tightened up then I'll go ahead and make sure that these are snugged up again all right we got our tool tightened up in there good so I got just enough travel to cut this side until the vise coming touches the back so we're gonna be real careful about not jamming it in there and then we'll move it down to this side and just cut the other okay we got about 80 thousands to bring it to a 12 inch swing we're going to try to hit that one really close [Applause] all right using my dro up here 40 pal [Applause] I did really nice that is a nice cut on that thing awesome sweet alright so we'll step it down our 12 inches now and cut the other side [Music] our top is our x-axis there so we want 12 inches that the diameter the cutters 2 inches so we're just going to take it to make sure it's out of the way there we're gonna take it to 14 inches Mike is saying 17,000 is what we need to take off we use my digital caliper so if that's true that's telling me that that in mill is not cut or it maybe it's a read Ryan it's very possible to read round alright so with the calipers for a reference I'm also getting about 17,000 so Mike should be good I checked it what a standard that's on it anyway so we'll just offset this side and cut it and bring it down to 12 inches and look at that we hit it right on the button 12 inches nice all right I'm real happy with how this end mill has cut in the middle perform and so we're gonna we're gonna stop it here for now we're going to go to the shaper and we're gonna use the safer to cut in our six inch wide by 12 inch links they're top and bottom once we get that shaped and we'll come back and then we'll start doing our pocket in here I'll find it helpful to come down gently until I just feel the tool had touched the book touch the workpiece and I set the collar to zero up top and once I get it set to zero which is where it's at then I can just back off a few lines like so and I know that I'll be within five six thousands of touching off sucks there brought it down to lines which would be for thousands total that we're gonna cut and we're going to use a twenty thousand to step over I think that's going to leave a nice finish it will make the cut across there and see how it looks [Music] not 100% sure what all exactly is going on with this but I went ahead and removed the tool I put a fresh grind on it and a fresh home just so that I would know I have a good sharp edge there and we're gonna try it again so foreigner so can beautiful [Music] I got to say that I'm stumped on what's going on with the surface finish there you can see on this side right there it starts off beautifully and some of the cuts through there are very beautiful cuts but I don't know it's got a real funny looking finish to it I mean and I'm I've been watching it it's cutting nice and even all the way across there but it's just not leaving a finish like it's supposed to so I'm just I'm trying to figure this out as I go I haven't cutting aluminum before I cut one time and it did really good and that's why this is surprising me I don't know what what this is going on looking at it it kind of looks like the tools bouncing up but why it would do really good here and then just do it over there on that side I'm not sure it's not to my satisfaction not yet anyway this workpiece you can see when we first start our cut it does beautifully but it doesn't take long to start streaking and I have not figured out why it's actually doing that as it gets across there now I mean it's got a nice finish a fuel to it anyway it's nice and smooth but I don't know what's causing it to go from that to the lines over here I tried slowing it down I'm only running a two towel I tried different depths of cut doesn't seem to matter so what I think I'm gonna do is go ahead and leave this the shape or finish for the bottom side of the of the plate that's going to be the side that gets scratched up you know as this thing's being moved around and slid around on work tables so it's good and square and flat I think we'll just leave that like it is but we're gonna go ahead and you use the ket here to surface the other side which would be the last remaining side there I'm sure to get the chips off of it [Music] [Music] [Music] [Applause] really nice job there looks great I don't feel the step there between the two cuts that really did turn out much nicer than I thought it was going to do and I liked it so much that I'm gonna go ahead and flip this thing over and this will be the bottom and we're gonna do the same cut on the on the the other side there and make it look just like that okay so really happy with it it just manages it's so nice I love it [Music] [Music]
