🔥 TIG Basics: Fillet Welding Practice

welcome to Welkom a lot of people have asked me about starting out on TIG welding what do i do what do i what do i work on to get started and in our classes you know again I've stated this numerous times it doesn't matter what welding process stick MIG TIG flux core we usually grab a piece of material clean it up we're getting used to the process we're getting used to manipulating the torch the electrode holder or whatever so we run multiple beads I know it sounds boring but I'm telling you it's vitally important because you can run them flat horizontal vertical up and down depending on the process if it'll run up and down you can run some overhead you need to get used to manipulating the torch and everybody thinks well that's the kind of a stupid exercise just running beads yeah really you challenge yourself to run really straight lines you know put that craft into running really straight lines and making clean beautiful beads and then start adding filler wire repeat that whole thing and all those positions of flat horizontal vertical up and down TIG would be vertical up do some overhead stuff because it changes you need to get comfortable that's a whole spin off off into another video people have asked me what do you do to you know have you ever done anything to really kind of exercise for welding think about that for a second you need to be in shape I can tell you I've had I've come home from work being in some really strange positions and they'll thigh muscles are singing and your shoulders are sore because you've been upside down and getting into some goofy places you know maybe some isometrics and some some stretching and all that kind of stuff would help this exercise is just beyond the running bead stuff that we're just going to run a simple fill it well now the exercise comes down to this I have thin material here eighth inch material carbon steel I've cleaned him up nicely with a with a put him in the bead blast cabinet and got him all nice and cleaned up no mill scale on either so the whole exercise is this if I can I'm going to tack these up and I'm gonna run a small bead in here now the bead really doesn't need to be much more than an eighth of an inch okay that's physically fine if you get too big with your bead you will cook the backside of this material you'll cup it you'll destroy it it'll show a bunch of flaky mill scale and stuff like that it may show some anyway but at least the integrity of the material is still straight and I've seen people they they well too either too slow too hot too long of an arc they're doing some really squirrely things and I mean just destroy the backside of this you're pretty much done and you know it it's good immediate feedback another exercise that comes off of this is you can run an edge weld up here on the edge of this eighth inch or 11 gauge material with filler wire and not blow it up okay so if you can do these things and you can control your electrode angle your arc length and your filler wire then you're on the right start and from there we would manipulate things into other joint configurations we do lap welds the reason I like to do fill it well is because we can run multiple beads it can run one for the you can call it a route we run the first one and we'll stack two more just to build it up a little bit again straight lines if you're not used to running straight line same width same height then you're not going to get past this exercise so with just a little bit of material we can make it go a long way and learn a lot of stuff now when I do my lap weld exercises in here I tend to offset the plates slightly and we can tack on the corners and I'll turn them over and start that weld if you start out a lap well if you tack it up on this side and then you start welding on this side you you can get this right here where it draws up off of there and now got a big gap that's never any fun so you know and then if we move beyond that we could take one more piece and stack it up and when we get a lot of weld area that we can go around we try to use efficient use of our material as best as possible another exercise is the outside corner joint we nicknamed it the poor man's bevel you can do these with just adding the filler wire and trying to get the proper crown straight consistency we can add a little bit of gap in them where it welds like a - to pass weld where we get a root and we have to control the depth of fusion on the backside then we come back and run the second beam for a cap try to get you know no undercut on the edges so there's a lot to do but just to keep it simple I want to come in here we want to start this exercise a lot of times when we're tacking these up you can come right down here at the corner and you can you can get these to fuse together real quick if they don't if it looks like it won't jump the art the weld pool won't jump across to the two pieces I'll come in here and just put a dot down and then I'll put this stand this piece up against the dot you can use the magnet there's a couple of things you can prop a brick up here a fire brick or another piece of material anything to hold this steel because you may not get it to talk together just with the ark you may have to use the filler wire imma grab my safety glasses my hood my gloves and I'll be right back so the first thing I want to do when we discussed a couple of different methods attacking up since I'm here by myself and I don't want to use anything getting away of the camera I'm just gonna put a dot on here it goes like this it goes like this when I'm my sure I turned my machine back over to DC I could have been an embarrassing mistake because I never make embarrassing mistakes so I'm back on DC by the way we're using every last DB 200 I'm sorry 200 DB and I'm running off the 115 volt not running off 225 so the Machine maxes at 125 amps which is about what I want on this weld maybe slightly less I am running 116th ER 70s 6 and I'm using pure argon at about 15 cfh I'm gonna put a dot down here to get tacked up you know the other thing I've been trying to do for 44 years of welding is weld without a ground it's never worked yet but I keep trying to do it I hope I use the right into this all right let's see if we can't get this to jump across real quick boom done real quick and then the last thing I like to do is straighten them up nice and straight on there this may have drawn up where there's a slight gap so I need to pinch those together I'm gonna try this in down here without any filler wire just see if I can make it pop across there inspect the backside everything is clean my tacks are over here so my first weld I'm gonna do on this side here we're going to reposition the camera one of the cameras and I want to make this weld over here so we're gonna put a camera back here and see if we can't get an arc shot of this so what it feels like here I mean obviously I'm using the foot pedal but and I can't see the machine but I feel like I'm 120 to 125 amps maybe the camera girl will tell us so I'm using all of what we have set on the machine and that's fine and I'm gonna go about halfway across there clean steel we got a little color in there good it's good now the profile of this weld it's not severely cupped and it's not really convex because I was just adding filler wire on the leading edge but the most important thing about this is the same width same height all the way through there and I turn it on the backside and then my backside is not destroyed it is a flat piece so I get to weld over here on this side too now I am going to weld on this back opposite at this side and I'm gonna try to do this way too hot too long of an arc I'm gonna slow way down make too big of the weld just to show you what's going to go on back here hopefully it'll do it so I slowed down with my travel speed I held a little bit longer of an art and [Music] I put filler wire in like I see some people do just barely put a dab in and I putting it in kind of on the top side this thing is washed out it's like four times too big it's a big old wicked weld I've got a little speck of porosity down here in the crater I haven't even looked at this side over here I hope it's all messed up I did it a little worse than I thought I would do it but that is destroyed it is bad this piece of material is like cut in and melted and it's just you can't weld over the top of that and a way to go back in and clean it so we just created a really bad situation for ourselves but can't continue on so in doing this you get immediate feedback now there's no point in messing around over here to go over this weld we blocked ourselves out of continuing over here but now I want to go back in and stack two more beads on our clean side to finish the rest of the good exercise and then I want to come up here and do one on top just to show you some control one small bead at the bottom we're gonna continue on and do another one at the top ready so we ran there's a couple things here to note we ran one pass down here we went over here and made a bad weld and I'm sure you can see how that's cooked also this is like showing some smoke and stuff but more importantly because I clean these this these coupons in the blast cabinet you can see a blue line or where the heat is crawling out too and I just made these continuous welds too on top of each other so I put three welds over here and it is the same heat ring as this one ginormous bad weld over here so there's a lesson in that much heat you're pouring into it again straight lines same height same width we practice building beads we could keep going and add more beads in here you know there is another method to do this I could come over here on one side and do you know we're just doing holding the same arc length and we're dabbing our material in there it is possible that when we get further on in our skills that we can set this cup in here and teach ourselves how to wiggle or walk the cup along here in either dab or dual a wire again the main thing to keep hammering home here you don't need to make a great big weld to put two pieces of eight inch filler metal or eighth inch stock you but your weld only needs to be about an eighth inch so I've seen people that are trying to start walking out there walking the cup my goodness they're making a great big ginormous weld and you don't need to so you know you can sharpen get the right angle and just barely move this thing back and forth and you can make an eighth to 3/16 well that's just fine and it it pretty much looks the same last weld we want to do is we want to come up here on the top and just see if we can't put a weld up here on top and go around all these edges just to demonstrate some control of amperage and arc lengths and weld pool so we just got a little bead working up here on top main thing is I don't want to blow out the edges I'm just trying to add and build this up a little bit and keep it the same width as the original material so again there's another fun little exercise you can get a lot of welding out of just two pieces of eighth inch material go three sixteenths increase your amperage increase the size of your filler wire go to quarter inch the same thing you can go down although things get a little more critical and you get down thinner material for starting out I think this is a really good exercise I really hope this helps and if you have questions you had some comment I have a lot of people that are sending me pictures of stuff they're working on again clean the material watch your amperage your arc length your travel speed thanks for watching welcome I'm bottom off it with Cali College
