HOW TO MIG LIKE TIG WELD (Stacking Dimes) W/ OVERKILLRACINGANDCHASSIS w/ *Tips and Techniques*

what's up guys my name is brad welcome back to another video if you're new to this channel we talk about welding and fabrication cnc machining some fusion 360 stuff and we're gonna dive into some really cool projects so if that sounds like fun hit that subscribe button on this week's video we travel out from colorado to utah to talk with joel and his crew at overkill racing and chassis about how to lay down a beautiful open corner mig weld i'm gonna pass you over to joel rodrigo and alex brown these three guys are going to give you the tips and tricks the techniques to be able to make this possible for you at home so stay tuned hit that like button let's get into it one of the most common questions that we get is how do we make our mig welds look the way that we do we're going to do today is we're going to answer those questions one by one and it's not just a one step solution we've got our prep work we've got the fit up itself we've got voltage settings and there's a couple other little techniques that you're gonna learn from two of the best mig welders that i know when it comes to welding in general there's a lot of people that feel there's a lot of trade secrets when it comes to mig welding an open corner what we're gonna do is pull the layers of that onion back we're gonna give you guys all the tips and tricks that you need so you can weld exactly like rod and alex all right guys so here it is quarter inch open corner joint for your social media shots and you're looking to get something like this we're gonna give you all the tips first things first if you look at this part look at how clean it is it's not a bunch of mill scale it's not all dirty rod what did you do to actually clean and prep this part first thing i did was i hit all sides i mean every single side with the d8 pad and then i took my three inch roll lock disc with a scotch brite and cleaned up all these inside edges so there's no mill scale which just leaves a nice clean weld once you actually get ready to weld the parts so we've got it all prepped up you got all the mill scale removed settings and stuff i mean that's one of the biggest misconceptions you know people are running a real real thick diameter wire we're really only running an 030 diameter wire and it's a lincoln l56 er 70s wire in terms of settings we're running roughly about 18 volts 18 and a half volts and just around 200 inches a minute and uh alex i mean i know you do a lot of pulse spray work if you were to be welding this open corner compared to the settings we would use how much would you change it um well as far as the the layout of the machine it wouldn't be a voltage and a wire speed it would be a wire speed and arc length so the machine setup's a little different the moto transfer is quite a bit different the technique itself is actually pretty similar to what i do whenever i'm trying to get that real nice stack of dimes it's a really different process from what i'm used to and so i can't speak much of the short arc aspect of it but rod did a really nice job on these these look as good as i've ever seen from anyone so i'm impressed so if you look here you actually see that these open corners are tic tac together and the reason i do that is because when you're welding over it you don't get these massive lumps that just make your weld look ugly so i start right here as i come forward i'm coming down making sure my wire is in the center of that joint i come forward a little bit i start coming up and as you come up you see the silica form which is this like brown substance you see here and as it forms you see that it gets darker and as soon as you see it gets darker it's when you start your process all over so with this millermatic 252 we are running o3o wire and 75 argon and 25 co2 as a shielding gas so when i'm welding an eighth inch open corner joint i will be around 16 and a half volts and a wire speed of around 150 to 170. when i weld a quarter inch open corner joint i'm running 18 volts and anywhere between 200 to 220 inches per minute for the wire speed and this is with 0.30 wire so what i'm going to do here for you is i'm actually going to show a visual demonstration basically what rod is talking about so here we're going to use this piece that rod welded on the back side it's a quarter inch open corner like he was talking about and what we're going to be doing here is describing kind of what he was saying but actually on the table itself so if we depict these lines as being the throat of the weld so basically the inside section and these two lines here being the toes which are these edges these are really what you want to focus on if you want to have that nice consistent looking weld so there's a couple of different ways that you can go about doing it some people like to do what's called a whip and pause so what that is is you're actually just moving the puddle straight in between the middle of the throat and the toes and you're pausing for a second and what you're doing is you're letting what's called the deposition rate fill up the joint with filler wire once it's filled to make that nice clean looking bead then you pull back or whip and then you pause again so as you pause again it's going to start stacking them up so there's another technique that people like to use and that rod actually used specifically for this weld here and it's essentially doing a curse of e so what he's doing is he's working his way to the bottom of that toe and quickly moving his way to the top and then pausing just for a brief second at the top and then working his way back down to the bottom working his way back to the top and just repeating this all the way through the entire joint and what that's going to leave you is this real nice consistent looking weld profile as long as your ease are consistent every single time your well will eventually look like this don't be discouraged if you don't get it right away yeah i agree with that there's there's no secret it's just practice guys and just remember this is just a baseline the numbers that work best for rod are going to be different from what works best for alex that are definitely going to be different from works best for me so it's one of those that this will give you a great foundation but ultimately with a little bit of practice you'll be able to fine-tune your settings so you can produce what rod has been producing this whole time guys i hope this tip helps thanks for watching if you learned anything hit that like and subscribe button and until next time
