Learn Perfect Flux Core Welds In 10 Mins | Gasless Flux Core Welding For Beginners Tips And Tricks |

if your worlds look like this and you want them to look like this stick around welcome to the nightclub guys it's your host the night rancher now i'm in the process of welding about 200 feet of wrought iron for a side project that we have it is big headache and it's very tedious and there's a lot of work to be done but i'm going to be taking a break from that and i'm actually going to be throwing this video out for those of you that are either casual welders or beginner welders that are both using flux core wire and i'm using flux core wire right now and it's actually a really good process and it can actually come out pretty clean if you guys know how to weld it so what we're looking at right here we're looking at four different welds that i just did myself on the exact same machine using the exact same settings and pretty much almost no time uh from each other so i didn't even let the material cool down or anything i went through and did boom boom boom and boom from just looking at the different welds you would assume that i was actually messing with the material messing with the settings on the machine or doing something because this weld doesn't look anything close to any of these other welds and a lot of that has to do with hand controls hand control is basically how you control your mig gun whether you have it too close too far away or you're moving too fast or you're moving too slow the four welds that i have here are all done using very different techniques and we're gonna go through them one by one this first one right here that we're looking at i was way too far away and i was moving the gun forward and back simulating when you have too fast of a wire speed what happens is when you have too fast at the wire speed the wire doesn't have a chance to burn up and and flow in between the weld so it'll bump your gun back when it bumps your gun back you're going to break the connection then you're going to start the connection back up and then it's going to break the connection again what ends up happening is you're going to have a bunch of little balls because every time you break the connection the wire cools down and the puddle cools down so every time you start again you're starting off uh basically from zero and you're trying to warm up the puddle one at a time boom boom boom boom boom and every time you keep doing that you create another ball and another ball another ball and you're also going to notice a lot of spatter around here and in some instances you're going to notice that you're going to lose a piece of the wire because if you're too far away like let's say you're this far away your wire is going to start to get boiling hot and it's eventually going to break off of your gun if it doesn't end up burning up on the material and the rest of the material that doesn't melt is going to be sticking out right here this next weld right here is done at the same height so probably about six inches away from the material but this one has a more consistent wire speed so i'm holding the gun as steady as possible and i'm giving it time for it to flow out and moving the gun as i'm going along but as you guys can see although i am getting heat into the material it's not enough heat to actually make the welding wire actually flow out correctly so the best way to take care of this is since you already know the wire speed is good go ahead and get closer you want to get as close as you can without damaging your actual mig gun so the tip of the mig gun shouldn't be touching the material because a lot of times you are going to weld the tip of the mig gun to the material and if you do that then you're not going to be able to move and you're going to end up having a lot of different problems so you don't want to get it so close that you're that you risk touching it but you don't want to be so far away that your weld isn't flowing out the puddle isn't flowing out this next one right here i'm actually a lot closer probably close to the distance than i'm supposed to be which is a little bit less than an inch so when people talk about stick out they're talking about either a half inch or three quarters of an inch there's really no way for you to keep measuring your stick out as your welding because it's kind of more of an instinctive thing and the three quarters half inch is kind of just like a general rule of thumb for you to have a general idea if you're about two inches away you know that you're too far away you got to get closer so like i said this weld and this well we're done at the same settings and at the same height the only difference between this one and this one is that on this one i decided to go a little bit faster because some of you guys are really scared of burning through the material making a hole in the material and filling up a weld is not very fun so a lot of you guys go through and that you guys as soon as it starts flowing you guys start going and going and going and it doesn't quite not only does it not look right it doesn't penetrate very well if we had both of these going left and right and we tried to break them this one was going to hold a lot better than this one does once you guys start perfecting your welds you guys are going to realize that you guys can't weld without gloves anymore and you won't be able to weld without jackets anymore and the reason for that is the better your welds are the more heat you're putting into the material but also the more heat you're putting on to yourself and in fact up until probably last year i was welding although i was welding with gloves i was not welding with a jacket and what was happening is after my welding sessions i would end up with sunburns on the inside of my arms and so after that i started wearing these jackets these denim jackets or whatever these kind of mechanic jackets are this will protect me from getting sunburns if you are welding like this there's no way your guys are going to get sunburns because you're not producing enough heat you're not putting enough material into your well to do any kind of damage to you or your body the only thing that's going to happen is you're going to have a well that's probably going to fail and it doesn't look very pretty this one also probably won't hold because all the material is sitting on top you've introduced the heat into the material but all the material is sitting on top so you actually got to get closer to make sure the only amount of stick out that's coming out is what's actually being melted if you have a stick out probably of 2-3 inches only the tip is going to be melted and the rest is going to be cold so you're going to be injecting a bunch of cold material into this weld and it's not going to flow out the way you want it to this one right here although we're at the right distance we're moving forward way too fast and also the angle of our gun is probably wrong so the angle of our gun aside from the distance you got to worry about which way the nozzle is pointing so when you're doing flux core if you're starting here and you're ending here you want to make sure that your gun is pointed this way you don't want to point your gun that way and you don't want to point your gun this way the reason for that is as you're welding and you're creating your puddle you're pushing your puddle back so flux core has obviously flux on the inside of the weld and as it's cooling all that flux material rises to the surface and creates what's called slag it's this little layer of metal on top of your actual weld which doesn't look very pretty once you take that layer off it'll just pretty much flake off and it'll look like this nice and consistent you can actually see the ripples in this weld of when i was actually pushing the old well back as i was welding through and you can see where i stopped right there if you point it this way and you try to weld what's gonna happen is you're going to have like your weld is going to kind of want to eat into itself and it's not going to come out right you're going to have a lot of porosity because you're going to trap some of those flux material inside your weld and you're going to create a bunch of holes so you don't want to go behind it if you point your gun this way or that way obviously you're going to be pushing your puddle out that way and your weld is going to come out very crooked it's not going to come out straight so whatever way you're going you drag your weld along that way as well i watch a lot of welding channels and the very popular phrase is if it has slag you drag which means that you are going away from where the puddle is you are pulling the weld towards you you are not pushing the weld because you're gonna have problems so all of these materials do have slag if i take my slack hammer and i hit this you guys can see that there's a little bit of shiny material in there but it doesn't look anywhere near as well as this one does and also the slag is much more difficult to remove because of the inconsistencies in the weld once you have it very uniform and straight it only takes about one one or two smacks and the whole thing just comes off you can just blow it off the rest you can just clean it off with either the rest of the hammer or if you're smart you're gonna be using anti-spatter spray and that's going to coat the entire material in like this oil that will prevent these little balls this little spatter from sticking to your material which will also allow your material to come out very very clean so once you guys dial it in you guys are going to want to look at different products so you guys can do use on it to further increase the quality of your weld so if you guys focus on your hand control you can turn this into this if you guys have any questions post them down below i'll see you guys on the next one night wrencher out
