How To Weld Vertical Or Upwards For Beginners | Gasless Flux Core Welding Tips and Tricks |

welcome to nikola guys it's your host the night wrencher i've been getting a ton of comments people asking me how to weld what the secret is to welding uh flux core vertically so i went ahead and put this demonstration together for you guys i tried filming this at night time but i just couldn't get any good camera angles uh and i ended up welding this real quick just so you guys can see this is just an example it's not anything perfect it's not anything permanent it's just two pieces of scrap metal and i just put them together like this uh this is what people tend to call either a fillet weld i guess you could also call this a lap weld if you were welding it like this it would count as a lap weld but i welded it like this so it is a vertical weld you can tell i do have enough penetration you can see inside there that all the molten metal that turned blue you have one there and then you will have one on the inside corner over here this one over here is just a straight vertical butt weld so you've got the two pieces of steel i think that's 5 8 16 gauge 5 8 you can see that i've got penetration all the way through on this side and a little bit on that side i'm just playing with different versions different techniques to just basically try it out and tell you which one i prefer the main thing about vertical welding and specifically with flux core is that flux core is very difficult to get going because flux core is a harder wire as in it doesn't flow nearly as easily as regular mig wire does because it does have the flux material in it so the most important part when beginning your weld number one is to get it flowing so you want to go ahead and get as close as you can get that thing flowing and the second thing would be to build it up and the reason for that is you want to build it up on the bottom because you're fighting gravity gravity is going to be pulling your molten material down so what you're going to want to do is you're going to go ahead and strike your arc on the p on the metal and then you're going to want to go left and right so you start on one then you bind it to the next one then you bind it back then you bind to the next one because of gravity the spatter does end up falling right here to the bottom and it actually becomes pretty tough to get off the two big differences between the standard phillip weld and the butt welt is how you're going to go ahead and control your gun on the philip weld my preferred process is actually to do a left and right pattern the easiest way that i can tell you guys to go ahead and start your well you're going to want to start at the bottom obviously because gravity comes down if you start at the top you're going to get a lot of porosity you're going to get waves going over your weld and it's not going to bind very well so you always want to start at the bottom when you're welding vertically so you're going to start off at one of the materials then you're going to move your gun to the other material and then once that starts flowing you're going to move it back it'll basically create a nice little molten ball and then after that you just keep going left and right left and right left and right and every time you move left and right you're going to create one of these little waves that's what creates the wave pattern on the weld while i was doing this one specifically i tried it in two different ways i tried it stick a stringer which is basically just straight up and then halfway up i went left and right looking at this the main difference that you guys can see is that when i was doing the stringer weld it was a much thinner weld much less consistent when i went left and right i could control the gun and decide how wide to make my puddle and obviously i can make a better more stronger weld so that's a big reason why when i'm welding fillet welds vertically i tend to go into the left and right motion well that's all fine and dandy but what happens when you're trying to weld something like this so it's almost the same situation except for one thing instead of two flat surfaces touching each other you are fighting with a material that has an opening right here in the front so what happens is because it has an opening it's actually a weaker metal and it'll tend to fall in much easier than this would really it's a little bit more difficult to maintain your heat without actually melting and burning the edge off and causing you to create holes so the best method for welding something like this is that you're actually going to want to start on the stronger material first not necessarily the thicker material but the stronger material aka the material that has the most support in this case right here it'll be nice this nice and flat material so you're going to go ahead and strike your arc right here once you get this thing flowing you're going to touch this and then you're going to bring it back almost instantly that way you can have the two metals bonded and you're just going to keep doing that you're going to touch it go back touch it go back it's not necessarily the same as doing like the s bend that we did up here it's more like this so you want to spend a little bit more time on the stronger material dip into the weaker material then you're going to want to go back and spend a little bit more and what you're doing is you're building up your weld here then binding it to the weaker material building it up over here and then binding it back into the material so if you're looking at it like kind of like this and these are the two materials this is a stronger material and then this is kind of like the weaker material so you don't want to be in a point where you're doing this and when you're doing this you start making a hole right here the second process is a little bit more difficult because unlike the the philip weld over here you don't really have any kind of support so this all really depends a lot on hand control and your gun settings you're not going to want to go too hot because you don't want to poke in and you also don't want to go too slow because you're going to start building a material so what will happen is because it's going vertical you're going to start your weld right in the middle or on one of the materials whatever is easier for you and you're going to shoot straight up you're going to shoot straight up like this so if you go too slow because of gravity it's going to sag it's going to sag regardless and it's going to create all the ripples facing down just like it did over here if you hold it for a little bit more than a second you're going to get a nice big ball right here of basically weld material and it's just going to ruin your entire weld so what you're going to want to do is you're going to want to build up your ball right here at the bottom just like you did on the last one and then you're just going to start pulling it up slowly and if you start noticing that it's balling up a lot or if you're overheating the material climb a little bit further up and then let it build up and then continue on with your stream so the goal here is really to just finish up the weld as fast as you can while also adding enough metal and enough material for it to have a pretty strong weld as you guys can tell here right here i actually did the left and right motion so i actually going left and right right here but i was getting too much build up right here i was leaving the gun in here way too long and on this one i just went straight across it came out more uniform than this one did you guys can tell right here in the back that even though i was going faster and i was going straight up i still put significant amount of heat right here versus going left and right right here and i hardly even put any kind of heat toward here in the back you can see a little bit of yellowing but not much but over here you can obviously tell that i did more than enough heat so i'm going to go ahead and put up the camera so i can show you exactly what i did i'm not wearing any of my protective gear uh unfortunately i do have some like worker gloves these aren't going to do anything in terms of protection maybe they'll protect me against the heat a little bit but hardly anything when you guys are welding it's very important that you guys wear your protection because those burns are pretty nasty they are created using uv rays a lot of people got mad at me last video because oh you didn't warn people that those rays can cause cancer and blah blah blah i know they cause cancer most people should know that they cause cancer i don't like telling people obvious things but i will say it this time because i'm actually not wearing it just because i'm not wearing it doesn't mean that you shouldn't wear it either i just forgot it at work so i'm sorry about that usually i'm pretty careful about wearing my my stuff so let's go ahead and put the camera up and i'll show you what i'm doing visibility is actually key when welding but even more so when you're actually welding vertical you need to see exactly what you're doing and exactly where you're pointing because it will completely determine the shape of your well so basically when you're setting up your posture you want to get pretty much like this close let's assume my finger is a gun you pretty much want to get this close you're going to want to follow along with your gun and see everything the gun is doing see where the wire is hitting and make sure that each motion that you do is deliberate another big issue with us beginners is that we don't know how to set up our machines so we get a lot of interruptions and interruptions when you're welding vertically are actually very destructive what will happen is because flux core takes a while for it to flow out and when i say takes a while it takes a split second but when you're welding a split second can mean the difference between a straight weld and a well that has a lot of balls in it so what you're going to want to do is you want to make sure that you have zero interruptions from start to finish you want to make sure your wire tension is good your wire speed is good in your heat range if anything practice on another material first and then apply the same settings to the material that you're welding here the thickness as long as you're welding the same thicknesses the settings should translate almost identical the only thing that will change is your hand motion if you're not welding holes on a similar material laying down you shouldn't be welding holes on a material standing up if it's the same general size i gotta clean out my helmet because i can't see anything right now flux core creates a lot of smoke and so the inner linings of my helmet actually get pretty smoky you want to make sure you want to keep this all nice and clean so your welds can come out better the better you can see the better your welds are going to get easy does it we're going to look at this world up close in a second okay next one all right let's take a look at these welds okay starting off with the lap weld or the phillip weld you guys can see it's a nice wide weld it did go all the way up but you guys are going to notice that if i hit it with my slack hammer all this slag on top kind of gets out of the way and it actually evens out the weld a little bit because because what you're seeing over the slag is not necessarily the quality of the weld that could just be a pile up of slag and not necessarily a pileup of welding material so i just hit it right now and i don't see any kind of porosity or anything like that and it's just a normal looking weld i could actually hit it with the brush so i can get a cleaner visual on it but as you guys can see it worked just fine i did end up going side to side and then just gently grab and dragged it up this one right here has a similar story but this one as you guys could tell i just dragged it straight up without moving the gun too much so we can go ahead and hit it with the slack hammer [Music] so as you guys can see right here it's got a little bit of a bump to it but not not terrible it's not bad it's pretty flat and it's nice and straight no problems right there i started it off just doing it left and right just to tie in both materials together and i just dragged it straight up they're not the most beautiful welds but i can guarantee that they are strong wells anybody welding like this especially as a beginner is probably doing pretty good with the stuff that they gotta do hopefully you guys find this video helpful i'll see you guys on the next one night wrencher out
