Tig welding. Fillet welding. 1mm Thick Stainless Plate Hello. 1mm thick sheet of steel, welded fillet. I’d appreciate it if you could press “subscribe” and “Like.” It’s called “drawing,” “freehand.” This welding method is used to weld the fillet in a rectangular shape. The quality of the weld scene is not good because we’ve enlarged it a lot. Please excuse me. I want to show you the welding scene clean with a good camera. But it’s not easy. Now, this is a welding method that does not separate from the melt pool. Because the camera is in front of my eyes, it’s not easy to do pretty welding. Please excuse me. When welding thin sheets of steel with this welding method… The feeling of supplying the weld rods to the melt pool increases the input heat. And the depth of the penetration is too deep. In that case, we heat the welding rod first. And if you melt the welding rod first and attach it to the steel plate, you can reduce the input heat a little bit. And the depth of the penetration can be a little shallow. The steel plate is 1mm thick. It’s the same thickness of steel that we welded in the previous time. When you do this kind of weld, you can do it the way I just showed you. But it’s not easy to control the amount of heat input or the depth of penetration. So I’m going to show you a little bit easier than this. It’s a spot weld. Now, as I showed you in the video, it’s a little easier to control the input heat. But there’s a fatal disadvantage. And there’s also a pulse welding method that can mitigate that disadvantage a little bit more. The welding setup is spot weld. The current used 100 amps. The welding rod was 1.6 mm. The internal diameter of the gas nozzle is 16mm. Argon gas usage is 20. Welding rods are supplied as if they are lightly pushed in the direction of the melt-pool. And tungsten is aiming at the end of the weld rod. And we’re using a high current to melt the weld rods in a short period of time and attach them to the steel plate The advantage of this method of welding is that it can be welded with very low heat input. And it’s easy to control the depth of penetration. This is a very good welding method for welding thin steel plates. But there’s a fatal disadvantage. If the welder is as crazy as my welding machine, it doesn’t start as well as it does now. Did you see the slow scene? When you start welding like this, you get sparks in the direction you don’t want. That spark could melt the weld rods in the unwanted area. And the downside is that the scar from the spark can be left on the steel plate. Especially at the beginning and the end of the weld… There is a fatal disadvantage that the end of a thin sheet of steel may melt. So, this is how we put the “start button” on and off, and we weld it. The welding rod feels like a light push in the direction of the weld pool And tungsten is a way to aim at the end of the weld rod and weld it little by little. If you want a weld that’s a little smaller than this one, With a 1.2mm weld rod and a slightly lower current, we can do a smaller weld. Now, if you look here, this is the biggest drawback of the welding process. These scars are left behind. As you saw in the video earlier, if you start welding in a direction that you don’t want to see, you’ll have that scar on the steel plate. The maximum drawback. But without these scars, it’s a very good weld. If you weld it with a working welding machine, Can produce faster weld speeds and better weld results I was going to skip this welding procedure. But I thought it would be nice to give you a bad example, so I made a video. Now, this is a pulse weld. There are many different methods of pulse welding. But the important thing about this welding method that I’m about to show you is… Weld the weld rod without detaching it from the melt-pool So here’s how we weld it. Welding rod keeps it from separating from the melt-pool. And the torch is a slow moving, little bit by bit welding. Welding is not difficult. Depending on the situation, you might be able to apply a little back-step like this. Or you can move it a little bit like this and weld it. The pulse setting is ‘1Hz’ and ‘30%’. The current used 70 amps. If the base current or background current is an adjustable welding machine, set it to the lowest level. The pulse setting method is detailed in Part 1 of the Tig welding base, so please refer to it. My explanation may seem a little difficult. But if you learn how to set the pulse, you can weld it very easily. And it can be very useful for welding thin steel plates. And it’s an easy way for the beginners to follow suit. Now I’m welding the weld rods from the weld pool so they don’t detach it. The reason for this welding is that heat is applied to the welding rod first, reducing the amount of heat input from the steel plate. And it’s easy to weld even if there’s a slight gap between the two plates. The result is not bad. It’s an easy way for anyone to follow the pulse setting. Torch movement is simple. All you have to do is move in a straight line like this. It’s simple, right? So today, I’ve been glued to a fillet with a thin stainless steel plate. In the previous video, we did a “Butt-weld.” In the old video, there’s a clip that’s welded without a welding rod. If you apply the welding of these videos, you can weld the thin stainless steel pipe. And you can do a lot of different welding using the thin stainless steel. Well, I hope today’s video helped. My welding method is not necessarily the correct answer. But it’s one of the different welding methods that can be applied in a variety of situations, so I hope it helps. I hope this video will help all the welders grow up and help them a little bit Please press “Like.” If you “subscribe” and come to my channel, there’s a lot more welding videos. Thanks for watching.

  1. 진자 잘 설명해 주시네요 굿!!!
