Hello. Today… I’ll do a back-bead welding in the 5G position. I’d appreciate it if you could press “subscribe” and “like.” There are many ways to weld the backbead. There’s a “freehand” or “drawing” way to weld the nozzle onto the floor. And there’s a “weaving” way to weld the nozzle through the pipe. We’re going to do a “weaving” welding today. The nozzle is a large 6. The nozzle has an internal diameter of 8mm. And tungsten length is about 5mm. In the 5G position, it is better to have a shorter tungsten length. Gap has plenty of space even with 2.4mm welding rod. And this is a 3.2mm welding rod. You can still fit in the 3.2mm welding rod The gap is this wide. And the pipes are 100A (4 inches)SCH40 carbon steel pipes. The thickness of the pipe is 6.02mm. I did tack-welding at three, six, nine, and twelve. There are many ways to supply the welding rods. Today we’re going to do a welding process where we’re going to make a melting pool and drag it away. It’s a six o’clock weld. “Overhead” position. The current is 90 amps. Welding rods are used with a 2.4mm welding rod Check the angle and direction of the welding rod. The most important thing in the “overhead” position is that the welding rod should be supplied at the rear of the melting pool as much as possible. That way, we can prevent a little bit of back-bead deflection. Welding was divided into six, seven, eight, ten and twelve. I’ve given you more details at each step. Welding at 7:00. Check the angle and direction of the welding rod. At this angle, the welding rod is supplied. And check the connection. It’s eight o’clock welding. The nozzle is moving diagonally from side to side along the upper matrix of the groove. Check the feed direction and angle of the welding rod. And check the area where the weld was connected. Welded from 8 to 10. When connecting to a service junction, supply slightly more weld rods and separate the weld rods from the melting pool immediately before connecting. Next, stay for a while when it’s connected. Slow down the welding speed and make sure to connect. The next time you start welding again, you create a “keyhole” and supply the welding rod. That way, you can make a natural connection. Check the connection and the connection. This time, welding is from 10:00 to 12:00. Move the nozzle diagonally from side to side. Keep the welding rod supplied at the back of the melting pool. And when connecting to tack welding, please supply a little more before connecting. And remove the welding rod. Then pause for a while and then slowly move and melt the tack welds securely. That way, you can make a natural connection. And at the end, hold the crater. These results come out. Please check the connection. So, we’ve arranged the back bead welding in detail. Some of you were wondering how to supply the welding rods. This is the supply method that I use. I’m “Daddy Fingers,” “Mommy Fingers,” and “Brother Fingers.” I use three fingers like this way This method allows continuous supply of welding electrodes without interruption. And it has the advantage of speeding up the supply speed. But there’s also a downside to the fact that the end of the welding rod is shaken by the absence of a support. Now I’ll show you in a continuous motion. The current has been raised to 110 amps. And the rest of the conditions are the same as before. Look at the position of the head and the movement of both hands. It is recommended that the head is always in front of the melting pool. And the torch moves diagonally from side to side. If you use your wrist together, you can make a softer motion. And keep the welding rod supplied at the back of the melting pool. When connecting to the tack welding part, pause for a while and proceed slowly while melting the tack welding firmly. Next, make a keyhole and supply the welding rod. Then you can make a natural connection. As I’ve said in other videos, it’s been so long since we haven’t had this kind of weld, we’re not as weldable as we used to be. It’s an excuse anyway. I’ll practice whenever I can and try to show you better welding in the future. Today, we’ve arranged the back bead welding step by step. I’ve made it as detailed as I can understand it. There are many other ways to weld the backbead. Keyhole, half-keyhole, penetration welding, etc. We’ll make a video of that in the future. As I always say, my welding method is not necessarily the answer. But it’s one of the welding methods that we can apply in a variety of situations, so I hope it will help. I hope this video will help all welders grow motivated and help a little bit. Please press “like” If you “subscribe” and come to my channel, there’s a wider variety of weld videos. Thanks for watching.
