If you weld such seams under control from the bottom up - of course you need output strips so that the test seam is from the beginning to the end with a uniform bead on the root. And you need a spacer at the back so that the gap does not tighten during welding. The chamfer angle is 30 degrees, bluntness is 1.5 mm. The gap is 3 mm. Voltage is 17 volts, feed is 5.6 meters per minute. Wire is 0.8 mm, Esab 12.51. For filling and cladding, I did 18.5 volts and a feed of 7.5 meters per minute. Gas is a welding mixture. The movements on the root can be both triangles and zigzags as shown in the video. You can also try Z-shaped movements on the cladding, and not as in the video, evenly left and right - a snake. Try different options and you will succeed. If some points in the video are not clear - ask questions in the comments) Average settings will be as follows: Settings for a mixture of 80/20, metal 10 mm: Wire 0.8 mm 4.4 M / MIN - 16 volts - root 7.5 M / MIN - 18.5 volts - filling 6.1 M / MIN - 17.6 volts - cladding Wire 1 mm 3.7 M / MIN - 16.5 volts - root 5.0 M / MIN - 18.5 volts - filling 4.2 M / MIN - 18.6 volts - cladding Wire 1.2 mm 3 M / MIN - 17 volts - root 4.0 M / MIN - 19 volts - filling 3.5 M / MIN - 18 volts - cladding If you want to support the channel - Sberbank - 4276 4000 9663 4390 This will help the channel develop. How exactly? There will be more videos, I will be able to buy something for testing - electrodes of different brands, wire for a semiautomatic machine for testing, as well as consumables for TIG welding. Because the welding channel will not survive for long on enthusiasm alone) #VerticalSeam #BottomUpSeam #SemiAutomaticWelding
