Will the current and voltage be adjusted? If it can be adjusted, the current during vertical welding should be smaller than that during horizontal welding. Of course, it also depends on your personal mastery. You should know one thing: What is the correct current and voltage? The so-called current and voltage means that the welding wire can be fully dissolved after the voltage comes out. The current and voltage of vertical welding are on the correct basis, and the voltage is slightly greater than the correct value. 1: Clean up the vertical welding position {pay attention to grease, welding slag and water =} 2: To know the size of the welding angle to be welded, first burn a standard welding angle according to the size of the welding angle. Note that high quality welding must be from bottom to top! 3. Start arc striking with standard welding angle. When the welding wire swings left and right, be careful not to go beyond the scope of the molten pool (formed by the complete dissolution of the welding wire). When swinging from side to side, both sides pause, depending on the welding angle. If the welding angle is too large, it is recommended to weld several times. Generally, it is easier to weld under small spots for the first time. If it is too big at one time, it is easy to have insufficient thickness, ugly appearance and protruding sides. When swinging from side to side, it is necessary to control the rhythm, weld up slowly, and pay attention to steady hands, which is a necessary prerequisite for high-quality welding. 4. Method of crossing the anchor point: There are many methods, and here I mainly tell you two: direct transition method, which requires a high degree of personal mastery. When welding to the anchor point, swing directly and burn upward. Be careful not to stop quickly in the middle, just transition naturally, and the stay time on both sides depends on the individual. Pay attention to fast transition, insoluble anchor point, easy to fry and weld, and wear protective clothing. Two: spot welding transition method, when welding to the anchor point, stop and swing left and right twice as a round trip, spot welding transition to the anchor point and continue welding. 5. At the end of welding, if there is a molten pool, it must be filled with spot welding (commonly known as Baotou and Bao Jiao) 6. If climbing arc welding requires a small welding angle, it can be picked up directly without swinging, and the technical requirements are a bit high. 7. The above is a personal summary of high-quality vertical welding. If the requirements are low, you can go back, but I want to say,' people with low skills may think that the requirements of that method are not high, but I said that when you go back, you can only see one person's welding skills.
