Hello old iron, this video will now talk about how to connect the first point and connect the first connection when burning the wire in the welding position.
The first molten pool has two methods, the large gap chooses to fire after the blade includes the throat large gap point front point point, quickly turn the tungsten needle to the other side, the welding wire and this side of the melt straight disconnected, and then to this side of the breach to heat up, and then point a little, the middle gap becomes smaller after the welding wire is directly connected to the middle, this is the first point method.
The second point method is when the sewing is small, the sewing is just right when it is fired from one side, and then the tungsten needle swings to the other side, the welding wire swings with the tungsten needle at the same time when swinging, and the other side of the blade pauses slightly, and then the tungsten needle is burned up, and the tube is hot, and the tungsten needle is naturally sucked up.
So many people will ask me to talk about the welding face position anchor, so these are two methods, to the brothers to demonstrate, I hope that the brothers will give a little red heart after reading this, and pay attention to support it. But the premise is that the welding position is the first point of connection, this is the same as the normal burning of the welding wire position, must choose the welding wire must be sent inside, if the edge is sent to the outside when the welding wire is not picked inside, this sticker comes to the outside, the first point of the welding wire is easy to high, so the welding wire must remember to tear from the inside, do not tear from the outside, the outside to tear the first stroke is so easy to high, I give brothers to demonstrate these two point methods.
After the fire, the foam turned the Chinese characters up, and then swinged to the other side, the foam super-transformed the Chinese characters to give up, at this time the seam is small, a wire in the middle, the steel wire has just been connected to the first point of molten after burning the molten in place, the welding wire has been given, and then this temperature is low, when the temperature comes up for a certain time, and then go back is the first method of connecting the molten pool, stop and demonstrate the second method.
The third method is the same, after the fire is thrown and burned, after the burning wire chooses to send inward, the needleless throwing to the inside swing, the welding wire provokes to this side, even on the same burning, the first point to burn the temperature up, the welding wire has been given a good temperature after reaching, this time can go up, this is the approximate two starting welding methods.
After reading it, brothers, give a little heart, pay attention to support more, thank you.
