DSAW welding principle:
Submerged arc welding uses the heat of arc welding, and manual arc welding is different: the submerged arc welding wire is exposed without paint, but it is usually seen that there is a thick layer of coating on the surface of manual arc welding, submerged arc flux It is welding that is laid out in advance, the submerged arc welding wire is extended into the flux, and the arc burns under the flux.
After the welding wire comes into contact with the workpiece and the start button is pressed, the power of the welding wire and the workpiece is instantaneous, the wire igniting car moves forward, the welding wire is continuously transported downward, and the arc is maintained to burn under the solder layer to form a molten pool. Around the arc, the flux melts to form a cavity. The cavity and molten pool continue to advance, forming a continuous molten pool and the metal solidifies. This process is carried out under traffic. Invisible to the naked eye.
Spiral steel pipe welding technology uses automatic submerged arc welding, and the welding process has high production efficiency; less production auxiliary time saves time, provides you with a pollution-free spatter welding environment, saves cleaning time, and improves welding quality. At the same time, it also ensures the necessary conditions for delivery by spiral steel pipe manufacturers, so that the production time for large orders and the double-sided submerged arc welding process are widely used in the production and welding of steel pipes.
