Dsaw welding
DSAW welding of principle:
Submerged arc welding is the use of arc welding heat, And manual electrode arc welding is different: submerged arc welding wire is exposed above without paint, however, what usually see manual welding electrode above is with a very thick layer coatings, submerged arc flux is previously laid be welded, submerged arc welding wire extends into the flux, the arc is burning under flux.
DSAW welding process:
Welding wire contact with the workpiece and press the start after pressing the button, the power of the moment of the wire and workpiece, wire Withdrawing ignited arc welding car to move forward, the the wire continuous downward transport, sustain the arc burning in the solder layer below the arc the formation of the weld pool. Around the arc, flux melts to form a hollow. This cavity and the pool continues to advance, to form a continuous weld puddle rear metal solidification. This process is conducted under flux. The naked eye can not see.
Spiral steel pipe welding techniques is using automatic submerged arc welding, the welding process with high production efficiency; production auxiliary less time, saving time for Rod; clean spatter free welding environment, save the time of the clean-up; weld quality. Also a necessary condition for spiral steel pipe manufacturer Delivery is guaranteed, so that the large amount of orders production time, double-sided submerged arc welding process is widely used in the production welding of steel pipe.
