In submerged arc welding straight seam welded steel pipe beveling process, the general use LSAW unit, LSAW pipe mill uses advanced milling technology of floating plate plate edge processing. Plate under the action of the automatic alignment device processing center line, and then in the submerged arc welding straight seam welded steel pipe beveling process, the general use LSAW unit, LSAW pipe mill using advanced milling processes floating plate plate edge processing.

SAW straight seam welded steel pipe beveling process

Plate under the action of the automatic alignment device processing center line, then pulled by a gripping means uniform feed milling device mounted on both sides of the swing axis, guided by the floating-tracking device to follow the edge of the floating plate. When the plate edges appear wavy or bent when, under the action of the float, milling Milling operations can be performed while maintaining the relative position of the edge of the plate under the same conditions, to ensure longitudinal submerged arc welding straight seam steel pipe welding groove uniformity.
