blank seam
blank seam 双语例句
Fed a certain size strip into machine, through forming roller, steel strip became tube blank, and then used two major characteristics of high-frequency current: proximity effect and skin effect, all current flowed through tube blank interface, so that the welding power comparatively concentrated on tube blank interface, and the tube blank interface quickly heated to welding temperature, at the same time press roller extruded the pipe to make welded seam sturdy, then after cooling, sizing and straightening required specification steel pipe was finished.
