本文对国外不锈钢连续直缝焊管机组的发展状况作了较系统的介绍;综合评述了国外带材连续成型、焊接速度、多电极焊接、内壁气托技术、保护气体的选用、光亮热处理、内外壁焊缝的处理、在线及离线检验设备、机组自动控制及焊缝跟踪装置等工艺技术装备的特点与水平。并摘要介绍钛焊管在不锈钢焊管机组上生产时,所用成型工具与生产工艺上的不同。
In this paper, the development status of continuous stainless steel continuous welded pipe unit in foreign countries is introduced systematically. The methods of continuous forming, welding speed, multi-electrode welding, inner wall gas support technology, selection of shielding gas, bright heat treatment, Weld treatment, on-line and off-line inspection equipment, automatic control unit and weld tracking devices and other technology and equipment features and levels. And summary of titanium welded pipe in the production of stainless steel welded pipe unit, the use of molding tools and production processes are different.
