摘要:
为了提升厚壁管线钢板卷的强度和韧性，将高Nb化学成分和热机械控制工艺有机结合。然而高Nb成分对管线钢现场焊接性存在一定影响，因此一些管线钢用户会限制Nb的含量。对工业化生产的高Nb厚壁（23.7 mm）螺旋埋弧焊管的现场焊接性进行了评价，开发了窄坡口机械化熔化极气体保护电弧焊（GMAW）焊接工艺，环焊缝的特征证明了这一材料对陆上管道敷设典型现场焊接工艺具有适应性。本研究介绍并讨论此研究的细节和结果。
Abstract:
In order to enhance the strength and toughness of large wall-thickness pipeline steel rolled coil, the chemical composition of high Nb and thermal mechanical control process were intergated, however the high Nb composition has a certain influence on pipeline steel field weldiability, so some pipeline steel users will limit the content of Nb. In this study, field weldability of industrially produced helical pipes made from 23.7 mm thick, high Nb containing linepipe steel was evaluated. Welding procedure development was realized for narrow-groove mechanized gas metal arc welding(GMAW). Characterization of the girth welds produced revealed the suitability of the material for typical field welding procedures for onshore pipe laying. The details and the results of the investigations were presented and discussed in the paper.
