摘要:
为了确定X80管线钢焊缝横向冷裂纹敏感性影响因素,选用焊缝横向冷裂纹G-BOP(gapped bead-on-plate)试验方法,利用有限元分析计算平板焊缝应力集中部位,在模拟极端的环境温度、湿度以及预热温度的情况下,观察实际平板对接焊缝表面裂纹情况。试验结果显示,X80管线钢横向裂纹对环境湿度、温度以及预热温度不敏感。研究表明,利用这种简便、经济、实用的小型试验方法研究焊缝横向冷裂纹敏感性,对指导实际生产将起重要作用,并可为X80管线钢管环焊工艺的制定提供指导。
Abstract:
In order to determine the transverse cold crack sensitivity factors of X80 pipeline steel weld, selecting G-BOP (gapped bead-on-plate) experimental method for weld transverse cold crack, using finite element analysis to calculate the stress concentrated position of plate weld, under extreme environmental temperature, humidity and preheating temperature of the situation, the surface crack of actual plate butt weld was observed. The results showed that transverse crack of X80 pipeline steel is not sensitive to environmental temperature, humidity and preheating temperature. The research showed that using this simple, economical and practical small test method to study the weld transverse cold crack sensitivity will play an important role for guiding actual production and the establishment of X80 ring welding technology.
