焊接对于当代中国管道行业起着至关重要的作用,目前压力管道广泛应用于石油化工等行业,也向规模化、多样化和复杂化的方向发展,然而如何处理具有缺陷的压力管道是目前工程界所关注的问题。文章结合计算和现有的数据,针对焊接接头出现的不同位置、不同的条件下所出现的错边问题,研究错边对压力管道焊接接头应力集中影响。
Welding plays a crucial role in the pipe industry in contemporary China. At present, the pressure pipe is widely used in the petrochemical industry, but also in the direction of large-scale, diversified and complicated. However, how to deal with the defective pressure pipe is the current project Concerns of the community. Combined with the calculation and the existing data, the paper studies the influence of wrong edge on the stress concentration of welded joints of pressure pipes according to the different wrong places appeared in different positions and different conditions of welded joints.
