本文从压力容器制造技术的观点出发,评介了本届国际焊接展览会(Weldexpo China’84)中所见到的国外压力容器制造技术进展的概况。评介内容分五个方面:热切割技术和切割机控制系统、焊接技术、焊缝自动跟踪技术、鞍形缝的焊接,鞍形孔和鞍形轮廓的切割技术以及容器和管道的焊前预热和焊后热处理技术。为广大从事压力容器制造研究工作者提供了好的资料. In this paper, from the point of view of pressure vessel manufacturing technology, the overview of foreign pressure vessel manufacturing technology seen in Weldexpo China’84 was reviewed. The review is divided into five sections: thermal and cutting machine control systems, welding technology, automatic seam tracking technology, saddle seam welding, saddle hole and saddle profile cutting techniques, and preheating of containers and pipes And post-weld heat treatment technology. For the majority of pressure vessel manufacturing research workers provided a good information.
