介绍大型容器现场焊后热处理的方法。通过整体热处理和局部热处理的对比试验以及有关标准的要求,认为采用局部热处理技术完全能够达到设计、工艺要求,开辟了大型容器现场焊后局部热处理的先河,填补了国内空白。
Describes the method of large post-weld heat treatment on site. Through the comparison of the overall heat treatment and local heat treatment and the requirements of relevant standards, it is considered that the local heat treatment technology can fully meet the design and process requirements, opened up a precedent for local heat treatment after welding of large vessels on site, and filled the domestic blank.
