不同后热工艺对焊接质量的影响
发布时间：2018-08-08 21:48
【摘要】：火力发电厂金属材料易产生冷裂纹的焊口,不能立即做焊后热处理的,需要进行后热处理。不同的规程及标准对后热顺序有不同的要求。本文结合生产实际,探讨对P92钢焊口采取不同的后热处理工艺,从而判断不同的后热方式对焊口力学性能的影响。
[Abstract]:Thermal power plant metal materials are prone to cold crack welding, can not immediately do post-welding heat treatment, the need for post-heat treatment. Different procedures and standards have different requirements for the post-thermal order. In this paper, different post-heat treatment processes for the welding joint of P92 steel are discussed in order to judge the influence of different post-heat modes on the mechanical properties of the welding joint.
