针对生产，模拟异种钢转轮焊接工艺，从焊接及金属热处理角度对异种钢转轮焊接残余应力进行了较全面细致的研究。通过大量的实验数据证明，异种钢转轮焊接残余应力分布规律无论是焊态，还是经580℃退火均以驼峰形式出现，本文详细介绍了其形貌特征。
Aiming at the production and simulation of dissimilar steel runner welding process, the welding residual stress of dissimilar steel runner is studied in detail from the perspective of welding and metal heat treatment. Through a large number of experimental data, it is proved that the distribution law of welding residual stress of dissimilar steel runner appears in the form of hump whether it is welded or annealed at 580 ℃.
