焊后电加热热处理是近年开发的新技术。装置电脑温控仪后，提高了控温精度，可有效地降低焊接残余应力，改善接头组织性能，降低生产成本．适于在施工现场广泛应用，采用局部处理与整体处理相结合的方法，可解决以往对大型焊接结构难以进行消除应力处理的施工技术问题。
Electric heating after welding heat treatment is the development of new technologies in recent years. After installing the computer temperature controller, the accuracy of temperature control is improved, which can effectively reduce the welding residual stress, improve the joint performance and reduce the production cost. Suitable for a wide range of applications in the construction site, the combination of partial treatment and overall treatment can solve the construction technology problems that are difficult to eliminate stress in large-scale welded structures in the past.
