Abstract
This article lists the bogie manufacturing welding deformation types and damage,introduces the welding deformation correction methods commonly used,mechanical correction method and flame correction method. The paper focuses on the mechanical correction method to determine the deformation types,deformation rate calculation,determine the correct amount,as well as equipment and tool use,the fulcrum and the pressure points such factors as the selection effect on the mechanical correction.And the components placed,heating location selection,the choice of heating method,heating temperature and heating the choice of size and other factors result in increasing the critical role of flame correction.Pointed out through the analysis,the flame correction,should pay attention to the heating temperature,heating position and correct number of choice,the mechanical correction,from the amount of deformity to the strain rate again to the correction quantity's determination,should be combined with actual production,when forms the empirical formula to the specific product,the mechanical correction and the flame correction coordination use,should the overall evaluation various factors selection.关键词
