[Abstract]Welding residual stress will be generated in the welding process. There are relatively few researches on the detection of welding residual stress by SmartSite RS type stress meter. The SmartSite RS type stress meter detects the residual stress of 16 MnDR welded joints under different heat input， studies the influence of welding heat input on the residual stress and guides the application of this type of equipment in actual production， which is of great significance.
