摘　　要：以非电量电测量法测定铸钢焊接件的残余应力值,为工程实际提供残余应力指标。通过在铸钢焊接件上粘贴电阻应变片,采用钻孔法在试件上钻孔使应变释放,通过电阻应变仪测量应变值,以弹性理论计算出残余应力值,并对实验结果进行分析讨论。Test the residual stress values of the welding pieces of cast steel using the method of Non-electric power measurement. Provide residual stress indicators for the engineering. Paste the strain gauges on welding pieces of cast steel , Drilling on the the sample by the method of drilling to release the contingency. Test strain value through strain resistance measurement, and calcu- late the value of the residual stress using elasticity theory. Analyze and discuss the experimental results.
