Numerical simulation on temperature field and residual stress field in thermite welding of pipelines
During the thermite welding of in-service oil pipelines, empirical values are often used for the dosage of aluminum powder welding flux, and the uncertainty of temperature and residual stress generated during the welding poses a serious threat to the construction of pipeline and its safe operation....
