Therefore, accurate prediction and reduction of welding residual stress is critical in improving the quality of welding structure.
On cooling, the martensitic transformation is described using the Koistinen–Marburger relationship [6] (1) where P is proportion of phase martensite; Ms is beginning temperature of the martensitie transformation; T is the temperature and b is parameter obtained by fitting experimental data.

An important problem of PRM-140, which needs to be solved, is the reduction of the volume of the longitudinal guide mark on the inner surface of the pipes.
Longitudinal section of the deformation zone of a longitudinal rolling mill in the Deform software package On the recommendation of the software developers and taking into account the practical data of the LRM-1 and LRM-2 pipes rolling [3-7], the pipe temperature was set at T = 1200 °C, the temperature of the rolls and the mandrel was T = 150 ° C, and the air temperature was.

Although there are no reliable experimental data of this energy, some calculations have been taken on the interfacial energy of B1(NaCl)-type inclusion with austenite and ferrite [5,6].
By employing the discrete lattice plane, nearest neighbor broken bond (DLP/NNBB) model for chemical part and misfit dislocation interaction energy for structural part calculation, assuming inclusions have the cube-cube orientation with austenite and Baker-Nutting relationship with ferrite, the (001) interfacial energy Fig. 3 Strain energy distribution around an inclusion with radius due to thermal coefficient difference with matrix with the reduction of temperature by 700℃. 4 has been given as Fig. 4.
