| Abstract: | According to the applied environment and requirements of the subsea Christmas tree, this article conducted a technical analysis on the mechanism, distribution and influencing factors of the residual stress which generated by steel construction welding on subsea Christmas tree, in addition, an elaborating of the major solving measures on controlling the welding residual stress on steel construction of subsea Christmas tree is given in this article. On this basis, the solutions have been developed and applied to the subsea Christmas tree project. The result indicated that it is capable of meeting the design requirements. |
