Welding is a process to join metals with different arrangements of the plates. In the shipbuilding industry, the joining of plates in such a way as to ensure higher productivity is very important, but the industry has been facing the problem of deformation for seven decades. The shipbuilding industry is trying to control this problem, but thin plates bring non-linear problems in the structure, especially in the bulkhead of the structure that leads to more deformation due to small members of the profiles. This problem occurs in the construction of yachts because clients need good outlook of the ship. To control this problem the computational analysis is the more productive method than other to solve this deformation
problem. The thermal elastic plastic FEM method is used to analyse the thermal and mechanical problems. This analysis confirmed that this TEP – Finite Element Method is applicable for the control of deformation in the thin plate.
