| Abstract [eng] |
This project analyses the formation of bends occurring during the welding in fabrication industries. The bend correction process of large and small scale industries is compared and the problems due to the un-controlled bends in the erection site are to be analysed. The experimental beam is taken into analysis from the fabrication company. The beam is modelled in Solid works and undergoes analysis using ANSYS. The stress analysis is compared between the different weld bevel groove dimensions and full penetration welding process is proposed as the best solution to pursue the improvement of the material preparation. Aiming to improve the welding process different weld layers of the experimental beam is analysed. It is proposed to use different type supports of the beam during the welding process. Different type of supports are analysed under the same loads. The resulting stress and deformation is compared for different type beams. The time needed to finish the entire process in build up the beams is compared between the large scale and small scale fabrication industries. The area of maximum stress is analysed and preventive means to be used prior to welding are proposed. Aiming to define the area of maximal deformation under particular loads the deformation analysis is carried out. The conclusions of the project analysis are given. |
