Book excerpt: [Author's abstract] Deformations and stresses induced in plates due to high temperatures represent a major concern in various structural applications. The stringent requirement of designs and to have lower production costs, these deformations needs to be addressed. In welding process, one approach used to minimize deformation is to provide sufficient clamps where the warping will be expected to occur. This takes lot of experience to know where the required tooling is to be applied and thus increases the overall cost. Avoiding clamping during the welding process would result in obvious deformations necessitating modification of the assembly process and increasing the manufacturing time. Therefore, many industries have concluded that there is a strong need for some technique that would predict the places where the sheet metal distortion would occur and reduce or eliminate the need for redundant tooling. The purpose of this study is to examine the feasibility of predicting the location and range of deformations due high temperature differences occurring during welding process. This is done, in part, to try to do effective tool design for clamping purpose. The study was performed using PRO/Mechanica package. The actual deformations occurring on the plate were measured manually to validate the simulation. As the results show, the suggested method of analysis can be used to a considerable degree of accuracy.
