Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A numerical simulation of the in-service welding on thin plates has been developed using a commercial finite element package. Full three-dimensional temperature fields for bead-on-plate welding are performed by means of the finite element analysis in heat sinking, heat input and plate thickness. The results show that the heat sinking has led to sharp drop in temperature from its peak value resulting in faster cooling. Welding cooling times (t8/5) and the maximum bottom surface temperature are found to decrease when plate thickness increases from 3 mm to 6 mm, but the values of t8/5 and the maximum bottom surface Temperature increase when heat input increase. Experimental validation of the calculation has been carried out in the laboratory. Welding experiments were carried out using welding conditions identical to those in the finite element model. The computational results are then verified by experimental observations.
