A REVIEW PAPER ON LASER WELD PARAMETER FEA ANALYSIS

In this paper we are going to analyze the BIW (Body In White) using ANSYS software .The BIW consist mainly two part i.e. top hat and flat plate which are joint together by using laser spot weld. Spot welds made by resistance spot welding are used extensively in automotive engineering. More recent material, equipment and welding process developments to extend electrode-life, enhance weld quality and reduce power consumption are making this process increasingly attractive to automakers [1].. In this work firstly outlines some of the existing modeling of top hat and analyzed by using ANSYS software for different static load and validate by using free hammer test. SOLID 285 (Tetrahedral 4 node 285) elements is used FE modeling. In this work, we are using LVDT accelerometer to calculate the modal frequency of the different BIW part at given static load. Also, by using ANSYS V 12.0 software we going to generate mesh BIW part and model generated by using PRO-E software.
