“prediction of Welding Sequence for Minimum Possible Distorsion of an Assembly like B-pillar of a Car, with Effect of Parameters on Distorsion While Welding”
نویسنده
چکیده
The aim of this paper is to achieve thespot welding sequence for minimum distortion of a sheet metal assembly and to optimise the parameters of welding which insures minimum distortion for the optimised sequence. The distortion of the assembly involving number of spot welds is different for different sequences of welding The assembly consists of sheet metal components which are joined by using various welding sequence schemes. The components are manufactured in quantity and welding with various sequences. After welding the distortions in an assembly due to welding sequence change are worked out and compaired.The temperature distribution along B-pillar is also analysed while deciding optimum sequence of welding. The sequence with minimum distortion is suggested a solution for the quality manufacturing with minimum distortion induced in it. The various parameters like weld timing or current, convection film coefficient are optimisedfor the sequence giving minimum distortion.
