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 ...

Although various computer-aided fixture design (CAFD) systems have been developed to assist the designer during the various stages of fixture design, most of previous computer aided fixture design research has mainly concentrated on machining fixtures rather than welding fixtures. The development of complicated computer aided welding fixture design (CAWFD) system has received much less attentio...

It is well khown that welding arcs emit intense ultraviolet radiation and those who conduct welding operations or work nearby are exposed to the radiation and often suffer injuries. It is desirable to evaluate the ultraviolet radiation from the viewpoint of industrial health. But, there have been few quantitative studies of this radiation. We determined the ultraviolet effective irradiance, bas...
