in this paper, the optimum shape of tailor-welded blanks (twb) is investigated. the optimization is performed for two different case studies. the first example is deep drawing of a twb with dissimilar materials and uniform thicknesses and the next example is deep drawing of a twb with similar materials and non-uniform thicknesses. the effect of blank optimization on the weld line movement is in...

The present work has been carried out to study the sensitization behavior of AISI 304L austenitic stainless steel weld, fabricated using GTAW (gas tungsten arc welding process). This weld was subjected to post weld thermal aging (PWTA) treatments lying in the sensitization range, viz. 700 ?C for 30 minutes, 500 minutes and 1000 minutes for studying the influence of carbide precipitation on thei...

This paper presents dual-thread Weld architecture for VLIW/EPIC processors. The dual-thread Weld model supports one main thread and one speculative thread running simultaneously in a VLIW/EPIC processor with a register file and a fetch unit per thread. This paper analyzes the cost-performance impact of the dual-thread Weld model, which includes analysis of migrating the disambiguation hardware ...
