摘要

In this study,a FE simulation model of the continuous extrusion process with double feedstocks is established.It is aimed to investigate the weld quality of AA6063 aluminium alloy profiles.The results show that with the height of preformed die increasing,the pressure-to-effective stress ratio (K) increases greatly and the welds can be improved.The maximum value of K reaches to 5.5.By observation the microstructure of the welding zone,the extrusion welding line does not extend to the product surface.No defects appeared on the surface of the extruded product.It is proved that the AA6063 product with good welding quality can be obtained by continuous extrusion with double feedstocks.These also provide the theoretical basis for expanding the application of the continuous extrusion process with double feedstocks.
