| Abstract: | The weld test and heat treatment after weld were carried out by using the designed filler metals. According to the study and analysis of the tensile strength and microstructure of the as welded and heat treatment weld samples, the form of Al 3(Sc 1- x Zr x )and Al 3Sc and the effect of the addition of scandium in filler metal on 2195 aluminium lithium alloy weld were studied. The research showed that the addition of scandium in filler metal could effectively fine the particle of wold zone, improve the weld microstructure, reduce the hot crack sensitivity, and greatly enchance the weld joint strength. |
