通过文献调查，收集有关高强度铝合金焊接冶金及其对焊接性影响的可用信息。该报告的重点是高强度铝合金的熔焊。包括常规高强度铝合金和较新产品，如粉末冶金铝合金、铝锂合金和铝基复合材料。该调查涵盖了广泛的出版物，从使用传统研究设备的出版物到使用电子显微镜和高速计算机等现代分析仪器的出版物。提出了进一步研究项目的主题建议。

A literature survey was conducted to gather the information available on the welding metallurgy of high strength aluminum alloys, and its effect on their weldability. The report focuses on fusion welding of high strength aluminum alloys. Both conventional high strength aluminum alloys and newer products, e.g., PM aluminum alloys, Al-Li alloys and Al-matrix composites are included.The survey covers a wide spectrum of publications, ranging from those using traditional equipment of study to those using more modern analytical instruments, such as electron microscopy and high speed computers.Recommendations of subjects for further research programs are presented.
