Laser beam welding of aluminum alloys 来自 SPIE 喜欢 0 阅读量: 88 作者: R Xiao 摘要: Aluminum alloys are among the most important parts of advanced materials being of strategic significance. Laser beam welding is a fast growing technology that offers new opportunities in the joining of aluminum...
Here an important current process limit for laser beam welding is the thickness of the aluminium sheets. Such limitations have been reduced by the availability of multi-kilowatt lasers; however, they could not be fully eradiated. Physical properties of aluminum that cause this are the high heat ...
