Fabrication of Functionally Graded Transitions for Joining Dissimilar Alloys (Technology#: 070507-01)
Laser Engineered Net Shaping (LENS) is the tool by which graded transition joints are made from dissimilar alloys. LENS is a tool that uses a computer controlled laser system integrated with dual powder feeders. The dual powder feeders can be controlled independently so that the composition can be changed at various locations within the part for...
