Laser Welding of Dissimilar Metals without Filler Material

技术优势: • By melting only one of the two metals being joined, the technology prevents the formation of brittle intermetallic joints that would ordinarily result from the mixing of two melted dissimilar metals.• The technology eliminates the need for a filler material when joining dissimilar metals. This obviates the need for non-biocompatible filler materials in medical devices.• The technology's use of laser irradiation enables the formation of strong, highly localized joints in spatially constrained situations without risking damage to neighboring components or materials.

技术应用: • The technology can be used create mechanically robust joints between parts composed of dissimilar metals in automotive, aerospace, and medical applications.
