Jan 01, 2020 High-brilliance lasers allow fast, low-heat deep penetration laser welding to produce narrow seams even in metal foils. In micro-joining, adjusting comparatively small gaps is a major challenge. Here, the welding of 100 µm thick aluminum foils in lap joints is investigated. Gaps of > 80% of the foil thickness were bridged.
作者: Peer Woizeschke, Frank VollertsenFeb 19, 2016 Laser Welding Aluminum Aluminum can be a difficult material to weld. Oxidation issues can lead to contamination and porosity problems. However, cleaned correctly and handled correctly, aluminum welds well with a laser. The Challenges of Welding Aluminum Aluminum has certain properties which make it more challenging to weld than other metals.
