Preparation of Aluminium Foam Edges for Welding

This paper presents the results of cutting aluminum foams. The experiment includes the following mechanical methods of cutting: circular saw cutting, band-saw cutting, EDM cutting, water-jet cutting, and thermal cutting methods: laser cutting and air plasma cutting. The influence of the cutting method on the edge geometry was specified in the paper. EDM was defined as the most advantageous method of Al foam cutting, as providing the best aluminium foam edges surface quality for welding.
