A numerical model for cold welding of metals

Wenqi Zhang, Niels Bay

    Research output: Contribution to journalJournal articlepeer-review


    Based on experimental investigations of cold welding of different metal combinations applying various surface preparation methods, the understanding of the mechanisms of bond formation in cold welding has been improved by introducing two parameters representing the properties of surface layers at the weld interface. Accordingly, the general model for bond strength in cold welding earlier developed by Bay has been extended and modified. The new model presented in this paper simulates the whole cold welding process including the deformation of base metals and the establishment of welds bonding similar as well as dissimilar metals The calculated bond strengths are verified by comparing with experimental measurements.
