Influence of vibration frequency on solidification of weldments

Influence of vibration frequency on solidification of weldments

Large dendrites are fewer, and grain orientation is more randomized in the microstructure of weld beads during sub-resonant vibration welding. Hardness levels are lower in samples welded with applied vibrations than in those without. The base material used in this research was nickel alloy 690. The...

Zusammenfassung:Large dendrites are fewer, and grain orientation is more randomized in the microstructure of weld beads during sub-resonant vibration welding. Hardness levels are lower in samples welded with applied vibrations than in those without. The base material used in this research was nickel alloy 690. The weld metal was Inconel 82 wire.
