Nanowelding Technology Study Based on Simulation Methods

Simulation study on nanowelding technology is important to improve nanowelding parameters, analyze the properties of welded structure, reveal the mechanism of nanowelding. In this paper, the progress of simulation study on nanowelding technology has been reviewed. The key and difficulties of this technology are proposed. The applications of molecular dynamics and quantum mechanics in nanowelding simulation study are introduced. Nanowelding technology is studied by molecular dynamics (MD) method, and the mechanism of ultrasonic nanowelding is revealed.
