Abstract

Laser Additive Manufacturing (LAM) is recognized as an advanced manufacturing technology with integration of precision forming and high-performance forming. Initially

principles and characteristics of two representative LAM technologies are introduced respectively

following which the research developments of Xi’an Jiaotong University in the field of LAM technology are emphatically introduced from the following aspects: (1) The effects of ultrasonic vibration assisted laser cladding deposition process on the as-deposited microstructures and properties of IN718; (2) Repair of directionally solidified DZ125L blades with DD4 by induction-assisted laser cladding deposition process; (3) The laser cladding deposition process of CuW functionally gradient composite materials; (4) Effects of the purity of powder carrier gas on the microstructures and properties of 40Cr repaired with Fe314 by laser cladding. Ultimately

the challenges that LAM technology may confront with are explained.
