Numerical Simulation of Temperature Field in Laser Remanufacturing

“…In the laser remanufacturing process, the laser irradiates material surface, the material absorbs the light energy and converts it into heat energy, then spreads into the surrounding medium from irradiation area, so the temperature field generates. Temperature field directly affects the shape of the molten pool and material properties [3,4], so it plays an important role in optimizing process parameters and improving the quality of remanufacturing to research temperature field of laser remanufacturing.…”

3D Laser Remanufacturing of Damaged Parts

“…The factors of wide range ,shape uncertainty, different failure forms make the damaged areas with uncertainty and complexity. In addition, laser process is complex, all these make the processing quality unstable [1][2][3] .Traditional laser repairing adjust the path of processing equipment manually, which make the size and shape of laser spot in different processing position inconsistent and eventually lead to low remanufacturing accuracy that is difficult to meet the industrial requirements. In order to improve remanufacturing quality, a binocular stereo vision system is developed, which could assist in achieving 3D reconstruction , path planning and robot programs generating.…”

Research on Powder Stream of Coaxial Powder Feeding in Laser Manufacturing Technology

“…The metal powder stream's morphology and concentration field in laser coaxial cladding determines the interaction of powder stream and laser, and thus determine the size, quality and accuracy of the laser manufacturing parts. Therefore, the study of powder stream in laser coaxial cladding, not only has important scientific value, but also has a direct role in guiding for Laser manufacturing technology and industrial applications [3][4][5] . In this paper, the metal powder stream's morphology and concentration field with various parameters have been analyzed and calculated by MATLAB software, and at different size parameters of coaxial nozzle and powder mass flow rate the powder stream's morphology have been detected by CCD camera.…”
