Laser cladding is a high-precision processing technology with high efficiency, energy saving, environmental protection and safe reliability. It needs an accurate and reliable table feed system to meet the requirement of high precision in the process of cladding. In this thesis, a preliminary study and design about the laser cladding worktable is reported. Ultrasonic vibration apparatus is introduced into the laser cladding worktable, which acts on the molten pool liquid so as to achieve grain refinement. A kind of software which can achieve automatic dynamic analysis of mechanical systems, was used to simulate the worktable's working process during laser cladding.
