The spraying (welding) turntables specially designed for thermal spraying and supporting welding processes mostly adopt a heavy-duty stable base and high-precision slewing bearing structure, integrate a variable-frequency stepless speed regulation system, CNC indexing and positioning device as well as high-temperature resistant and splash-proof protective components, can flexibly adjust the rotation speed and angle of workpieces, stably carry various workpieces of different sizes such as cylinder blocks, flanges and aerospace components, are compatible with multiple processes including plasma spraying, high-velocity oxy-fuel (HVOF) spraying and arc welding, accurately ensure coating uniformity and weld joint consistency, greatly improve the efficiency and quality of thermal spraying-welding hybrid processing, and meet the demand for integrated multi-process processing of workpieces in the thermal spraying industry.
