Abstract

The invention discloses a system and a method applied to automatic brazing of stellite alloy long blades, relates to a system and a method applied to automatic brazing of stellite alloy long blades and aims to solve the defects that manual high-frequency brazing manner is used for operating in the prior art, the brazing operation is limited by the skills of the welders, the brazing qualification rate is low and each blade is low in consistency of brazing quality. The system applied to automatic brazing of the stellite alloy long blades comprises an IGBT high-frequency induction heating power supply device (1), a PLC control system (2), an infrared thermometer (3), an inductor with blade profile, a rigid inductor bracket (5), a four-axis transformer lifting and rotating platform (6), a blade anti-deformation supporting tool (7) and brazing operation platform tool (8). The system and the method are applied to the field of automatic brazing of the stellite alloy long blades.

Description

technical field [0001] The invention relates to an automatic high-frequency brazing system and method for Stellite alloy long blades. Background technique [0002] The long blades of the last stage of the steam turbine adopt the method of high-frequency brazing of Stellite alloy sheets on the steam inlet side to prevent water erosion. The existing technology is to operate by manual high-frequency brazing. The qualified rate of welding is low, and the consistency of the brazing quality of each blade is not good. In order to get rid of the limitations of human factors and significantly improve the quality of brazing, it is necessary to use automatic high-frequency brazing for brazing. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing technology is operated by manual high-frequency brazing, the brazing operation is limited by the skills of the welder, the qualified rate of brazing is low, and the consistency of ...
