Throat area control device and method in turbine guide vane electric welding process

Abstract

The invention provides a throat area control device and method in turbine guide vane electric welding process. Before a vane, firstly, the turbine guide vane is fixed through a dual-vane-body positioning clamp; then, the throat area on the welded turbine vane is calculated through a measuring tool for measuring before welding; and finally, by means of an area adjusting block, fine adjustment is performed on an angular direction positioning point of the vane body, and the throat area is adjusted qualified. An inductor external controller adopted by the device and method can display the area ofthe corresponding state in real time and transiently, and according to the corresponding changing, the area is controlled within a qualified range before welding and then is fixed. Due to the fact that the device is accurate in design, the requirement on experience of an operator is low. The device is successfully applied in actual welding, an original outdated welding method is replaced, and because the design concept is advanced, the device is easily popularized in turbine guide vane welding.

Description

Technical field [0001] The invention is applied to the combined welding of high-vortex guide blades, and is particularly suitable for a throat area control device and method during spot welding of turbine guide blades. Background technique [0002] In the field of aero-engines, the domestic welding of relatively complex high-pressure turbine guide blades adopts integrated fixed clamping welding. The welding process does not control the area of ​​the turbine throat that affects the important performance of aero-engines. The welding quality is restricted by the casting material, which causes the welding As a result, the turbine blade throat area is unqualified and scrapped. This technology has been solidified and applied for more than ten years and has a huge impact on the production of aero engines. In order to solve the shortcomings of the technology in practical application, it is urgent to innovate in technology and invent a method and control device to solve this problem. Sum...
