Electron beam welding method for variable-section gas turbine casing

Cross-sectional configuration of the gas turbine casing structure becomes electron beam welding method, it relates to a welding method for a gas turbine casing in order to solve the conventional gas turbine casing in a cross-sectional cylinder and the like welding method can not meet the horizontal flange barrel with variable cross-section of horizontal flange welded question, which is: a, selecting electron beam welding machine; two, cleaning; Third, the receiver and the clean bench welding fixture into the vacuum chamber, the machine tooling fitted to the magazine, the two variable cross-section and horizontal flange positioned and spot welding cylinder; Fourth, the electron beam welding. The present invention will become unequal horizontal flange of the cross-sectional thickness of the structure, multi-section welded, and by adjusting the selection of the welding guns and from the current and voltage parameters, to achieve a variable thickness ranging casing sectional structure of the horizontal flange welding; greatly improved product quality and production efficiency, the present invention is a cross-sectional structure of a gas turbine casing variable welding.
