Abstract
The invention discloses a liquid-phase welding method of ultrasonic auxiliary solder of molybdenum-base material. The method comprises the following steps of: clamping a molybdenum-base material weldment on a vacuum brazing furnace mounting fixture; placing the palladium-base silver copper solder on the welding surface of the molybdenum-base material weldment; then placing the molybdenum-base material weldment on a vacuum brazing furnace workpiece placing table of a vacuum brazing furnace; heating the molybdenum-base material weldment and the palladium-base silver copper solder at a temperature of 950-970 DEG C; starting an ultrasonic generator; applying an ultrasonic wave with the amplitude of 0.001-0.01mm and the frequency of 20,000-100,000Hz to the molybdenum-base material weldment through an ultrasonic vibration transfer rod and the vacuum brazing furnace workpiece placing table; stopping vibration after 1-5 minutes; carrying out heat preservation for 3-6 minutes; and cooling along with the furnace to finish the entire welding operation. According to the invention, the solder is uniformly wetted on the base material and spread at the same time, the welding performance is improved, and the method is especially suitable for welding a precise and relatively large complicated molybdenum-base component.
Description
Technical field
The present invention relates to the auxiliary scolder liquid phase welding method of a kind of molybdenum base material ultrasonic wave, be mainly used in the welding field of molybdenum base material.
Background technology
Molybdenum base material is used arriving widely of each field of social production with its at high temperature excellent mechanical performance.Yet the weldability of its difference becomes the serious hindrance of this kind material sizable application, and the welding method that molybdenum base material is commonly used at present is for adopting the vacuum brazing of palladium base solder.Have following several problem: (1) molybdenum base material surface forms oxide layer and other chemical composition permeable formations easily, influence solder wetting on mother metal and sprawls.(2) when the solder of the component ratio of the same race that adopts two or more difformity or different volumes in brazing process; Solder begins to flow at mother metal and sprawls the asynchronism(-nization) that needs, run-of-the-mill big or bulky part begin earlier to flow and sprawl at mother metal.
Summary of the invention
Technical problem to be solved by this invention is to overcome a prior art difficult problem; The object of the present invention is to provide a kind of molybdenum base material ultrasonic wave to assist scolder liquid phase welding method; It is bad to have the molybdenum base material of overcoming welding forming, improves joint microstructure, realizes the characteristics of the efficient high-quality welding of molybdenum base material.
The present invention is achieved in that molybdenum base material weldment clamping on vacuum brazing furnace clamping tool; And on the solder side of molybdenum base material weldment, place palladium base silver-copper brazing alloy, then the molybdenum base material weldment is placed on the vacuum brazing furnace workpiece placement station of vacuum brazing furnace;
Between heating molybdenum base material weldment and the palladium base silver-copper brazing alloy, heating-up temperature to 950 ℃-970 ℃, make the palladium base silver-copper brazing alloy of molybdenum base material weldment centre reach fusing point; Start supersonic generator; Transmit to do through ultrasonic vibration that with the vacuum brazing furnace workpiece placement station molybdenum base material weldment to be applied amplitude be 0.001-0.01mm, frequency is at the ultrasonic wave of 20000-100000Hz, vibrates to stop after 1-5 minute; Be incubated after 3-6 minute and cool off, promptly accomplish whole welding job with stove.
Advantage of the present invention is:
1, the ultrasonic vibration of introducing is constantly impacted the solder liquid phase to molybdenum base material welding surface oxide-film, its broken volatilization has been quickened in friction;
2, the solder for difformity or different volumes provides except that gravity and the effective vibration force the surface tension, and the solder that has shortened the component ratio of the same race of difformity or different volumes begins in the mobile lead time that needs of sprawling of mother metal;
3, under action of ultrasonic waves, improve solder greatly at mother metal wetting of surfaces spreading rate, helped the wetting of slit or fine pipeline;
4, be fit to the welding of accurate and bigger complicated molybdenum matrix component.
