Description
Technical Field
The utility model belongs to the technical field of alloy welding, and particularly relates to a vacuum welding clamping device for refractory alloy plates.
Background
Titanium and titanium alloy have high specific strength, excellent corrosion resistance, good hot processing performance and biocompatibility, and are widely applied to the fields of aerospace, biomedicine and the like. Currently, vacuum consumable arc melting (VAR) is widely adopted for industrially produced titanium and titanium alloy ingots, and before vacuum melting, corresponding raw materials are generally selected according to component standards, and are subjected to proportioning calculation, weighing mixing, electrode block pressing, consumable electrode welding and vacuum consumable melting to obtain titanium alloy ingots.
High-melting-point elements such as Nb, mo, ta and the like are often used as constituent elements of high-performance titanium alloy materials. In view of their extremely high melting point, they are generally added as master alloys. If the intermediate alloy in the form of granular powder is added, slag falling often occurs in the vacuum consumable smelting process, high-melting-point alloy powder falling into a molten pool cannot be fully dissolved, meanwhile, the powder is easy to be lost in the electrode block preparation process, so that the chemical components of an ingot are not uniform, and defects such as local metallurgical segregation are easy to form. If the intermediate alloy scraps containing high-melting point components are added, the prepared titanium and titanium alloy cast ingots have uniform chemical components and tissues, and the risk of metallurgical defects can be reduced.
In order to obtain master alloy scraps containing high-melting point elements, it is generally required to prepare a master alloy ingot containing the high-melting point elements, and then process the ingot into scraps to be added into other high-performance titanium alloys. The preparation of the high-melting-point titanium alloy cast ingot firstly needs to prepare a consumable electrode with a certain size, and the common method is to reasonably match electrode blocks or bars or plates with a certain size, and adopt manual argon arc welding or a vacuum plasma welding box to weld the consumable electrode with a certain specification.
When the traditional titanium alloy consumable electrode is welded, manual plasma (or tungsten electrode) argon arc welding is generally adopted, titanium belongs to high-activity metal, and the titanium alloy consumable electrode can chemically react with oxygen, nitrogen and hydrogen in the air to generate brittle oxides, nitrides or hydrides. If the consumable electrode is stored for a long time under the atmospheric condition, welding spots may be cracked, and even an egg drop accident occurs in the vacuum melting process. In addition, the risk of tungsten sticking of a consumable electrode exists in manual welding, so that hard inclusion defects are easily formed in an ingot, and the quality of a product is seriously affected.
