Problems solved by technology
However, the special physical and chemical properties of amorphous alloys make it difficult to weld them with common metals by conventional welding techniques
[0003] Special welding processes such as friction welding, laser welding, and pulse welding can be used for the welding of amorphous alloys and common metals, but their processes and equipment will limit the large-area composite of amorphous alloys and common metals
The explosive welding technology can also realize the welding of amorphous alloys and ordinary metals. Its biggest advantage is that it can be welded in a large area, but high temperature and high pressure will be generated during the welding process, and it is difficult to keep the physical properties of amorphous alloys unchanged.

Embodiment Construction
[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0014] (1) Processing of welding materials
[0015] Process the amorphous alloy and ordinary metal to be welded, wherein the length of the ordinary metal plate is greater than 100mm, so as to provide sufficient bombardment distance to obtain a stable detonation; the width of the ordinary metal plate (perpendicular to the sliding detonation direction) should be more than twice the length of the amorphous alloy plate to eliminate side boundary effects. Both the amorphous alloy plate and the metal plate need to be surface treated with sandpaper.
[0016] (2) Cutting board with grooves
[0017] The selection of cutting board material with grooves and the selection of geometric dimensions have a great influence on the welding results. The material of the cutting board with grooves should be selected to match the wave impedance of the amorphous all...

The invention discloses an explosive welding device for a bulk amorphous alloy and a common metal, and belongs to the technical field of welding. The device comprises a welding base plate which is a chopping block with a groove. The bulk amorphous alloy is embedded into the groove of the chopping block so as to limit deformation of the alloy during an explosive welding process. The chopping blockis made of a material having wave impedance matched with that of an amorphous alloy plate so as to prevent brittle fracture caused by bounce of the amorphous alloy plate during the explosive welding process. The length direction of the groove arranged on the chopping block is perpendicular to a sliding explosion direction so that the brittle fracture of the amorphous alloy plate is prevented during the explosive welding process. The device has advantages of keeping non-equilibrium constant and integrity of the amorphous alloy and welding the bulk amorphous alloy and the common metal together in large area.

technical field [0001] The invention relates to the welding technology of bulk amorphous alloys and common metals in the field of welding technology, in particular to an explosive welding device for bulk amorphous alloys and common metals. Background technique [0002] Amorphous alloy is a new type of material with special atomic structure, excellent physical and chemical properties, and has great potential for engineering applications. However, the special physical and chemical properties of amorphous alloys make it difficult to weld them with common metals by conventional welding techniques. [0003] Special welding processes such as friction welding, laser welding, and pulse welding can be used for welding amorphous alloys and common metals, but their techniques and equipment will limit the large-area composite of amorphous alloys and common metals. The explosive welding technology can also realize the welding of amorphous alloys and ordinary metals. Its biggest advantag...
