The present invention discloses a device and method for producing flow channel components in fusion reactor cladding by explosive composite. For flow channel pipes and covering plates before molding, a certain weak acid and weak base salt powder and a certain low melting point metal particles are mixed evenly in a certain proportion and filled into the flow channel, and then the filling material is compacted with a jack until it is flush with the flow channel mouth. The compacted filling of the flow channel eliminates the huge force generated by the sudden change of wave impedance on both sides of the composite interface due to the detonation wave, ensures the integrity of the shape and microstructure of the flow channel components, and solves the problems of flow channel deformation and cracks that are common in other methods. The characteristic of weak acid and weak base salts that are easily decomposed by heat will make the filler as a whole loose when heated. At the same time, the reducing gas generated by its decomposition can protect the low melting point metal from being oxidized, ensuring that the filler can be easily and thoroughly removed when the flow channel, especially the complex special-shaped flow channel, is heated, so that there is no attachment in the resulting flow channel.
