Embodiment approach

[0159] Vacuum or inert atmosphere are only preferred embodiments to prevent oxidation of metals, the inventors have found that sealing welding and / or pressing can be carried out entirely in atmospheric atmosphere. On the one hand, the inventors found that due to the close contact or close distance between the metal parts, the influence of oxygen is limited, and even without sealing and welding, it is still very difficult to exchange with the outside air. On the other hand, after the metal parts are sealed and welded together, the contact surface is airtightly isolated from the outside world, and there is little oxygen in the sealed space, which has little effect. According to one embodiment of the invention, the method of the invention does not comprise a vacuum step. According to one embodiment of the invention, the method of the invention does not comprise the step of replacing the air with an inert gas.

[0160] Seal welding of the edge 18 can be done in a manner known in ...

Embodiment 1

[0193] Two metal plates, industrially pure titanium TA1 and titanium alloy TC4 (Ti-6Al-4V), are used to clean the surface to remove all surface oxide layers and impurities. Such as figure 1 As shown, the two metal plates are stacked alternately. Pre-pressing is carried out on a hydraulic press so that the metal sheets are in close contact.

[0194] Using argon arc welding, the edges 18 of the contact surface between the two metal plates are hermetically welded together so that the contact surface or space between the two metal plates is airtightly isolated from the outside world to form a laminated body 10 .

[0195] The laminated body 10 was placed in a heating furnace and heated to 1650°C.

[0196] Such as Figure 2A As shown, the heated laminate 10 is high pressure pressed on a 100 ton hydraulic press with a pressure of 4 tons. After pressing, the two metal plates are forged and welded together to form a single billet.

Embodiment 2 to Embodiment 5

[0198] The same steps as in Example 1 were used, except that the metal materials listed in Table 1 were used.

Abstract

The invention provides a method for preparing a metal lamination material. The method for preparing the metal lamination material comprises the following steps: (a) a first metal piece and a second metal piece are arranged in a lamination manner, and both contain titanium; (b) the edges of contacted surfaces between the first metal piece and the second metal piece are welded together; (c) the first metal piece and the second metal piece are heated; and (d) the first metal piece and the second metal piece are pressed or forged, so that forge welding of the first metal piece and the second metalpiece is achieved. The method has the advantages of low cost, simple process, large-scale production and the like.
