specific Embodiment approach 2

[0032] Specific implementation mode two: combination Figure 3 ~ Figure 7 Describe this embodiment. The difference between this embodiment and specific embodiment 1 is: the length L of the overlapping position in step 3 of this embodiment is 1 to 5t, and the t is the wall of the high-conductivity connecting pipe 3 thick, and the gap K at the overlapping position is 0.5-3.0mm. With such arrangement, the performance of the connection joint obtained is better.

specific Embodiment approach 3

[0033] Specific implementation mode three: combination figure 1 The present embodiment is described. The difference between this embodiment and the specific embodiment 1 is that the slit gap V of the magnetic collector 2 in step 4 of this embodiment is 0.3 mm. Such an arrangement facilitates flexible use of existing coils for MPW connection, and at the same time facilitates the realization of a sealed connection at the ends of pipe fittings.

Abstract

The invention discloses a method for utilizing a magnetism collector to connect a dissimilar metal tube and relates to a method for connecting the dissimilar metal tube. The invention solves the problem existed in the existing technology that a connector with high strength and high corrosion resistance is difficult to obtain with the existing the dissimilar metal tube connecting technology, the metal at the non-connecting area is easy to deform, the cost is high, the efficiency is low and the flexibility is poor. The first method of the invention is the necking connection, the procedure thereof is: firstly installing a support device, then cleaning a connecting fitting, successively assembling the connecting fitting, the magnetism collector and a coil, and finally energizing the coil via a discharge circuit. The second method of the invention is the bulging connection, the procedure thereof is: firstly installing a support device, then cleaning a connecting fitting, successively assembling a coil, the magnetism collector and the connecting fitting, and finally energizing the coil via a discharge circuit. The connector obtained by the method of the invention has the high strength and the high corrosion resistance. The method for utilizing a magnetism collector to connect the dissimilar metal tube also has the advantages of low cost, high efficiency and good flexibility.

Description

technical field [0001] The invention relates to a method for connecting dissimilar metal pipes, belonging to the field of magnetic pulse connection of dissimilar metals. Background technique [0002] Lightweight structures and lightweight materials are the two main ways to achieve lightweight design. The lightweight, integrated and multifunctional design of the structure often requires the use of lightweight materials such as aluminum alloys and magnesium alloys to replace traditional steel, and it is also necessary to realize the connection of lightweight materials such as aluminum alloys with other metal materials. Because brittle intermetallic compounds tend to appear on the connection interface and produce a large stress gradient, it is difficult to obtain high-strength and high-corrosion-resistant connections by methods such as diffusion welding, explosive welding, rolling connection and friction welding. joints, thereby limiting the application of these lightweight ma...
