Detailed description of the invention
The core of the present invention is to provide the welding method between the material that a kind of welding characteristic is different, and this welding method can avoid the leakage between the material that welding characteristic is different。
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail。
Refer to the schematic diagram of a kind of concrete welding embodiment between the material that welding characteristic that Fig. 2 and Fig. 3, Fig. 2 provide for the embodiment of the present invention is different；The another kind of concrete schematic diagram welding embodiment between the material that welding characteristic that Fig. 3 provides for the embodiment of the present invention is different。
The invention provides the welding method between the material that a kind of welding characteristic is different, its core is in that, it is provided with transition segment between the material that welding characteristic is different, the welding affinity material different from multiple welding characteristics of this transition segment close, thus materials different from welding characteristic for transition segment is welded, so just materials different for welding characteristic can be attached。
It is to say, owing to transition segment is overall as one, after the material welding that therefore transition segment is different from welding characteristic, the connection between the material welding that welding characteristic is different is reliable, thus indirectly achieving the welding of the different material of welding characteristic；Adopt above-mentioned set-up mode, it is possible to realize the welding between the material that welding characteristic is different, so that the connection between the different material of welding characteristic is reliable, it is to avoid between the material that welding characteristic is different, there is the accidents such as leakage occur。
Provided herein is the body welding embodiment between two kinds of different materials of welding characteristic:
The material that welding characteristic is different is specially the first mother metal 1 and the second mother metal 2；As shown in Figure of description 2。It can be seen that at first mother metal 1 in left side and be provided with transition segment 4 between second mother metal 2 on right side, transition segment 4 and the first mother metal 1 to weld affinity close；Meanwhile, transition segment 4 and the second mother metal 2 to weld affinity also close；Therefore, the left end of transition segment 4 can weld with the first mother metal 1, the right-hand member of transition segment 4 can weld with the second mother metal 2, so, by arranging transition segment 4 between the first mother metal 1 and the second mother metal 2, enable to transition segment 4 weld with the first mother metal 1 and the second mother metal 2 respectively, thus the connection realized between the first mother metal 1 and the second mother metal 2 is reliable。
Certainly, transition segment 4 can be single material；That is, if the material of transition segment 4 can be closer to the affinity that welds of the first mother metal 1 and the second mother metal 2 simultaneously, therefore just can complete the first mother metal 1 just with the transition segment 4 of single material and be connected with the second mother metal 2；Such as: the material of the first mother metal 1 is 00Cr19Ni10, the welding that material is 20MnMo of the second mother metal 2；The material of transition segment 4 adopts H1Cr24Ni13A062), transition segment 4 is both close with the 00Cr19Ni10 affinity of the first mother metal 1, close with the 20MnMo affinity of the second mother metal 2 again。It is thereby achieved that be welded to connect, it is not necessary to maintenance, maintenance, more avoid dielectric leakage, cause security incident。
