Embodiment 1
[0029] like Figure 1-2 Shown, a kind of electron beam welding method of producing manganin shunt comprises the following steps:
[0030] (1) Clean the surface: clean the surface of the resistance alloy assembly and the electrode assembly that make up the manganin shunt, use a sodium bicarbonate solution with a mass concentration of 10% for surface degreasing, then use hot water to clean the surface, and Dry surface moisture;
[0031] (2) Component assembly: Assemble the resistance alloy component and the electrode component according to the assembly requirements of the manganese-copper shunt, and add a layer of aluminum powder at the place where the resistance alloy component and the electrode component need to be welded. The thickness of the aluminum powder is 10 μm. After assembly The components are fixed;
[0032] (3) Vacuuming: Place the fixed components in the electron beam welding chamber, and vacuumize the electron beam welding chamber so that the vacuum degree in th...
