Working principle and characteristics of Electron Beam Welding of Copper Manganin Shunt of magnetic latching relay
The working principle of electron beam welding is: under vacuum conditions, the electron beam emitted from the electron gun is accelerated by a high voltage (usually 20-300kV), and is focused into an electron beam with high energy density through an electromagnetic lens. When the electron beam bombards the workpiece Energy Meter Shunts, the kinetic energy of the electrons is converted into heat energy, and the local temperature of the welding zone can rise sharply to more than 6000 ℃. The workpiece material of Copper Manganin Shunt is partially melted to achieve welding.
①High heating power density
The power of the electron beam is the product Electricity Meter Shunt of the beam current and its accelerating voltage, and the power of the electron beam can range from tens of kW to more than 100 kW. The power of the electron beam spot (or focus) can reach 106-108W/cm2, which is about 100-1000 times higher than the arc power density. Due to the high power density, concentrated heating, high thermal efficiency, and small heat input required to form the same weld joint, the electron beam is suitable for the welding of refractory metals and metal materials with strong thermal sensitivity. Moreover, the deformation after welding is small, and the finished parts Manganin Shunt Resistor for Current Measurement can be welded.
②The welding seam penetration and penetration ratio (that is, the aspect ratio) is large
The penetration-width ratio of ordinary arc welding is difficult to exceed 2. The ratio of electron beam welding can be as high as 20 or more, so electron beam welding can use high-power electron beams to perform single-sided welding of large-thickness steel plates without grooves. Thus greatly improving the technical and economic indicators of thick plate welding. At present, the maximum thickness of steel plates Customizable Copper Manganin Shunt Resistor for electron beam single-sided welding exceeds 100 mm, while the maximum thickness of electron beam welding for aluminum alloys has exceeded 300 mm.
③The atmosphere around the molten pool is of high purity
Because electron beam welding is carried out in a vacuum environment with a vacuum degree of 10-2 to 10-4Pa. The amount of oxygen and nitrogen present in the residual gas is hundreds of times less than that of 99.99% pure argon gas, so electron beam welding does not have the problem of oxidation pollution of weld metal Shunt Assembly. Therefore, it is especially suitable for welding metals with strong chemical activity, high purity and easy to be polluted by the atmosphere (oxidation) at the melting temperature. Such as aluminum, titanium, zirconium, molybdenum, high-strength steel, high-alloy steel and stainless steel. This welding method is also suitable for high melting point metals and can be used for tungsten-tungsten welding.
The structure of the Magnetic Latching Relay
The magnetic latching relay is divided into two layers, the upper layer is the electromagnetic system, and the lower layer is the Silver Electric Contact system. The electromagnetic system adopts a flat direct-acting magnetic latching magnetic circuit system, which includes a Terminal Block Manganin Shunt, a coil, an Electrician pure iron armature, an Electrician pure iron core, and a mounting plate. The Prepayment Meter Shunts are located on the mounting plate. In the center, coils are installed on both sides of the Cable Wire Shunt Resistor, a U-shaped iron core is arranged above the coil, and the armature is positioned between the iron cores to form an annular structure, which can be controlled by a Primary Wire Manganin Shunt field. Both ends of the mounting plate are located beside the U-shaped bottom of the iron core, and a pure iron plate is also installed to prevent the interference of external Braze Welding Shunt Resistance fields (for Energy Meter ).
