E-beam welding is a process where a high energy beam of electrons from an electron gun is accelerated and focused using electric and magnetic fields, and shot at two materials to join them. The kinetic energy of the electrons creates very high heat which melts the two materials together (electrons are particles with a very small mass, 9*10-31 kg or 2*10-30 lbs to be exact). The electron beam requires that the system be under vacuum to maintain the speed and focus of the electrons thus preventing beam dissipation or scattering (without vacuum, the electrons would run into other molecules in the atmosphere like nitrogen, oxygen, and water vapor, among others). This is where Televac® vacuum gauging comes in, to make sure that the system is under sufficient vacuum to operate correctly.
E-빔 용접, AMS 2680 및 AMS 2681에 관해서 두 가지 관련 AMS 사양이 있습니다. 두 개의 다른 진공 레벨을 1*10-4 토르와 1*10-3 Torr로 각각 호출합니다. 항공 우주 사양을 위한 것입니다. 시스템의 진공 수준 과 정확도 요구 사항에 따라 다음과 같은 중요한 차이점이 있는 Televac 진공 측정을 위한 몇 가지 옵션이 있습니다.
The first option is an active gauge solution. With an active gauge, the control electronics are attached directly to the physical sensor, then there are optional outputs to show the vacuum level including an analog 0 to 10 V output, RS-485 communications, EthernetIP, or PROFINET communications. The active gauges that would be used for E-Beam welding are an MX2A or MX4A (thermocouple vacuum gauges) for measurement from 1000 Torr down to 1*10-3 Torr and then an MX7B (cold cathode vacuum gauge) for measurement from 1*10-3 Torr and deeper vacuum (as low as 1*10-8 Torr).
The second option is to separate the control electronics from the physical sensor. This can be ideal if you need or want a remote display somewhere else on your E-Beam welder. The ideal solutions for this are the MV2A and 2A sensor if you only need measurement down to 1*10-3 Torr, or the MX200 with a 2A/4A (again for rough vacuum measurement down to 1*10-3 Torr) combined with a 7B for medium and high vacuum measurement (down to as low as 1*10-7 Torr). Depending on which controller you choose (MV2A or MX200), you’ll have optional outputs of an analog 0 to 5 V signal, an analog 0 to 10 V signal, RS-232 communications, RS-485 communications, EthernetIP, or PROFINET communications.

E-빔 용접은 대기 중에도 수행할 수 있습니다. 빔이 대기 중의 다른 분자/가스를 타격하는 데 서식하기 때문에 용접은 일반적으로 더 넓으며 특정 응용 분야에는 적합하지 않을 수 있습니다.
