What is electron beam welding?

Electron beam welding (EBW) is a fusion welding process that uses a narrow beam of high energy electrons to melt the material and create a weld that connects with two pieces of metal. Electrons-uniformly charged subatomical particles-they accelerate until 30 to 70 percent of the speed of light. At this speed, the electron beam is able to warm up the surfaces to be welded to the necessary temperature. EBW is a form of low -pressure welding that requires a high vacuum. The EBW requirements make it one of the more expensive forms of fusion welding, but the quality and depth of the weld makes it the best choice for specific situations, such as some air applications. The whole weld is made of metal pieces that are connected. The EBW beam is very narrow, allowing it to function, where minimal heating of the total material is required.

is a vacuum to form a beam in EBW. Usually a number of chambers can be used at different levels to create an EBW that can weld materiall outside the vacuum. However, low or non-linguem methods can sacrifice the purity of the weld as well as to reduce depth and increasing width.

There are a number of advantages for welding electron beams over other types of fusion welding. The greater ratio of depth to EBW width in vacuum is suitable for strong joints. The narrow run of the beam also helps to reduce the distortion of welded materials by reducing the total surface that is heated. The size of the weld can be more consistent than other types of welds, and EBW usually creates stronger than average weld.

The nature of the EBW can also make useful when combining different metals. Electron beam welding can even work to connect to reactive metals, which are easy to react when heating-and refractory metal-metal, which are heat resistant, with a melting point exceeding 3000 to 3100 ° F (approximately 1650 to 1700 ° C).

The most successful feature of EL weldingEktron beams are the cost of equipment that is much more specialized than for other fusion welding techniques. There may also be high set -up costs before determining the weld. The need to work inside the vacuum may also prove to be limiting the size of pieces that can be connected to EBW.
