The phrase "X-ray welding" also has an older, unrelated usage in quality control. In this context, an X-ray welder is a tradesperson who consistently welds at such a high proficiency that they rarely introduce defects into the weld pool, and are able to recognize and correct defects in the weld pool, during
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
Welding is the joining together of materials ... usually by a fusion process. ... X. X-ray welding; Xcel-Arc
Weld monitoring methods ensure the weld's quality and correctness during welding. The term is generally applied to automated monitoring for weld-quality purposes and secondarily for process-control purposes such as vision-based robot guidance. [citation needed] Visual weld monitoring is also performed during the welding process. [citation needed]
The primary disadvantages are their very high equipment costs (though these are decreasing) and a susceptibility to thermal cracking. Developments in this area include laser-hybrid welding, which uses principles from both laser beam welding and arc welding for even better weld properties, laser cladding, and x-ray welding. [53]
X-Ray LIGA is a fabrication process in microtechnology that was developed in the early 1980s [1] by a team under the leadership of Erwin Willy Becker and Wolfgang Ehrfeld at the Institute for Nuclear Process Engineering (Institut für Kernverfahrenstechnik, IKVT) at the Karlsruhe Nuclear Research Center, since renamed to the Institute for Microstructure Technology (Institut für ...
Typically low energies are required [9] for testing of composites in order to see any detail, which restricts the radiation sources to be used to x-ray types rather than gamma sources like Ir-192 or Cobalt-60, which tend to have higher energy levels. Data may be recorded either on film or digitally, using specially developed screens for ...
Electron beams impinging on metal produce X-rays. The X-rays may be diagnostic, e.g., dental or limb images. Often in these X-ray tubes the metal is a spinning disk so that it doesn't melt; the disk is spun in vacuum via a magnetic motor. The X-rays may also be used to kill cancerous tissue. The Therac-25 machine is an infamous example of this.
