The following paper displays a summary of illustrative presentation of
electron beam welding. This presentation is a part of Days of
Science, taking place regularly in ISI Brno, usually at the beginning
of November. The visitors may see…

When some devices (e.g. vacuum or cryogenics) are manufactured, the need to
weld thin-walled parts is often met. Application of electron beam for this
purpose may bring, compared with micro-plasma or laser) some valuable advantages
balancing its higher…

The possibility to join metal parts by fusion welding depends first of all on
their metallurgical properties. This problematic is extremely wide, therefore,
in this paper, we shall restrict our interest to only some specific questions,
more important for…

The Institute of Scientific Instruments
(ISI) of the Czechoslovac Academy of Sciences
(CSAV) was founded in 1957 as successor of so-called „Scientific
Workshop“. In 1960 the founders,…

In the past, as well as today, people looked for ways how to make use of that
what the nature offered. The knowledge how to gain, process and use metals, up
today belongs to the most important skills. Names of the first known metals,
bronze and iron, had…

The depth of penetration of electron beam into material (in solid state)
depends on more factors. The most important of them are the total power
of the beam and the power density in the cross-section of the beam (the
focusation). It also…

The kinetic energy of fast moving electrons can be utilised as a source of
heat for welding. The free electrons in vacuum can be accelerated by electric
field and formed by magnetic lens into a narrow ray carrying high energy, which
is transformed into…
