– obtaining one – piece compounds by establishing interatomic bonds between the joined parts when they are heated and (or) plastic deformation.
– the technological process of connecting the metal (s) with such heating and / or pressure, as a result of which the continuity of the structure of the connected metal (s) is obtained.
Can be used or not used filler metal , the melting point of which is of the same order as that of the base metal (s); the result of welding is a welded joint .
This definition also includes surfacing .
By the term: fusion welding ; pressure welding ; welded construction .
METAL WELDING CLASSIFICATION
“Welding of metals. Classification” , welding of metals are classified according to three main characteristics :
Types of fusion welding using thermal energy:
- Electron beam
- Plasma beam
- Ion beam
- Glow discharge
Types of welding, carried out using heat energy and pressure :
- Induction press
- Gas press
- Arc press
- Slag pressing
Types of welding, carried out using mechanical energy and pressure:
- Magnetic pulse
