Anotation:
Subject deals with modern methods of welding and soldering of metals in area of electrotechnics and electronics. There are presented technologies gas-welding, arc-welding, gas shielded welding, plasma welding, electron beam and laser welding, resistance and HF welding. A spatial attention is paid to the soldering and wire bonding in microelectronics. Practical exercises provide the basic workshop of arc welding.
Study targets:
To give students an overwiew about modern technologies of welding, soldering, wire bonding and interconnection in field of electrotechnic production.
