Abstract
Prototype of an integrated plasmatron for microplasma, laser and laser-microplasma welding of different metals up to 3 mm thick in the automatic and manual modes was designed and manufactured. Technological cababilities of this plasmatron for welding steels, titanium and aluminium alloys in the microplasma, laser and hybrid modes were studied. The efficiency of utilisation of energy of the laser beam and microplasma arc combined in a hybrid process was proved to substantially increase. Laser-microplasma welding using the microplasma arc with alternating-polarity current pulses is shown to have a high potential for joining aluminium alloys.
Keywords: electric arc, laser beam, integrated plasmatron, microplasma, laser, laser-microplasma welding, metal penetration, space, investigations
