Laser beam soldering of aluminium alloys

摘要

Laser beam soldering aluminum alloys comprises coating the joining sites with an agent absorbing laser energy. Preferred Features: The agent absorbing laser energy is a fluxing agent, fluxing agent paste or a fluxing agent metal powder. The fluxing agent is cesium fluoro aluminate, potassium fluoro aluminate or their mixtures with Al/Si, Al/Zn or Si powder; or K2SiF6, KZnF or CsSiF.
