Selectively joining bodies to bearers with laser beams involves subjecting body/bodies on bearer to high intensity pulsed laser beams in vacuum or protective gas up to lower than melting temperature

摘要

The method involves placing a body or several bodies on the surface of the bearer and subjecting the body or bodies to high intensity pulsed laser beams in a vacuum or in a protective gas up to a temperature lower than the melting temp. of the body or bodies, whereby a pulsed radiation pressure acts on the body or bodies simultaneously. The bodies can be applied in the form of a powder. Independent claims are also included for the following: (a) an arrangement for implementing the inventive method (b) and the use of an ultrashort pulse laser.
