Application research on multi-pulse laser used in micro laser welding fields

The article expounded the metal how to absorb the laser's energy in detail, calculated and analysis the surface of the metal's temperate field and fuse pool, and combine the multi-pulse compose method's process that cumulate laser energy in micro laser welding applications, designed the instrument which used in the micro laser welding, then makes some theoretic and validate experiments, educed some beneficial conclusions. It has been based the next step to research the automatic and intelligent micro laser weld instrument.
