Because of the special properties of powder metallurgy materials and manufacturing technology, it has been widely used in
some areas, gradually replaced the traditional metallurgy material. Now the most considerable is the connection between
the powder metallurgy parts and other parts. Friends who had been in communication industry all know that most of the
optical fiber base late parts after period needs welding process. Before the last century, we applied the most extensive is
the brazing and projection welding, but the combination degree is not high, can’t adapt to high temperature and high
strength occasion.
With the development of technology, at the beginning of the last century in the field of powder metallurgy welding and
cutting field, joined in a new laser welding, numerous advantages, suddenly foil the advantages of powder metallurgy. Laser welding compared with the traditional welding, has the following advantages: depth to width ratio is big, welding
line is narrow, high bonding strength, small heat affected zone, small welding deformation, effectively improve the
productivity but also to realize the automatic welding process etc.
Now science and technology so developed, every industry has a breakthrough, laser welding effectively solve the
connection between powder metallurgy parts and other parts. It is believed in the near future, powder metallurgy parts of
welding subject will enter a new breakthrough.
