The main characteristic of laser brazing is local or by using laser of high energy density, small area rapid heating to complete the soldering process.
Laser soldering is the key to the reasonable control of the laser power allocation.
Laser beams converged on the solder, solder temperature is too high to melt too fast, and the parent metal temperature insufficient solder cannot very good wetting parent metal, influence filling effect, brazing seam deformation is poor.
Laser beams converged on the parent metal, solder temperature may be too low, lead to solder or activity to reduce liquidity, parent metal melting could overheat, leads to the formation of a solder directly into molten pool fusion welding, also affect the brazing seam formation of brittle phase performance.
Laser soldering of the main process parameters are the following: 1, the laser power.
CO2 laser and YAG laser can be used in laser soldering, brazing with their respective characteristics and laser melting welding are the same.
2, the light spot diameter.
Laser brazing usually adopt defocusing spot, spot size depends on the brazing seam width.
3, brazing speed.
According to the requirement of the actual brazing, depends on the laser power, laser power is larger, the faster the brazing.
4, wire feed speed.
Size main consideration brazing seam filler wire feeding speed and good shape, and brazing wire feed speed should match, improve the brazing speed at the same time should improve the wire feeding speed.
