Firstly<\/em><\/strong>,soldadura por l\u00e1ser<\/a> is an efficient and precise welding method that uses a high energy density laser beam as a heat source.<\/p>

Laser welding<\/a> can be achieved by continuous or pulsed laser beams. The principle of laser welding can divide into heat conduction welding and laser deep welding.<\/p>

Power density less than 104~105 W\/cm2 is heat conduction welding.<\/p>

At this time, the penetration depth is shallow and the welding speed is slow;<\/p>

when the power density is greater than 105~107 W\/cm2, the metal surface is recess into \u201choles\u201d under the action of heat, forming deep penetration welding.<\/p>

Secondly<\/em><\/strong>,features of fast welding speed and large aspect ratio. Laser welding<\/a> generally uses continuous laser beams to complete the connection of materials.<\/p>

The metallurgical physical process is very similar to electron beam welding,\u00a0 the energy conversion mechanism is complete by a \u201ckey-hole\u201d structure.<\/p>

Thirdly<\/strong><\/em>,under sufficiently high power density laser irradiation, the material evaporates and forms small holes.<\/p>

This small hole filled with steam is like a black body, absorbing almost all the energy of the incident beam. The equilibrium temperature in the cavity is about 2500C.<\/p>

The heat is transfer from the outer wall of the high-temperature cavity, melting the metal surrounding the cavity.<\/p>

The small holes are fill with high-temperature steam generat by the continuous evaporation of the wall material under the beam of light.<\/p>

The four walls of the small holes surround the molten metal and the liquid metal surrounds the solid material.<\/p>

The liquid flow outside the hole wall and the surface tension of the wall layer are consistent with the steam pressure continuously generated in the hole cavity and maintain a dynamic balance.<\/p>
