Laser welding is now people have all kinds of welding technology in good welding method, compared with the traditional welding, laser welding of advantages: small thermal deformation, welding of high precision, low noise, no pollution, easy to realize automatic welding, still can make composite welding.
Although the initial investment is larger, but processing cost is 50% less than mechanical processing.
Laser welding have advantages which can not replace the traditional welding.
Continuous or pulse laser welding with high-energy laser beams to implement, divided into heat conduction type deep penetration welding and laser welding.
Heat conduction type welding: laser radiation heating processing surface, surface heat to the internal diffusion through heat conduction, by controlling the laser power, pulse, energy density, such as laser parameters, melt artifacts, to form specific molten pool.
Melt depth of welding speed is slow.
Deep penetration laser welding: under the enough high power density laser irradiation, the material produce evaporation and the formation of small holes through them.
This hole is like a black body full of steam and absorbs almost all the energy of the incident laser beam, hole equilibrium temperature of 25000 ℃ or so, the outer wall of heat from the hot hole cavity passed out, surrounded by this hole the metal melt around the cavity.
And around the hole wall of the molten metal as the leading light speed forward, left after you remove the molten metal filling the hole and then condensing the gap, so the weld formation.
Common are in deep penetration laser welding.
The comparison of two kinds of welding methods as follows: compared with the traditional laser welding, welding head with oscillating function can improve the quality of welding, bead welding parts are not prone to vent.
Conventional welding method of welding material (
If due to the thermal cracking)
When using swing welding head has better welding quality, greatly improve the uniformity of weld.
According to the geometry and material composition of the parts, the motion of the welding head can be designed into different patterns (
Vibration welding trajectory can be set straight, O, S)
Oscillation amplitude and frequency can be modified.
Laser welding a large number of applications in sheet metal manufacturing, large heat exchanger components, hull, oil pipelines and other plate welding, gear or gear, auto parts, welding (
Airbag gas generator, illustrates, etc. )
, vehicle assembly, car doors, car seat and so on welding, cabinet, cabinet and so on industry.
Laser welding material is wide, such as: steel, copper, aluminum, titanium and other metals and alloys can realize welding, and can achieve the same material or different kinds of welding materials.
