Working principle
By using high energy laser pulse, the material is locally heated and the energy of the laser radiation is diffused through the heat transfer guide material. It is a new welding method, laser welding mainly for thin-walled materials, precision parts welding, can achieve a spot, butt welding, lap welding, seal welding, high depth width ratio, weld width of small, small heat affected zone, small deformation, welding speed, weld smooth, beautiful, after welding, no treatment or simply processing, high quality welding seam, no pores, accurate control, small focal spot size, high positioning accuracy, easy realization of automation.
Welding characteristic
Belong to the fusion welding, the laser beam is the energy, the impact on the welding parts.
The laser beam is guided by a planar optical element, such as a mirror, and then is projected onto the weld with a reflective focusing element or lens.
Laser welding machine is a non-contact welding, process with no need of pressure, but using inert gas to prevent oxidation of molten pool, the filler metal is occasionally used.
Laser welding and MIG welding can be composed of laser MIG hybrid welding, welding, and the heat input than MIG welding is greatly reduced.
Characteristic
Mainly consists of laser, power supply and control, cooling machine, light guide and focus, binocular stereo microscope observation of a few parts, compact structure, small size. The laser beam coaxial with the laser beam of the micro coordinates, makes the workpiece positioning is easy, do not need special fixture. Laser power, pulse frequency, pulse width can be preset and changed by control panel. The power supply adopts the drawer type structure and is easy to be removed, so the operation and the maintenance of the equipment are convenient. Does not need to fill the solder, the welding speed is high, the contact is reliable, the work piece distortion is small, the shape is beautiful.
The key components, such as ceramic laser cavity using internationally renowned manufacturers of products, to ensure the high reliability and high performance of the equipment.
YAG crystal cooling of the way, improve the beam quality and xenon lamp life, reduce the use cost.
application area
The device can be welded to gold, silver, platinum, titanium and its alloys, electricity nickel belt, such as materials, for jewelry, watch hairspring, integrated circuit lead all tiny, thermal parts of precision welding, suitable for optoelectronic devices, electronics, communication, machinery, automobile, military, gold jewelry etc. industries.
