LWFN series of laser welding machine is the application of lasers produce a wavelength of 1064nm pulsed laser through the beam expander, reflective, focused radiation processing surface, the surface of the heat through the heat transfer-based internal diffusion through digital precise control of laser pulse frequency, pulse width, energy , peak power, table speed, direction of movement and other parameters, so that the workpiece melt to form a specific pool to achieve the processing of parts by laser welding to complete the traditional precision welding process can not be achieved. Laser beam can be achieved time and energy on the splitting, both capable of processing multi-beam and multi-bit processing, providing a more precise welding conditions. Beam quality, spot fine, flexible installation, the current closed-loop control can be realized.

Features:

● welding high strength, welding speed, narrow weld and smooth surface;
● After the welding process without processing or simple process;
● weld consistency, stability;
● thermal cracking does not occur;
● weld width is small, heat-affected zone is small, does not affect the hardness of the workpiece;
● holes will not be exempt from oxidation effect;
● does not cause shrinkage deformation of the workpiece;
● Real-time closed-loop power laser energy negative feedback control;
● can repair cracks, chipping, mold side, and wear of the sealing edge;
● international brand, first-class technology, good global technical support services;

LWFN laser welding system is divided into four series, to meet the needs of different users:
● common type of laser welding machine LWFN series;
● scanning laser welding machine LWFN-S series;
● CCD positioning laser welding machine LWFN-C series;
● thermal cracking does not occur;

LWFN-S series of scanning laser welding machine
Through the galvanometer swing to achieve the fast-moving laser point can be within the scope of welding in the welding plane to achieve high-speed high-precision graphics of any welding, automatic welding machine than conventional stepper, servo motor moves the workpiece welding, welding speed has greatly improved.
Features:
§ welding and high precision, stable, easy to operate, simple to maintain;
§ workpiece in the same or different materials for different parts of the thickness of multi-condition (MAX: 32 species) high-speed spot welding;
§ ambient temperature in 20 - 35 ℃ range, the position accuracy can be controlled within ± 20um or less.

LWFN-C Series CCD laser welding machine positioning
Accurate positioning and real-time observation of the effect of welding. CCD automatic camera, identification, capture pad coordinates, real-time transmission to the PC, with the selected welding parameters; When the capture point coordinates abnormal welding, the system shut down the alarm.
Features:
§ ambient temperature of 20 - 35 degrees range, the position accuracy can be controlled within ± 15um or less;
§ CCD technology can be easily embedded into the scanning laser welding machine.

LWFN-D series of three-dimensional dynamic focus laser welding machine
The series of three-dimensional scanning galvanometer work, moving the lens and by adjusting the distance between the lens to gather the Z direction of the focal plane up and down adjustment, can solve the same parts of different heights on the workpiece welding problems.
Features:
§ Z axis dynamic focusing range of up to 200 - 400mm;
§ System Integration software controls the scanning system or bench;
§ support the workpiece rotation axis method, the workpiece can be arc welded.
