Laser welding robot description
This machine is fiber transmission laser welding machine , it equip the Robot Arm' stretch size is 1400mm or as customers request .This kind of laser welding machines can automatic and faster welding any shape products or complex designing welding application etc. we are not only provide the laser equipment and but also can designing the whole set of laser solution for the customers directly.
Laser welding robot advantages
Laser welding has the superiority of small welding spot diameter, narrow weld seam and excellent welding effect. After welding, there is no need further treatment or merely simple further treatment. Furthermore, laser welding is applicable to a large scale of materials and can weld various different materials. There advantages enable laser welding be widely used in varieties of precision welding processes.
1. Laser welding can control the heat input to the least demand
quantity. Its range of metallographic change in the heat-affected
zone is small. The deformation caused by the heat conduction can be
controlled to minimum.
2. Laser welding doesn’t use electrodes, so there is no electrode
contamination or electrode damage. Furthermore, because it is non -
contact welding process, equipment wear and deformation can be
reduced to minimum.
3. Laser beam is easy to focus and be aligned and is easy be guided
by optical instruments, so laser welding machines can be placed at
the appropriate distance from the workplace and laser beam can be
guided around the machine or through the obstacles. Other welding
methods are unable to take effect due to the above space
limitations.
4. The workpiece can be placed in hermetic space (under the control
of vacuum or internal gas environment.)
5. Laser beam can be focused in a small area, so laser welding can
weld small metal parts with close welding gap.
6. Laser welding is applicable to a large scale of materials and
can weld various different materials.
7. Laser welding is easy to do automatic high-speed welding and can
process under digital or computer control.
8. While welding thin metal sheets or thin wires, users will not be
disturbed by the phenomenon of melt back as arc welding.
9. Laser welding is not affected by the magnetic field (arc welding
and electron beam welding is easily to be affected) and can be
accurately focused on the welded workpiece.
10. Laser welding is applicable to metals of two different physical
properties (such as different resistance)
11. Laser welding does not need vacuum environment or X - ray
protection.
12. Laser welding can use switch devices and optical fiber to
transmit the laser beam to different work points, meeting the need
of synchronized multi-position welding and non-simultaneous multi -
position welding.
