Metal Welding Laser Solutions:

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.

Main Advantages of Laser Welding:

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.

Precision Laser Welding Machine GHJ-300GX

This machine adopts 1064nm pulse laser as light source. It utilizes laser radiation to heat the surface of workpiece. The surface heat transmits to the internal part of the workpiece by heat conduction effect. The width, energy, peak power and repetition frequency parameters of the laser pulse can be controlled to melt the workpiece and then form melt pool. Because of its unique advantages, this technology has been successfully applied into micro & small metal parts precision welding and welding thin metal sheet.

Laser Beam is transmitted through flexible optical fiber and then is projected on the weld joint through the welding head.

Laser welding is a non-contact welding process, no need of pressure infusion. Just required inert gas to prevent the melt pool from being oxidized.
