The advantages of using laser welding machine welding:

(1) The amount of heat can be reduced to the minimum, and the range of gold phase changes in the heat influence area is small, and the deformation caused by thermal conductivity is also the lowest.

(2) The welding process parameters of the 32mm thick -single welding process are qualified, which can reduce the time required for thick plate welding and even save the use of filler metal.

(3) There is no need to use the electrode, no concerns of electrode pollution or damage. And because it does not belong to the contact welding process, the consumption and deformation welding of the machine can be reduced to the minimum.

(4) Laser beams are easy to focus. They are guided by optical instruments, which can be placed in an appropriate distance from the workpiece, and can be guided between the machine or obstacles around the workpiece. Essence

(5) The workpiece can be placed in a closed space (under the control of vacuum or internal gas environment).

(6) Laser beams can focus on small areas, welded with small and similar parts.

(7) The range of welded materials is large, and various heterogeneous materials can be combined with each other.

(8) It is easy to perform high -speed welding with automation, or it can be controlled by several or computer.

(9) When welding thin or fine diameter wires, it will not be susceptible to melting like an arc welding.

(10) It is not affected by the magnetic field (arc welding and electronic beam welding are easy), which can accurately align the welded parts.

(11) Welded two metals with different physical properties (such as different resistors).

(12) No X -ray protection is required in a vacuum environment.

(13) If a perforated welding, the depth of the welding track and the width ratio can reach 10: 1.

(14) You can switch the device to send the laser beam to multiple workstations.

The disadvantages of welding with laser welding machine:

(1) The location of the weld must be very accurate, and it must be within the focus of the laser beam.

(2) When the welding parts need to be used, the final location of the weld must be ensured that the solder joints that impact the impact must be aligned with the laser beam.

(3) The maximum welding thickness is limited to the workpiece that is far more than 19mm. The production line is not suitable for using laser welding.

(4) High reflection and high -thermal materials such as aluminum, copper and alloy, welding can be changed by laser.

(5) When a laser beam welded with energy to high -energy, the plasma controller needs to be used to remove the ionized gas around the molten pond to ensure that the welded tract appears again.

(6) Energy conversion efficiency is too low, usually less than 10%.

(7) The rapid solidification of the welded tract may have the concerns of pores and brittleness.

(8) Laser welding equipment is expensive.
