At present, laser welding machines are classified according to laser types, which can be divided into two types: optical fiber and YAG. So what is the difference between these two? Below, Foshan Fulan Laser will briefly talk about their differences.

1. Differences:

1. The fiber laser welding machine is composed of two parts: a cabinet and a chiller. YAG laser welding machine is composed of three parts: cabinet, power supply cabinet and chiller.

2. Optical fiber belongs to deep penetration welding (also called small hole welding); according to the nature and form of light, it can be divided into: hard optical path and soft optical path; according to the laser output energy mode: continuous laser welding. YAG welding machine belongs to heat conduction welding; according to the nature and form of light, it can be divided into hard light path and soft light path (Note: The optical fiber transmission laser welding machine changes the hard light path into soft light path through an optical fiber, so the transmission mode is changed from hard light path to soft light path. The soft optical path); according to the laser output energy mode: pulse laser welding.

3. Post-maintenance: There is no need for consumables in the later stage of the optical fiber, almost no maintenance, and the service life is longer than that of YAG. YAG has consumables in the later stage (lamps need to be replaced every 4 months or so), and maintenance is often required.

4. The optical fiber adopts pure fiber laser, with excellent beam quality, high photoelectric conversion rate (multiple times of YAG laser), and low energy consumption.

5. Optical fiber can weld thicker plates (above 0.5mm). YAG machine is mainly suitable for welding thin plates below 0.5mm, because it has the characteristics of high single-point energy, small welding width, small heat influence and small deformation.

6. YAG (optical fiber transmission machine) has energy feedback function to check the laser energy in real time. It can effectively solve energy fluctuations caused by changes in voltage fluctuations, xenon lamp discharge differences, xenon lamp aging, water flow, water temperature and other factors (energy feedback and current feedback are optional).

2. Similarities or similarities:

1. Each laser welding machine will be equipped with a chiller: it is recommended to use pure water. If the equipment is not used for a long time, you can replace a filter element in about four or five months;

2. The welding seam is fine, the precision is high, the welding speed is fast, the welding seam is firm, and the welding place is smooth and flat;

3. Weldable graphics include: point, line, circle, square or any plane graphics drawn by AUTOCAD software (self-programmable);

4. Equipped with CCD camera monitoring system, which can observe the welding seam effect and welding position in real time;

5. The equipment has high reliability and can process continuously and stably for 24 hours, and the operation and maintenance cost is low;

6. Simple operation, no need for professional welder technicians to operate;

7. It can meet welding requirements such as spot welding, tailor welding, stitch welding, and sealing welding.

Most of the laser welding machines produced by Foshan Fulan Laser Technology Co., Ltd. are custom-made (that is, non-standard machines. Non-standard machines have no fixed models. All styles are based on meeting customer requirements and then make Change accordingly.). Because each customer needs to weld the product material or shape and requirements are different, so Fulan Laser is based on the actual situation of the customer to help customers design the shape and performance of the machine, customized special automatic tooling fixtures, but also Provide customers with a complete set of laser processing equipment, laser automation integration, and various automated production lines.
