Laser Crystal
Using high-quality laser rods, it has the characteristics of high gain, low laser threshold, high laser power, beautiful welding points, high energy, and good thermal conductivity and thermal shock.
Fiber Laser Welding Machine - Automatic Laser Welder
▶ Laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts.
▶ It can realize spot welding, butt welding, stitch welding, sealing welding, etc., with small weld width, small heat-affected zone, small deformation, and welding speed Fast, smooth and beautiful welding seam, no need to handle or simple processing after welding, high welding seam quality, no air holes, precise control, small focus spot, high positioning accuracy, easy to realize automation.
▶ DF-W300 laser welding machine, with its own handheld laser welding gun, can be used as a handheld laser welding machine. A dual-use operation mode is realized.
Laser Welder Features
CCD Micro Monitor
The weiding effect is clear. Men and women all can work，high efficiency, starting up can use directly, welding speed is 5 times than the traditional technology.
Laser Power
Adopt 8 super laser power and imported IGBT bipolar transistors，to make the power supply pulse xenon lamp current more constant,high-frequency continuous welding.
Controller
Independent high-definition touch control screen，control pulse current, the setting parameters will be airomatically saved.
Laser Welder Machine For Channel Letters
The letter laser welding machine can seamlessly weld stainless steel, galvanized iron, flat steel sheet, titanium, and other metals. It can also be used for welding microelectronic parts, precision parts, digital parts, optical fiber connectors, and medical equipment.
The laser welding machine has a high degree of automation and a simple welding process. The non-contact operation method can meet the requirements of cleanliness and environmental protection. The use of a laser welding machine can achieve no noise, no pollution, no radiation, 24 hours of continuous work, which can improve the efficiency of processing parts.
Laser welding machine requires high precision of welded parts, so we can send the parts that have been processed by channel letter bending machine to laser welding machine for welding work.

FAQ
▶ The welding depth of the 200w laser welding machine is 0.5mm, which can realize spot welding and penetration welding.
▶ If you need continuous welding, you need to choose a 250w or 300w fiber laser welding machine.
▶ The greater the power of the laser welding machine, the greater the welding depth.
We will send all original documents to you by DHL after sea shipment or together with the machine by air, including Packing List, Commercial Invoice, B/L, and other certificates as required by clients.
1. Optical characteristics: spot size (laser rod diameter, fiber diameter, and type, output head parameters), focal plane height, depth of field, spot position, spot angle of incidence;
2. Control characteristics: feedback control mode, choice of power waveform.
After the fiber laser welding machine has been working continuously for two weeks or stopped for a period of time, the components in the optical path such as YAG rod, dielectric film, and lens protection glass should be checked before starting to make sure that the optical components are free from dust pollution and mildew If there are any abnormal phenomena, they should be dealt with in time to ensure that the optical components will not be damaged under strong laser irradiation. (If the use environment of the equipment is relatively clean, the equipment can be kept in normal operation for more than 1 month.)
For standard machines, it would be 7-10 days; For customized machines according to clients’ specific requirements, it would be a little longer, about 15 to 30 days.
The warranty is two years. During the warranty, in case of any problem for the machine, we will provide the parts free of charge. After the warranty, we still provide whole lifetime service.
