Automatic Robotic Fiber Laser Welder Machine for Every Need

What is Laser Welding Robot?

Laser welding robot is a combination of laser technology and robotics. The laser welding robot system is a 6 axis robot with high flexibility, which can complete the welding of complex workpieces, and it can adapt to the changing conditions of the workpieces. The laser system can use welding lenses, cutting lenses, scanning welding lenses and even laser cladding heads. Because of the magnetic coupling connection method, different lenses can be quickly switched to each other. Laser welding robot is also known as robotic laser welding machine, robotic laser welder, laser beam welding robot, laser beam welding is the full form of LBM, so you can also call it as LBW robot.

The welding robot is composed of three basic parts: the machine, the drive system and the control system. The machine is the base and the actuator, and some robots also have a walking mechanism. Most welding robots have 3 to 6 degrees of motion, of which the wrist usually has 1 to 3 degrees of motion. The drive system includes a power device and a transmission mechanism to make the actuator produce corresponding actions. The control system sends command signals to the drive system and actuators according to the input program, and controls them.

In order to adapt the laser beam welding robot to different purposes, the mechanical interface of an axis behind the robot is usually a connecting flange, which can be connected to different tools or end effectors. Laser beam welding robots attach welding tongs or welding (cutting) guns to the final shaft flange of industrial robots so that they can perform welding, cutting or thermal spraying.

Features & Advantages of 3D Industrial Fiber Laser Welding Robot

Robotic laser welding machine is a type of 3D industrial robot that is more commonly used nowadays. It has high welding accuracy, high speed, and narrow welding seam, which is very popular in the welding field.

As we all know, traditional welding operations are relatively harmful to the human body, including MIG (Metal Inert Gas) welding and TIG (Tungsten Inert Gas) welding. MIG welder and TIG welder are arc welding, and the quality of the laser-welded project cannot be guaranteed. Many businesses start to use high-performance laser welding robots instead of manual welding operations. The robotic laser welder has high production efficiency, high welding strength, narrow welding seam, and less deformation of the workpiece. Today, let's talk about the advantages of welding robots.

Unlike the current traditional spot welding process, laser beam welding can achieve molecular bonding between two steel plates. Generally speaking, the hardness of the welded steel plate is equivalent to a whole steel plate, thereby increasing the strength of the body by 30% and the accuracy of the body The same is greatly improved. Of course, the practical significance of laser welding does not stop there. Generally speaking, the bumps from the ground when the vehicle is traveling on the road will be converted into thousands of twisting motions per minute to test the body. If the body combination accuracy and strength are not enough, the abnormal frequency and noise in the car will be frequent, and it may be serious. This can cause damage to the parts installed on the vehicle, such as the gearbox, front and rear axles, or breakage of the body.

Laser welding is characterized by extremely small deformation of the welded workpiece, almost no connection gap, and high welding depth/width ratio, so the welding quality is higher than traditional welding methods. Through electronic computer processing, according to different welding objects and requirements, such as welding seam tracking, defect detection, welding seam quality monitoring and other projects are realized, and the welding process parameters are adjusted through feedback control to realize automatic laser welding. Therefore, laser welding is a very technologically advanced manufacturing process.

⇲ The power and size of the laser focus can be dynamically adjusted according to the processing requirements, and the processing process can be monitored in real time to achieve various application possibilities.

⇲ The beam spot is small, and the processing accuracy is doubled. The heat affected zone is extremely small, the weld quality is high, and it is not easy to produce shrinkage, deformation, embrittlement and thermal cracking and other thermal side effects. The laser welding molten pool purification effect can purify the weld metal, and the mechanical properties of the weld are equal to or better than the base metal.

⇲ The use of optical fiber to transport the laser, so that the energy source and the processing equipment can be separated from the space without difficulty. The light energy generated by the laser can be transmitted to a long distance station through a small diameter optical fiber, and the workpiece can be welded through a robot.

⇲ A robotic laser welding machine can replace 3 to 4 resistance welding robots. If you make full use of laser welding technology to process a car body, the cost of tooling investment, weldment preparation, material consumption, and body sealing will be reduced by approximately At US$200, the utilization rate of steel can be increased by 50%. The use of robotic laser beam welding machine can save a lot of prototypes and tooling equipment, so that the workshop area is halved and investment is saved.
