Power density is a key parameter in laser processing.Higher power density can quickly heat the surface layer to its boiling point in a few microseconds, resulting in significant evaporation.Therefore, high power density is conducive to material removal processes, such as cutting, engraving, and drilling.

In the field of industrial manufacturing, the innovation of welding technology has always been a key force to promote the improvement of production efficiency and product quality. At present, robot fiber laser welding machine, with its super performance, has quickly jumped into a powerful force in industrial welding, which is inseparable from the strong support of the three core technologies.

Robotic laser welding machine has many use scenarios in the field of industrial manufacturing, including： Automobile manufacturing: Laser welding robots can be used for welding automobile bodies and parts to achieve high-precision and high-speed welding operations and improve production efficiency.

Laser welding is a field of metal processing technology that uses lasers and is widely used in various industrial fields such as automobiles, precision equipment, electrical appliances, aerospace, and medical care. Today we will choose from many laser welding applications, especially in the field of sheet metal processing, laser welding, and introduce its basic matters.

What is laser welding? The current development of laser welding technology? What fields can laser welding technology be applied to? What is laser welding? Simply put, laser welding is to heat the surface of the workpiece with laser radiation, the surface heat diffuses to the interior through heat conduction, and then by controlling the width, energy, peak power, repetition frequency and other parameters of the laser pulse, the workpiece is melted to form a specific bath, so as to achieve welding.

There are three main differences between it and pulsed fiber laser welding machine. We all know that there are continuous lasers and pulsed lasers. In fact, from the working principle, they are all pulsed types, but the output laser pulse frequency of continuous lasers is higher, and the human eye cannot recognize it.

Note: The maintenance of the portable fiber laser welding machine must be carried out by specially trained personnel, otherwise it is easy to cause serious man-made damage. 1. In order to ensure that the laser of the portable fiber laser welding machine is always in normal working condition, after two weeks of continuous work or when it is stopped for a period of time, the components in the optical path such as the YAG rod, dielectric diaphragm and lens protection glass should be checked before starting the machine to ensure that the optical components are free of dust pollution, mildew and other abnormal phenomena. If there are any abnormal phenomena, they should be handled in time to ensure that the optical components will not be damaged under strong laser irradiation. (If the use environment of the portable fiber laser welding machine is relatively clean, the above inspection can be extended to one month or even longer).

In the past 3 months, we have received many customers' questions about the comparison between laser welding and traditional welding. Perhaps you have the same question. Is laser welding really a "more advanced" choice? Today we use 3 customer on-site cases to make a real comparison. Is it suitable for your production line?

The problem of stainless steel turning black, yellowing, and bluing after welding has always troubled many sheet metal welding industries. From kitchenware to medical equipment to elevator door panels, customers have higher and higher requirements for the consistency of weld color. Many customers often ask us: "Why does fiber laser welding also turn black? Can it really be solved?"

When we use the hand held fiber laser welding machine, we must not forget to regularly maintain the equipment, because the parts of the equipment will inevitably wear out during long-term use. Only regular maintenance can keep the equipment in the most stable working state. So what we need to understand is how to maintain the hand held fiber laser welding machine? Many people don't understand it, and you will understand it after reading the following content!
