What is a QCW laser welding machine? Where is it used?

In the field of modern industrial manufacturing, welding technology is developing rapidly. As one of the best, QCW laser welding machines are playing an increasingly important role. When many factories and enterprises cooperate with laser welding machine manufacturers, some manufacturers will recommend the use of QCW welding technology. So, what exactly is a QCW laser welding machine?

QCW is the abbreviation of Quasi-Continuous Wave. QCW laser welding machine is a device that uses quasi-continuous wave laser for welding. Unlike traditional continuous wave laser welding machines, the laser it outputs is not a continuous and stable beam, but an intermittent output in the form of pulses. During each pulse, the laser will release high energy in a short period of time, so that the welded material will melt quickly and achieve connection; the pulse interval period can also allow the material to have a certain cooling time, effectively control the heat-affected zone, and reduce thermal deformation, which makes it have unique advantages in welding technology.

Features of QCW laser welding machine:

High energy density: The laser beam energy of QCW laser welding machine is concentrated, and it can complete welding in a short time, which is particularly suitable for high-precision welding needs

Low heat-affected zone: Due to the short laser pulse time and small heat input, the heat-affected zone of the workpiece during welding is very small, which effectively avoids deformation of the workpiece or damage to the material properties.

High welding speed: The welding speed of QCW laser welding machine far exceeds that of traditional welding methods, significantly improving production efficiency.

High precision: The laser beam has good focusing performance and can achieve micron-level welding accuracy, which is suitable for welding small and complex parts.

As an advanced welding equipment, QCW laser welding machine plays an important role in electronics, medical, aerospace, automobile manufacturing and jewelry processing with its high energy density, low thermal impact and high precision. It can achieve fine welding with accurate energy control, avoid damage to surrounding tiny components, and ensure product quality and stability. In product production, such as refrigerator and air conditioner refrigeration pipe welding, QCW laser welding machine can meet strict standards with its high precision and high quality welding capabilities, and the welds are beautiful and have good sealing.

In summary, QCW laser welding machine has a wide range of critical applications in many important industries with its unique working principle and stable performance. With the continuous advancement of technology, it is believed that QCW laser welding machine will play a greater role in more fields and help industrial manufacturing move to a higher level.
