Quasi-Continuous Wave QCW Laser Source For High Laser Power Welding

QCW Laser Source Description:

A QCW (Quasi-Continuous Wave) laser welding machine is a type of welding equipment that utilizes a pulsed laser source to perform welding operations. Unlike continuous wave lasers which emit a constant beam of light, QCW lasers emit series of short pulses with high peak power.

1.Pulsed Energy Delivery: QCW lasers deliver high-energy pulses of laser light, which allows for precise control over heat input during the welding process. This is particularly beneficial for applications that require minimal heat affected zones and reduced thermal distortion.

2.High Peak Power: The pulsed nature of QCW lasers enables them to achieve high peak power levels, which are useful for welding materials with high thermal conductivity or high reflectivity, such as copper or aluminum.

3.Increased Welding Speed: The high peak power and fast pulsing capability of QCW lasers enable faster welding speeds compared to other welding techniques. This can lead to increased productivity and reduced cycle times in industrial applications.

4.Reduced Heat Affected Zone (HAZ): The pulsed nature of QCW lasers results in shorter pulse durations and controlled heat input, leading to a smaller heat-affected zone around the weld joint. This is advantageous for welding applications where minimizing distortion and preserving material properties are critical.

5.Versatility: QCW laser welding machines can be used for a wide range of materials, including metals, alloys, plastics, and even dissimilar materials. They are commonly employed in industries such as automotive, aerospace, electronics, medical devices, and jewelry manufacturing.

6.Automation and Precision: QCW laser welding machines can be integrated into automated production lines, allowing for high precision and repeatability. They can be programmed to perform complex welding patterns and can be synchronized with other manufacturing processes.

Collimation continuous (QCW) fiber laser source is a reasonable choice for long pulse and high peak power’s industrial application. For example: spot welding, seam welding. The design is used for replacing some YAG laser source’s welding application. Get minimum maintenance cost and reduce service fee. QCW can easy to reform available most systems.

QCW Laser Source Features and Advantages:

1. Stable Laser Welding Process

The pulse welding of QCW is intermittent laser beam emission.

2. Stable molten pool.

QCW laser welding, because of its more concentrated energy and shorter action time, has a molten pool that mainly exists uniformly around the keyhole, with uniform stress and lower relative occurrence rates of pores, cracks, and splashes.

3.Smaller heat affected zone.

QCW intermittently acts on the material, giving it cooling time, making it smaller in the heat affected zone and heat input, making it more suitable for processing thin materials; And materials close to thermal sensors can only be processed using QCW laser
