1. Solving the issue of a narrow beam diameter that makes it difficult to use with the swing function. The fiber laser welding machine, which is becoming mainstream due to its higher oscillation efficiency compared to YAG laser welding machines, eliminates the disadvantage of a narrow beam diameter with the "swing function." 2. Achieving reasonable prices by leveraging the strengths of a top-class specialized manufacturer in China. The 500W class handheld fiber laser welding machine utilizes the scale advantages of being a top-class precision welding machine manufacturer in China, priced at 9.8 million yen (excluding tax, transportation costs, and local adjustment fees) in the same class. Additionally, a 200-volt AC power supply, an appropriate installation location, and an inert gas cylinder are required. ■ Achieving excellent performance and functionality that surpasses TIG welding and arc welding, useful in various fields! 1. Welding width and cross-sectional shape can be finely adjusted. 2. Easier welding of gaps between workpieces. This addresses the disadvantage of fiber laser welding, which is difficult for welding gaps. 3. Suppressing spatter (sparks that scatter during welding) and achieving stable penetration depth. We have cleared the functions and performance that were challenges for both conventional YAG welding machines and fiber laser welding machines, realizing welding functions and performance that greatly exceed those of TIG welding and arc welding.

Traditionally, it was essential to tilt the processing head to prevent reflected light from returning to the oscillator. With our "UW-S Fiber Laser Welding Machine," we have achieved stable processing unaffected by reflected light by using an oscillator equipped with technology to suppress this reflected light, allowing for direct irradiation on highly reflective materials. As a result of comparative verification of output stability, we concluded that the oscillator with reflected light suppression technology does not tend to have unstable output due to reflected light. 【Comparison Verification of Output Stability】 ■ Processing ・Seam welding ■ Conditions ・Material: Copper ・Output: 1.3kW ・Speed: 50mm/sec ・Welding: Bead-on penetration none ■ Detection Measurement ・Output monitor ・Reflected light monitor *For more details, please refer to the PDF document or feel free to contact us.

Laser welding uses an optical system to focus laser light, allowing for the melting of metal in a short time, which enables welding with minimal heat impact. When the laser light is absorbed by the metal, a hole called a keyhole is formed, and a pool of molten metal is created around it. However, as the laser output increases, the excessive heat raises the upward speed of the molten metal, leading to an increase in spatter. By performing wobbling processing, it becomes possible to weld difficult materials and dissimilar metals, which are considered challenging in laser welding. 【Features】 ■ Can suppress cracks due to rapid cooling ■ Can suppress the occurrence of blowholes ■ Improvement in welding strength *For more details, please refer to the PDF document or feel free to contact us.

One of the advantages of pulse YAG laser welding is that it allows for welding with high peak and short pulses, resulting in minimal heat impact. However, if welding is performed with excessive energy, metal spatter, known as "spatter," can occur due to the compatibility of the metals, gap precision, and material properties. If the causes of spatter generation are understood, some countermeasures can be implemented. Fundamentally, it is possible that the processing conditions are not appropriate at the time of occurrence. There are various parameters such as the type of laser welding machine, emission unit, optical system of the optical fiber, setting conditions, and shielding gas. Here are some examples of measures taken against spatter. [Examples] - Setting conditions: Optimization of peak power and pulse width - Considering changes in shape, gap precision, and type of plating on the work side - Optimization of optical system specifications - Installing air nozzles, assist gas, and air knives *For more details, please refer to the PDF materials or feel free to contact us.

UW JAPAN Co., Ltd. (Shinagawa, Tokyo) began selling the industry's first fiber laser welding machine, the UW-S series, which overcomes the weakness of fiber lasers regarding reflected light, in Japan starting April 2016. Previously, challenges arose from the need to "tilt" the machine or to set strict detection levels for reflected light to mitigate its impact on the oscillator. The new feature, "reflected light suppression technology," allows for stable laser output even when reflected light is returned to the oscillator, achieving stable processing that is unaffected by reflected light, in response to the high demand for processing materials with high reflectivity, such as copper and aluminum. The output options include single mode at 700W and multi-mode ranging from 1,000W to 4,000W across five models. The UW-S series has achieved low prices through mass production effects alongside the YAG UJ series. It has been developed into a product that we confidently recommend based on its operational track record and quality.

The YAG laser welding machine "UJ Series" is a Nd:YAG laser welding machine that adapts the specifications of the top-class UW company devices from China to the Japanese environment. It incorporates reliable Japanese electronic components for critical parts that are important for the precision of the power supply. It is noted for its waveform control function that ensures good welding quality, and it is also capable of setting a "sawtooth" waveform that is effective in reducing spatter. The heart of the optical system (YAG crystal 'YAG') uses premium-grade YAG rods made in the USA, which allows it to meet both the "basic specifications" and the stringent quality requirements of "Japanese specifications" for both optical and electrical systems. We have realized the commercialization of YAG laser welding machines with the aim of making laser welding, which has traditionally been considered "high barrier," more accessible. 【Features】 ■ Product warranty period is 2 years ■ More than 1,600 units shipped ■ Design of peripheral equipment, unit manufacturing, data measurement, and final shipping inspection are all conducted in Japan *For more details, please download the PDF.
