WEL-KEN Co., Ltd. - Exhibition Information: We will be exhibiting at the "International Welding Show 2022."

The installation of a 1KW laser oscillator enhances adaptability to aluminum materials and thick items that were difficult to weld! Switching irradiation modes according to work purposes is also possible.

The fiber laser welding machine "V-HF3000" is a handheld fiber laser welder that significantly expands its applicability through the combination of the power of a newly developed 1KW laser oscillator and our proprietary technology "Vortex Technology," which achieves high-quality welding results. ▼ What is our proprietary technology "Vortex Technology"? By swirling the laser beam, the irradiation area is enlarged, and this technology realizes a significant improvement in the weaknesses of conventional laser welders, such as "gaps in welding joints," "material precision," and "work precision." 【Features of "V-HF3000"】 ■ Equipped with a high-power 1KW oscillator ■ Capable of buildup comparable to TIG welding ■ Suitable for both medium-thickness and thin materials *If you would like welding samples, please contact us. *Visits to our showroom, on-site demonstrations, and online demonstrations are available. Please feel free to contact us if you are interested. *For more details, please refer to the PDF materials or feel free to contact us.

• Welding Machine

A lightweight ultra-compact torch that puts less strain on the operator! A collaboration between familiar TIG (welding) and VORTEX fiber laser.

The "V-HF1000" is a handheld fiber laser welding machine that fully utilizes the TIG welding technique. It is suitable for precision sheet metal work and eliminates the drawbacks of conventional laser welding. It addresses issues such as burn, scorch, distortion, and the lack of skilled workers in TIG thin material welding operations, and it forms beautiful, smooth weld beads with minimal distortion using our proprietary "Vortex Technology." ▼ What is "Vortex Technology"? By swirling the laser beam, the irradiation area is expanded, significantly improving the weaknesses of conventional laser welding machines, such as "gaps in the weld joint," "material accuracy," and "work accuracy." 【Features】 ■ Increased welding speed (more than double compared to TIG) ■ Ultra-compact torch that is lightweight and reduces the burden on the operator ■ Expanded application range for materials such as aluminum, stainless steel, and plated steel sheets ■ Ideal for thin precision sheet metal and duct fabrication *For more details, please refer to the PDF document or feel free to contact us. *If you would like welding samples, please inquire. *Visits to the showroom, on-site demonstrations, and online demonstrations are available.
