Fully Automatic Laser Welder for Diamond Blades – 30% Faster Production, 24/7 Operation
In the field of diamond saw blade manufacturing, traditional welding methods (such as high-frequency welding) are gradually unable to meet the demands of large-scale production in terms of efficiency, thermal impact, and automation. To address this, a new fully automatic laser welding machine – the Automatic Laser Welding Machine for Diamond Saw Blades – combines comprehensive functions, high-precision control, continuous operation capability, and stable process performance, achieving 30% higher production efficiency and 24/7 unattended continuous operation, effectively balancing batch output with consistent quality.
This machine features complete functions, capable of welding high and low segments, helical segments, and AB segments, adapting to different blade designs. The automatic welding centering function is preset before shipment, ensuring high side clearance accuracy without on-site adjustments. A high-precision indexing plate automatically indexes according to the preset number of teeth, ensuring consistent and accurate welding positions for each segment. The user-friendly interface allows one‑click recall of common specifications, reducing setup time.
From automatic loading and unloading of the blade body to automatic feeding of the segments, the entire process is fully automated. Operators only need to perform initial setup and monitoring, and the machine continuously executes welding tasks, significantly reducing manual intervention – providing the foundation for 24/7 continuous operation. With optimized servo and control response, welding speed is increased by approximately 30% compared to traditional systems, meeting the cycle time requirements of mass production. Additionally, the machine features fault self-diagnosis and alarm indication, helping to quickly resolve abnormalities and reduce downtime.
Compared with high-frequency welding, laser welding features highly concentrated energy. This machine uses a 3.0kW IPG fiber laser generator (laser source origin: China), with welding power generally set below 1700W. It completes single‑point welding within milliseconds, producing a very narrow heat‑affected zone, thereby achieving:
- Minimal thermal damage – effectively protecting diamond particles from performance degradation due to high temperatures
- Beautiful and consistent weld seam – no spatter or burn‑through
- Segment not easy to fall off or deform – maintaining high bond strength even under prolonged cutting conditions
- No post‑weld correction required – improving overall processing efficiency
The machine uses high-quality brand components. Total power is 5500W, power supply requirement: 380V/50Hz. Welding diameter range: 90–1200 mm, blade body thickness range: 1.2–6 mm. Segment dimensions:
• Length: 20–40 mm
• Thickness: 1.5–8 mm (8–10 mm customizable)
• Height: 8–20 mm
The machine adopts CNC + PLC control with parametric programming. Welding parameters can be quickly recalled.
