Laser Welded Diamond Ring Saw Blade

Laser welding for diamond ring saw blades is a high-end, integrated welding process. It relies on a high-energy, focused fiber laser beam to precisely strike the interface between the cutting segment and the steel core, instantly melting the steel core and the segment's metal matrix locally; upon cooling, this forms a seamless, metallurgically integrated fusion layer, eliminating the need for an intermediate silver solder layer.

(At present, our diamond ring saw blades are all laser welded, abandoning the traditional high-frequency welding process)

It features the following characteristics:

1. Non-contact, automated welding with full CNC positioning, ensuring uniform and consistent weld seams;
2. An extremely narrow heat-affected zone (only 0.5–1.2 mm), where heat is localized to the weld area, preventing large-scale annealing that could damage the diamond structure within the segment;
3. Fusion strength far exceeding that of the base material, with weld tensile strength reaching up to 1800 MPa, ensuring the segments do not easily detach during continuous cutting or upon impact with thick steel reinforcement.

1 Superior Welding Strength for Enhanced Safety

• The metallurgical fusion bond creates an integrated structure; segments remain securely attached even when cutting through dense, thick rebar and hard aggregates, or during vibrations caused by jammed materials. This meets stringent European and American job-site safety standards, making it ideal for high-risk, heavy-duty projects such as bridge work and large-scale demolition.

2 High-Temperature Resistance: Versatile Dry and Wet Cutting

• Free from low-melting-point silver solder layers, the weld remains intact even during prolonged, continuous cutting that generates high heat. Segments do not detach during brief periods of dry cutting (without water cooling), making the blade reliable for sites with unstable water supplies.

3 Stable Segment Performance: Longer Lifespan and Faster Cutting

• Localized, precise heating prevents damage to the diamond crystals. The orderly arrangement (Arix technology) ensures consistent sharpness throughout the blade's life, preventing rapid dulling caused by high temperatures; under identical operating conditions, the service life exceeds that of high-frequency welded blades by over 20%.

4 Automated Mass Production: Consistent Welds and Reliable Quality Control

• Utilizing fully automated fiber laser production lines ensures uniform welding parameters for every blade, eliminating human error associated with manual welding. This guarantees stable performance across large-volume shipments; furthermore, as labor costs rise, adopting mass-production laser welding actually reduces overall manufacturing costs.
