Many users overlook brazing quality when evaluating TCT saw blades, yet the metallurgical bond between the steel substrate and tungsten carbide tip directly determines service life and cutting safety. At ZhenJiang RayLan Import and Export Co., Ltd., our core brazing workflow is fully automated and monitored in real time, eliminating unstable manual welding defects such as virtual welding, insufficient solder or overheating burn loss.
We select matched silver-copper brazing filler metals and strictly control heating temperature and holding duration. This creates a uniform, low-stress bonding layer between carbide tips and blade body. Blades processed by this technology can withstand continuous high-speed cutting, resisting tooth chipping or tip shedding even under heavy-load cutting of engineered wood and aluminum alloy.
After brazing, every blade goes through film scanning inspection and impact testing. We reject products with tiny invisible bonding cracks. Unlike ordinary factories that only carry out sampling inspection, our 100% inspection standard ensures consistency across bulk orders.
Our technical team continuously optimizes brazing parameters for different application scenarios. For aluminum cutting blades, we adjust thermal input to reduce residual stress; for heavy wood ripping blades, we enhance joint strength to resist periodic impact. Combined with CNC tooth grinding and tension calibration, our blades maintain stable runout during long-term production.
RayLan focuses on invisible core processes. Reliable brazing means fewer unexpected downtime risks for your workshop. We support OEM and ODM customization, and can adjust brazing specifications according to your cutting equipment and raw materials.
