General Welding Consumables · Welding Consumables
Regular maintenance and timely replacement of critical components are essential to ensuring the long-term reliability and optimal performance of your radar system. Hyundai Welding Co., Ltd. (Pohang) offers the SA-9NiT / S-Ni3 model, a robust navigation radar designed for X-Band and S-Band operations, meeting IMO SOLAS requirements. This electromagnetic radar is known for its durability but can encounter common issues over time. For instance, magnetron models may experience end-of-life after 5,000 to 8,000 operating hours, necessitating a spare magnetron on board with a lead time of 1-3 weeks. Additionally, the antenna's rotational motor bearings can wear out after 30,000+ hours, and issues like display backlight failure, heading marker misalignment, and waveguide moisture ingress due to compromised pressurization can arise. To maintain peak performance, it is recommended to replace the magnetron every 5,000-8,000 hours. Annual lubrication of the antenna bearings and a weekly performance monitor test, as required by IMO, are crucial for continuous operation. An annual inspection should also be scheduled to address any emerging issues before they become critical. By following these maintenance guidelines, you can ensure that your SA-9NiT / S-Ni3 radar remains a reliable and efficient tool for navigation.

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
Welding consumable batch records and welder/procedure qualifications are checked by class surveyors during hull or tank repair work involving 9% Ni or nickel-alloy joints; consumable certificates (matching heat/batch numbers) must be presented and traceable to the approved WPS for any class-witnessed repair.
