Development and application of new environment-friendly flux coated filler metal ring

The background and significance of the development of the flux coated filler metal ring was briefly introduced, The selection principle of coating composition and the manufacturing technology of the coating were discussed in detail. The flux coated filler metal ring and the solid brazing electrode in environmental protection and production automation was compared. The advantages and its application fields were described. The results show that the environment-friendly flux coated filler metal ring can realize the quantitative and efficient addition of the brazing filler metal and the flux, and does not contain the organic binder, which reduces the flux consumption effectively and has the advantages such as saving environmental protection. The flux coated filler metal ring will play an important role in improving production efficiency, ensure the brazing quality of products and reducing the environment pollution, which makes the flux coated filler metal ring has a very broad application prospects.
