Description

technical field [0001] The invention relates to the technical field of brazing, in particular to a nickel-based solder ring and a preparation method thereof. Background technique [0002] Stainless steel has good high temperature performance and corrosion resistance, and is widely used in the manufacture of stainless steel heat exchanger piping. Brazing is a key link in the manufacture of stainless steel heat exchanger piping, which determines the service life of the heat exchanger. Due to the higher requirements for high temperature performance, nickel-based brazing filler metals are generally used to braze stainless steel pipelines. [0003] For automatic welding, nickel-based filler metals pressed into rings are the best choice for brazing stainless steel piping. However, conventionally pressed nickel-based solder rings are hard and brittle, and are easy to break and fall off during transportation or use. Contents of the invention [0004] In view of the above proble...
