Success stories: Helping enterprises improve the brazing pass rate

A large air - conditioning enterprise in Shunde has a 5 - row aluminum heat exchanger for central air conditioners. The welding pass rate has always been lower than 60% (calculated by piece), resulting in low production efficiency and unstable quality. In 2019, Xinrui Dajin received the demand from this enterprise. It organized technical personnel in aspects such as brazing equipment, flux, filler metal, and brazing process to conduct research and communication with the technical personnel of this enterprise. After multiple improvements and adjustments to the brazing equipment, flux, filler metal, and process, it successfully helped them increase the one - time welding pass rate of the commercial 5 - row aluminum heat exchanger from 90% to over 99.9% (calculated by solder joints). Calculating with 40 points for each workpiece, the welding pass rate calculated by piece increased from 60% to 96%), achieving the enterprise's technological transformation goal. In 2019, Xinrui Company became an excellent supplier of aluminum filler metal for this enterprise.
