Nocolok brazing requires flux at the joining area and low-concentration flux is uniformly spreaded to products to be brazed in a chamber. However high-concentration flux needs to be applied only to a necessary spot. In general, high-concentration flux is manually applied for conventional brazing furnaces, resulting in low production efficiency and harmful environments for workers due to particles and heat etc. Therefore an economical and efficient automatic spreading system needs to be developed. In this study, an efficient automatic spreading system of high-concentration flux was successfully developed and tested with a NBF.
