Silver brazing method: the brazed components need to be assembled. Allows parts coated with flux in the upright position, the flux in the water will evaporate, and the dry flux is very easy to fall off, exposing metal surfaces to oxidation. Make the connection assembly, the inserting tube sets against the stop. Assembly should be firmly supported, making the whole process of brazing operation to remain in alignment. Note: the residue of the cleaning media in the cleaning and removal process should be carefully observed. Dirty or incorrect cleaning surface brazing welded difficult to satisfactory silver brazing alloy does not flow through bonding oxide on the surface of the oil spill and exposed easily oxidized and lead to gaps and debris exclusion flux.
