Salt bath brazing (dip brazing) is a means of joining several pieces of metal together using an aluminium shim or wet flux between each interface joint. This is then submerged into a bath of liquid salt just hot enough to melt the shim or flux to then form a strong joint.
This rapid process still requires a series of pre-cleaning, pre-heating and quenching procedures followed by rigorous cleaning to remove any salt residue. Salt bath brazing is commonly used to create parts with different wall thickness and chambers whilst offering a lightweight but strong alternative to welding, machining and castings.
The benefits of salt bath brazing include:
# product integrity # structural flexibility # improved conductivity # reduced distortion # cost effectiveness # greater design freedom
