Dip Brazing
Ben Machine is a leader in dip brazing services for the military aerospace industry, earning this role thanks to the development of unique expertise in engineering, designing, manufacturing and assembling complex aerospace enclosures.
Welding complex aluminum structures can require numerous fixtures and complex sequences of parts that are inherently costly. Missing a step or variation in the welding or fixturing can result in a scrap part. Even when done correctly, the distortion coming from the welding process can make high precision requirements impossible to achieve.
Dip brazing offers a method to simultaneously fuse all the joints in a component. It is an excellent solution for complex configurations where there are inaccessible sections within the enclosure that require high precision.
The Process
Dip brazing is a process that allows simultaneous joining of multiple joints with different material thicknesses. An assembly first gets flux applied.
This keeps the filler metal in place while being immersed in the brazing salt bath. The form of filler alloy varies to suit the type of joint. As the filler metal starts melting, the flux dissolves into the salt bath. The alloy filler metal runs into the joint spaces, permanently bonding the pieces.
By quickly and evenly heating all of the components, the precision between parts is superior to welding.
Benefits of Dip Brazing
Material Savings. Unlike castings or machined parts, dip brazing can be done at near net size.
Low tooling cost. The dip brazing process uses little to no special tooling equipment. Using common fixtures allows Ben Machine to further lower tooling costs and set up times.
Less chance of product distortion. Dip brazing heats metals uniformly allowing for less risk of distortion compared to welding.
Uniform and timely. Because all joints of a component can be brazed simultaneously, the process produces components quickly and evenly.
Improved Structural Integrity. Dip brazing offers a continuous leak-tight and EMI shielded joint even with a variety of material thicknesses.
Better Conductivity. As the dip brazed joint is aluminum, conductivity is clearly better than that achieved with an adhesive bonded or mechanically attached assembly.
Design Freedom. The design engineer will enjoy a greater range of options using the dip brazed process.
