The Brazing Story:
In the manufacturing of its pressurized sprayers, Milwaukee Sprayer relies on the brazing process to join brass to brass and form three separate joints. Using a torch to heat, an operator brazes inlet and outlet adapters onto the top of the brass sprayer shell. Two distinct joints are made. The third joint is formed when the bottom portion of the sprayer is joined to the shell. This process is semi-automatic and occurs as the part is rotated in an automated flame brazer.
To produce the strong brazed joints, Milwaukee Sprayer uses Lucas Milhaupt’s SILVALOY® 380 and 505 special-purpose alloys, all in ring form. Prior to brazing, the parts are coated with Handy-Flux to prevent oxide formation during heating. Once the joints are formed, the parts are air cooled, quenched in hot water and cleaned. In total, the entire brazing process is completed in about 45 seconds. The finished pressurized sprayer is strong and leak-tight.
Why brazing? Brazing is the optimum choice to produce an attractive pressurized spray can. With all brass to brass connections visible to the eye, brazing’s invisible joints help ensure the very best product appearance. Along with this aesthetic benefit, the process guarantees joints that are strong and durable.
- Brazing produces virtually invisible joints for optimum appearance
- Three joints are brazed in the can assembly
- An application of flux prevents oxide formation during heating
- Using an automated flame brazer, the can bottom is joined to the shell
- The finished parts are quenched in hot water and cleaned
