Working with hydraulic hard lines - brazing

[crash325]

BTW... brazing does not mean "brass". It's a thermal joining process where a molten filler material is used to join metal parts through capilary action.

Soldering and Brazing
Thermal joining processes in which the molten filler metal is drawn into a capillary gap between two closely fitting surfaces. By definition:- Soldering takes place at temperatures below 450˚C and brazing above 450˚C. Both processes occur below the melting point of the metals being joined.

Silver Brazing
Is a type of brazing using filler metals containing silver that melt between 600˚C and 900˚C. Silver soldering/Hard soldering are terms synonymous with Silver Brazing (not soldering).

Fusion Welding
A thermal joining process in which the mating faces are softened or made liquid by the application of heat or pressure or by both. Filler metal with a similar composition to the parent metal may or may not be added.

Braze or Bronze Welding
A thermal joining process using a hand torch and filler metal with a lower melting point than the parent metals. The process uses copper based filler metals melting above 850˚C and does not rely on capillary attraction.

Sure nice to learn all of this. After spending a little over 30 years, Silver Soldering (up to 1250 degrees.) Gold soldering or welding up to around 1350 degrees, Platinum at a little over 3,000 degrees.

Strange that silver is named solder, brass is named brazing rod. Gold named gold solder, & platinum named solder.

the small packet left in my tool box just earned it's own spot in my garage!! WOW

We also use it for MED gas work.
