The flux also serves the purpose of cleaning any contamination left on the brazing surfaces. Flux can be applied in any number of forms including flux paste, liquid, powder or pre-made brazing pastes that combine flux with filler metal powder. Flux can also be applied using brazing rods with a coating of flux, or a flux core.
High-temperature. Brazing temperature 1870 °C. Can be used for brazing molybdenum. V 65 Nb 35: Nb 97.8 B 2.2 [5] – High-temperature. Can be used for brazing tungsten. 2.2: Nb 97.8: Nb 80 Ti 20 [5] – High-temperature. Can be used for brazing tungsten. 20: Nb 80: Pt 85 W 11 B 4 [5] – High-temperature. Joint remelt temperature 2200 °C. Can ...
Attachments can be made vertically, horizontally or even overhead. If preferred, threaded pins with nuts can be attached or cable bonded directly onto the pipe by means of a special cable lug which can be crimped on site or supplied complete as a unique integrally crimped attachment. The pin brazing unit contains all the equipment and tools ...
Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coincides with the freezing point.
Lies between soft solder and silver brazing alloys, thereby avoiding damage to critical electronics and substrate deformation and segregation. Best solder for aluminium wire to Copper busses or copper wire to aluminium busses or contacts. [69] UNS#: L91090 Sn 85 Zn 15: 199: 260 [69] Yes: No
Resistance soldering equipment, unlike conduction irons, can be used for difficult soldering and brazing applications where significantly higher temperatures may be required. This makes resistance comparable to flame soldering in some situations, but the resistance heat is more localized because of direct contact, whereas the flame might heat a ...
Solderability when using lead-free alloys can differ significantly from solderability when using lead based alloys. Noble metals may be easy to solder but they have brittle joints. The metals in the good category require a large amount of heat therefore oxidation is an issue. To overcome this a flux is required.
Ultrasound can be used for assisting tinning and soldering; an ultrasonic transducer can be mounted on the soldering iron, in a solder bath, or in the wave for wave soldering. The oxide disruption and removal involves cavitation effects between the molten solder and the base metal surface.
