2. List of brazing alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_brazing_alloys

   High-strength, low-temperature. For aluminium-to-aluminium and aluminium-to-copper. 78: 22: Ag 72 Zn 28: 710/730 [8] – Ag72Zn. Ammonia-resistant. For joining ferrous and non-ferrous metals (steel, copper, brass...). Good flow properties. With stainless steel in humid environments risk of interfacial corrosion.

3. Aluminium joining - Wikipedia

   en.wikipedia.org/wiki/Aluminium_joining

   Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.

4. Ferrocerium - Wikipedia

   en.wikipedia.org/wiki/Ferrocerium

   The idea that carbon steel is needed to produce sparks from a ferrocerium rod is an oft repeated myth, though carbon steel does make the spark more prevalent when striking. [6] Ferrocerium is most commonly used to start Bunsen burners and oxyacetylene welding torches. [citation needed] About 700 tons were produced in 2000. [citation needed]

5. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

7. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
