2. 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.

3. Dissimilar friction stir welding - Wikipedia

   en.wikipedia.org/wiki/Dissimilar_friction_stir...

   Dissimilar friction stir welding (DFSW) is the application of friction stir welding (FSW), invented in The Welding Institute (TWI) in 1991, [1] to join different base metals including aluminum, copper, steel, titanium, magnesium and other materials. [2] It is based on solid state welding that means there is no melting.

4. Exothermic welding - Wikipedia

   en.wikipedia.org/wiki/Exothermic_welding

   Exothermic welding, also known as exothermic bonding, thermite welding (TW), [1] and thermit welding, [1] is a welding process that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current.

5. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   The welding together of two tubes made from lead glass A bowl made from cast-glass. The two halves are joined together by the weld seam, running down the middle. Glasses and certain types of plastics are commonly welded materials. Unlike metals, which have a specific melting point, glasses and plastics have a melting range, called the glass ...

6. Diffusion bonding - Wikipedia

   en.wikipedia.org/wiki/Diffusion_bonding

   Diffusion bonding or diffusion welding is a solid-state welding technique used in metalworking, capable of joining similar and dissimilar metals. It operates on the principle of solid-state diffusion, wherein the atoms of two solid, metallic surfaces intersperse themselves over time.

7. Flash welding - Wikipedia

   en.wikipedia.org/wiki/Flash_welding

   Flash welding is also used in the metal building industry to increase the length of the angle iron used to fabricate joists. [1] The aluminum industry uses flash welding to join aluminum, steel, and copper in various current-carrying conductors called busbars. The steel is used for strength, the copper is used for conductivity, and the aluminum ...
