  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. Weldability - Wikipedia

    en.wikipedia.org/wiki/Weldability

    Many metals and thermoplastics can be welded, but some are easier to weld than others (see Rheological weldability). A material's weldability is used to determine the welding process and to compare the final weld quality to other materials. Weldability is often hard to define quantitatively, so most standards define it qualitatively.

  4. Fatigue of welded joints - Wikipedia

    en.wikipedia.org/wiki/Fatigue_of_Welded_Joints

    During the welding process, residual stresses can present themselves in the area of the weld, either in the heat affected zone or fusion zone. The mean stress a welded joint may see in application, can be altered due to the welding processes implementing residual stresses, changing the fatigue life and can render S-N laboratory testing results.

  5. 6061 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/6061_aluminium_alloy

    Typically, after welding, the properties near the weld are those of 6061-T4, a loss of strength of around 40%. The material can be re-heat-treated to restore near -T6 temper for the whole piece. After welding, the material can naturally age and restore some of its strength as well.

  6. Welding - Wikipedia

    en.wikipedia.org/wiki/Welding

    Overhead stick welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion.

  7. Aluminium–copper alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–copper_alloys

    Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements.Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu(Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).

  9. Electron-beam welding - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_welding

    Welding speed – The welding equipment enables adjustment of the relative speed of motion of the workpiece with respect to the beam in wide enough limits, e.g., between 2 and 50 mm/s. Material properties – Depending on conditions, the extent of evaporation may vary, from negligible to complete.
