  2. Weldability - Wikipedia

    en.wikipedia.org/wiki/Weldability

    The weldability, also known as joinability, [1] of a material refers to its ability to be welded. 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.

  4. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    In oxy-fuel welding, a welding torch is used to weld metals. Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal. The molten pool is generally supplied with additional metal called filler. Filler material selection depends upon the metals to be welded.

  5. Welding - Wikipedia

    en.wikipedia.org/wiki/Welding

    The efficiency is dependent on the welding process used, with shielded metal arc welding having a value of 0.75, gas metal arc welding and submerged arc welding, 0.9, and gas tungsten arc welding, 0.8. [64] Methods of alleviating the stresses and brittleness created in the HAZ include stress relieving and tempering. [65]

  6. Hardenability - Wikipedia

    en.wikipedia.org/wiki/Hardenability

    When a hot steel work-piece is quenched, the area in contact with the water immediately cools and its temperature equilibrates with the quenching medium.The inner depths of the material however, do not cool so rapidly, and in work-pieces that are large, the cooling rate may be slow enough to allow the austenite to transform fully into a structure other than martensite or bainite.

  7. Iron metallurgy in Africa - Wikipedia

    en.wikipedia.org/wiki/Iron_metallurgy_in_Africa

    Iron metallurgy in Africa concerns the origin and development of ferrous metallurgy on the African continent.Whereas the development of iron metallurgy in North Africa and the Horn closely mirrors that of the Ancient Near East and Mediterranean region, the three-age system is ill-suited to Sub-Saharan Africa, where copper metallurgy generally does not precede iron working. [1]

  8. Cold-formed steel - Wikipedia

    en.wikipedia.org/wiki/Cold-formed_steel

    Weldability refers to the capacity of steel to be welded into a satisfactory, crack free, sound joint under fabrication conditions without difficulty. [1] Welding is possible in cold-formed steel elements, but it shall follow the standards given in AISI S100-2007, Section E. 1.When thickness less than or equal to 3/16" (4.76mm):

  9. Carbon steel - Wikipedia

    en.wikipedia.org/wiki/Carbon_steel

    Carbon steel is heated to approximately 550 °C (1,000 °F) for 1 hour; this ensures the steel completely transforms to austenite. The steel is then air-cooled, which is a cooling rate of approximately 38 °C (100 °F) per minute. This results in a fine pearlitic structure, and a more-uniform structure.
