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.

In welding, equivalent carbon content (C.E) is used to understand how the different alloying elements affect hardness of the steel being welded. This is then directly related to hydrogen-induced cold cracking, which is the most common weld defect for steel, thus it is most commonly used to determine weldability.
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.

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.
Welder certification is based on specially designed tests to determine a welder's skill and ability to deposit sound weld metal. The main part of the welder's test consists of welding one or more test coupons which are then examined using non-destructive and destructive methods.
ArcelorMittal South Africa is part of the steel company Arcelor-Mittal. [ 1 ] [ 2 ] The company was originally Iscor Ltd. , a South African parastatal steel company. It was founded in 1928 and was first listed on the JSE Securities Exchange in 1989.
Workers welding in parking garage. Welding is the main focus of steel fabrication. [8] Formed and machined parts are assembled and tack-welded in place, then rechecked for accuracy. If multiple weldments have been ordered, a fixture may be used to locate parts for welding. A welder then finishes the work according to engineering drawings (for ...
