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.

This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties.
Compatibility controls the partitioning of different elements during melting. The compatibility of an element in a rock is a weighted average of its compatibility in each of the minerals present. By contrast, an incompatible element is one that is least stable within its crystal structure.
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.
It can be found as a mineral (chemical formula: (Fe,Os,Ru,Ir)). It is not only schapbachite that had a longer controversy. Other minerals have a complicated history, as well. Imogolite, 9.ED.20, was first published 1962. [35] [36] Its formal discreditation by the IMA was published 1967, as its description was incomplete. [37]

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
