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.
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):

This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
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. The extent of certification is described by a number of variables, which include the specific welding process, type of deposited metal, thickness, joint design, position, backing, and others.
A572 steel is typically used in structural applications due to its high strength, ductility, weldability and corrosion resistance. [4] These applications include structural sections, reinforcing bars, bridges, skyscrapers and houses. [1]
The Southern African Institute of Steel Construction (SAISC) is an organization which helps building and construction in South Africa by serving to promote and develop companies providing steel-related products and services to the industry. [1]
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.
