What Does Weldability Mean?
Weldability is the ability of any material (usually metals and its alloys) to weld with similar materials. Many metals and thermoplastics can be welded together to fabricate a final material that is required further in the fabrication process or any other industrial process.
Weldability may also be known as joinability.
Corrosionpedia Explains Weldability
The weldability of any material helps to determine which welding process is appropriate for that material and also helps the inspection of the final weld quality.
Welding is a fabrication process in which metals and thermoplastics are joined with similar materials (i.e., metal can be joined with metal, thermoplastic with thermoplastic) by causing coalescence.
Welding creates a strong permanent joint and the welding process is used in many industrial sectors, including aerospace, automotive, shipbuilding, construction and the steel industries.
