Welding technology is widely adopted in all small and large scale industries dealing with fabrication processes; it is also used for repairing and refurbishing metal products. Welding can be executed in all possible media, viz. air, space, and underwater. The process finds significant applications in automotive manufacturing; construction of residential, commercial, and industrial buildings; construction of bridges and other infrastructure; aerospace and defense; heavy machinery manufacturing; and all other fabrication industries or applications that require metal repairing.
Metal additive manufacturing is a technique in which a scanned or digitally designed object is formed into a 3D solid using an additive process. In this process, metal powder is applied in successive layers with little wastage and subject to a concentrated energy source that melts and shapes the metal. Additive manufacturing products can be built from various materials, plastic and metals being the most common materials.
