Welding and cutting processes are essential techniques used in metalworking. Welding involves joining two or more pieces of metal by melting them together, often using heat from an electric arc or gas flame. Common welding methods include MIG welding, TIG welding, and stick welding, each suited for different materials and applications. Cutting processes, on the other hand, are used to separate or shape metal. Techniques like oxy-fuel cutting and plasma cutting utilize high temperatures to slice through metal. These processes are vital in construction, manufacturing, and repair industries, enabling precise fabrication and assembly of metal structures.
