Milling is a machining process in which a rotating cutter removes material from a workpiece to create a specific shape or surface finish. It is typically used to create precision parts and components, such as those found in the aerospace, automotive, and medical industries.
Welding, on the other hand, is a process that joins two or more metal pieces by heating them to a high temperature and applying pressure or a filler material. There are different types of welding methods such as Arc welding, TIG welding, MIG welding etc. It is used in a wide range of industries, including construction, manufacturing, and repair and maintenance.
In short, milling is a process of cutting and shaping metal while welding is a process of joining metal pieces by heating and applying pressure.
