purpose of Metal fabrication is building metal structures.
Fabrication shops and machine shops have overlapping capabilities, but fabrication shops generally concentrate on metal preparation and assembly as described above.
Blacksmithing has always involved fabrication, although it was not always called by that name.
The products produced by welders, which are often referred to as weldments, are an example of fabrication.
Metal fabrication involves the making of metal structures and components by manipulating the raw material – usually structural steel and sheet metal – through a range of processes. The term covers a broad range of activities, from sheet metal fabrication for construction projects, to machined parts and bespoke products for manufacturers.
Typical processes involved in metal fabrication include:
Once the parts have been made, they may need to be assembled. Assembly may involve welding, binding with adhesives, riveting, threaded fasteners or crimped seams.
The parts or assemblies may then be treated by a process of sandblasting, priming, painting or powder coating, if required.
