What are the 3 metal fabrication techniques?

Metal fabrication involves various techniques for shaping and manipulating metal into desired forms and structures. Three common metal fabrication techniques are:


Welding is a process that joins metal pieces by melting them together and allowing them to cool and solidify, creating a strong bond. There are several welding methods, including:
* Arc Welding: Uses an electric arc to generate heat and melt the metal.
* MIG (Metal Inert Gas) Welding: Uses a consumable wire electrode and a shielding gas.
* TIG (Tungsten Inert Gas) Welding: Uses a non-consumable tungsten electrode and a shielding gas.
* Spot Welding: Joins metal sheets by applying pressure and electrical current at specific points.
* Gas Welding: Uses a flame generated by a mixture of fuel gas and oxygen to melt the metal.


Machining is a subtractive manufacturing process that involves removing material from a workpiece to achieve the desired shape or finish. Common machining processes for metal fabrication include:
* Turning: Rotating the workpiece while a cutting tool removes material.
* Milling: Removing material using a rotating cutter with multiple teeth.
* Drilling: Creating holes in metal using a rotating drill bit.
* Grinding: Abrasive particles remove material to achieve precision and surface finish.

* Boring: Enlarging existing holes or creating precise internal features.

Sheet Metal Fabrication:

Sheet metal fabrication involves working with thin sheets of metal (typically less than 6mm thick) to create various components and structures. Common techniques in sheet metal fabrication include:
* Cutting: Shearing, laser cutting, or plasma cutting to cut and shape the metal.
* Bending: Using press brakes or rollers to create bends and angles in the sheet metal.
* Punching: Creating holes, slots, or other patterns in the sheet metal.
* Forming: Shaping the metal into complex three-dimensional forms.
* Assembly: Joining multiple sheet metal components using techniques like welding, fasteners, or adhesives.

These are just a few of the many techniques used in metal fabrication, and the choice of method depends on factors like the type of metal, the desired end product, and the precision required for the project.
