Metal fabrication is the process of building or repairing metal products using various techniques such as cutting, forming, and welding. Metal fabrication involves transforming raw metal into a finished product, often using specialized equipment and techniques. Types of metal fabrication: 1. Sheet metal fabrication: This involves cutting, bending, and assembling sheet metal to create a desired shape or form. 2. Pipe fabrication: This involves cutting, bending, and assembling pipes to create a desired shape or form. 3. Structural steel fabrication: This involves cutting, bending, and assembling structural steel to create a desired shape or form. 4. Welding: This involves joining two metal pieces together using heat and pressure. 5. Cutting: This involves cutting metal into desired shapes or sizes using techniques such as sawing, drilling, and shearing. 6. Forming: This involves shaping metal into a desired shape or form using techniques such as bending, rolling, and drawing. 7. Machining: This involves removing metal using techniques such as milling, drilling, and grinding. Metal fabrication techniques: 1.
