Fabrication as the term signifies is the process of manufacturing or inventing something. Similarly metal fabrication is the mean of building of metal structures by cutting, bending and assembling processes.
This process involves the creation of machines, parts and structure from various raw materials. Different techniques have been used by metal production expert to produce customized parts, fitting, and other industrial and commercial solution. You can find more about techniques at https://medinaeng.com.au/.
The techniques used produces completely a different product with different characteristics. Each technique has its own purpose and benefits whether it’s bar milling, sheet metal fabrication, or press brake forming.
Various raw materials used by metal fabricators are plate metal, formed and expanded metal, welding wires and casting.
Based on customer needs many fabrication shops have specialty processes which they develop or invest in these are:
- Powder coating
- Powder metallurgy
So similarly if we talk about welding it is the process that joins materials, usually metals or thermoplastics, by causing fusion, which distinct from lower temperature metal joining techniques such as brazing and soldering that generally do not melt the base metal.
In welding two or more work pieces are joined together according to particular geometry. American welding society referred five types of joints which are butt, corner, edge, lap, and tee.
We have a manual welding method but it is still an exceptional method for plenty assemblies. But there are many assemblers who are implementing computerized welding system to boom, productiveness and profitability. You can check this post to find out how Robot welding automates the welding process.
We have welding automation which is divided into two categories i.e. Semi-automated and completely automated.
In semi-automatic welding, an operator manually masses all the elements into welding fixture whereas in completely automated welding process, a custom device masses the work pieces indexes the element, monitor the joint and unload the completed product.
If we have to differentiate between fabrication and welding we can say that fabrication is making something and welding is just one operation performed during a fixture process.
