Welding is one of the most essential industrial processes in our world today, with global spending on welding materials estimated to be over $90 Billion USD in 201 An estimated 400 million tons of welding materials are produced around the world annually.
Welding is used to join two pieces of metal together and is an important skill involved in a wide range of industries. So, what is welding for? The answer is simple: welding is used to make structures stronger and more efficient, as well as to form new shapes and objects.
By joining metal pieces together, it becomes possible to construct components for industries like aerospace, automotive and construction, to name a few. Welding is also used to connect metal components in electrical and plumbing systems, and is an important factor in the production of consumer products.
In short, if you can make it, you can probably weld it.
What is Welding?
Welding is a fabrication process that joins metals or thermoplastics by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.Types of Welding Processes
Welders can use different processes to join metal and other materials. Some of the most common welding processes include:- Gas Metal Arc Welding (GMAW) – Also known as “mig” welding, this process is fast, economical, and widely used for welding steel and aluminum.
- Gas Tungsten Arc Welding (GTAW) – This is also known as “tig” welding, and it is primarily used in the automotive, aerospace, and fabrication industries. It is more popular for small welds, thanks to its greater precision.
- Shielded Metal Arc Welding (SMAW) – This is a very common welding process, and it’s often used in the construction of steel structures. It requires a stick electrodes to transfer the weld.
- Submerged Arc Welding (SAW) – This is a high-speed, automated welding process that uses a flux-coated electrode.
- Flux-Cored Arc Welding (FCAW) – This is similar to GMAW, as it uses electricity and a wire electrode to generate heat for the weld.
