Welding is a commonly used manufacturing process that uses heat, pressure and other variables to join two materials together, creating a strong bond and often a beautiful new form. It is a versatile process used in a variety of circumstances, from simple home repair jobs to complex industrial manufacturing and engineering, and it has been developing over centuries to become the powerful, reliable process it is now. According to D&M Welding, about 60 million tons of steel are welded every year in North America alone.
Even with this huge amount of work done each year, the process of Welding still has the potential to surprise and evolve, as it has many different applications and forms.
What is Welding?
Welding is a process used to join materials such as metal, plastic and other composite materials by melting them together.It is a fabrication or sculptural process that employs heat or pressure to join or cut materials. This is usually done with specialized equipment and tools, such as welding torches, blowtorches, spot welding machines, and welding rods.
Different Types of Welding
There are many different types of welding including:- Arc welding, which is often used for heavy-duty welding applications such as automobile frames, pipelines and bridges.
- Gas welding, which uses an oxygen and acetylene flame to join metal pieces, typically used in the repair of metals such as furniture or household tools.
- Tig welding, which creates a weld without any additional filler material.
- MIG welding, which melts two pieces together by passing an electric current through them.
