In the context of continuous industrial development, metal welding plays an incredibly important role in creating and maintaining a wide range of products and societal infrastructure. From automobile and machinery production to the construction of bridges, tunnels, and road systems, metal welding has become an indispensable part of modern life. To better understand what metal welding is, let’s explore the following article

What is metal welding?

Metal welding is the process of joining two or more metal pieces by melting their parts or using high pressure without requiring a melting temperature. The metal welding process typically involves the use of high temperatures or electrical systems to melt the contact areas of the metal pieces, allowing them to cool and solidify to create a strong and secure connection.

There are various techniques in metal welding, including spot welding, arc welding, MIG/MAG (metal inert gas or metal active gas) welding, TIG (tungsten inert gas) welding, and many other methods, each with its own specific applications in the industrial and construction sectors.
