Summary:

Welding is a process that is used to connect two pieces of metal together, by heating them until they melt. However the gaps are filled with another material like welding rod or wire. There are many types of welding such as Gas Welding by mixing oxygen and acetylene; it is a common type of welding; also it is used for brazing, cutting and heating metal. Another type of welding is called Arc welding; it is working by electrical current. Another type is Spot welding to join small sheets of metal by electrical current. Each of these types of welding has different uses, especially for industry.

Reaction:

This article is un introduction of welding because there are many types of welding for different uses. The welding is like Art; it is very exiting and you have to be accurate. Also you have to take care if you want to be a wilder, because you are dealing with a high temperature and high electrical currents. You should wear a full PPE (Personal Protected Equipments) to do any type of welding. There is a welding underwater which is the most dangerous work in the world.
