About Welding And Its Different Types
Welding is the most widely practiced way of joining metals together because of the efficiency and economy of the process. It has been estimated that about 50% of the Gross National Product of the United States arises from the activities that are, in some form or another, related, perhaps remotely, to welding. As an example, farming may appear to have nothing to do with welding, but the equipment the farmer uses to grow and harvest crops will have used welding in their manufacturing process.

Until the advent of the 20th century, welding was confined to blacksmith shops where two pieces of metal were heated to very high temperatures in a forge and then hammered together until the joining occurred. This is what is called forge welding. With the introduction of electricity into industrial processes, welding become both easier and quicker, and also more economical. Today, there are four types of welding techniques commonly used.
