Welding - Simple English Wikipedia, The Free Encyclopedia
Welding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. There are many kinds of welding, including arc welding, resistance welding, and gas welding.The most common type is arc welding. Anyone who is near arc welding needs to wear a special helmet or goggles because the arc is so bright. ... Read Article
