  WELDING

  Welding
  is the process of joining metals together with heat. Modern methods usually require four main components – the metals, a heat source, a filler material (sometimes referred to as a consumable) and a shield from the air.
  The concept has been around since the Iron Age, when blacksmiths invented ‘forge’ welding, a solid-state process where two pieces of metal are heated and then hammered together until they fuse. From 1800 numerous scientific breakthroughs led to welding advances such as experiments in arc production, the discovery of oxyacetylene and the invention of resistance welding.
  During the late 19th century and early to mid-20th century, growing railways, rapid industrialisation, increasing oil and gas production and the manufacturing demands of two world wars led to many improvements in welding techniques and the discovery of numerous new methods.
