Welder demonstrates oxy-fuel cutting

Welding – a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld.

Welding – 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
  • gas welding
  • Electron beam welding (EBW) – a fusion welding process. A beam of high-velocity electrons is applied to the materials being joined.

That’s engineering

  • inert
  • fusion – the act of combining or blending into a whole
