Corrosionpedia Explains Welding

Heating materials to their welding temperature often has an effect on their mechanical properties and their ability to resist corrosion. Care must be taken to ensure that a weld joint satisfactorily meets the requirements ascribed to it.

There are many different methods of welding together various types of materials, including:

  • Oxygen-fuel gas mixtures
  • Electrical arcs
  • Electrical resistance

Often times, noble gases such as argon or helium are used to shield the heated material from the atmosphere during welding.
