Welding and Types of Welding
11 Types of Welding
Chemical welding-
During the welding process if the heat required for the plates is obtained due
to Exothermic Chemical Reaction is called as chemical welding.
Welding is a process of
joining two similar or dissimilar metals with or without the application of
heat with or without the application of pressure and with or without the
application of filler material.
Fusion welding- The
process of welding in which melting or fusing of parent material, joint is
produced called as fusion welding process.
Non-Fusion welding- The
process of welding in which without melting of parent material, if the joint is
produced is called as a Non-Fusion welding process.
Arc welding- In the
welding process if the heat required for melting of the parent material is
obtained due to the Electrical arc called as arc welding.
Gas welding- In the
welding process if the heat required for melting of the parent material is
obtained due to the burning of gases called as gas welding.
Thermite welding- Thermite welding is a chemical reaction liquid state welding process in which
pouring of super-heated molten metal around the joint to be welded with or
without the application of pressure.
Pressure welding- With
application of large amounts of pressure, If a joint is produced is called as
pressure welding operation.
Brazing- In this
process by using molten metal through capillary action, the filler metal is
drawn through the joint between the parent metal to create metallurgical bond.
Soldering- The welding process
below the temperature 450° C in which it is melted to join metallic surfaces.
Cold Pressure welding-
At room temperature itself with the application of large amounts of pressure,
if a joint is produced is called as cold pressed welding.
Cryogenic welding- The
welding in which a metal is cooled below the temperature -183° C and with the
application of large amounts of applying pressure, when the joint is produced
called as cryogenic welding.
