Welding is a process of joining two or more similar or dissimilar metals with or without the application of heat, with or without the application of pressure, with or without the application of filler material.
Therefore, In this article, I will be explaining all the Classifications of the Welding Process in detail with the help of a tree diagram.
The welding Process is broadly classified into three types:
By melting of parent material, if the joint is produced called as Fusion Welding Process.
Fusion Welding Process is further classified as:
By burning of gases, the heat required for melting of plates is obtained called Gas welding operation.
By using electric arc, if the heat required for melting of plates is obtained called as Arc Welding Operation.
By using Exothermic Chemical Reaction, if the heat required for melting of plates is obtained called as Chemical welding process.
Without melting of parent material, if the joint is produced called a Non-Fusion welding process.
With the application of pressure, if the joint is produced called a Pressure welding operation.
The joining of two metals at room temperature with the application of a large amount of pressure is called cold pressure welding.
If two metals are joined at a temp less than -183 ̊C and with the application of a large amount of pressure called Cryogenic welding.
Even though resistance welding is classified under the non-fusion Welding Process but it is a fusion pressure welding operation.
On the whole, these are the different types of Welding processes in detail. I hope this article is helpful to you.
