Materials


Materials:

The  material can be termed as a mixture of materials to compose a thing.

Lots of definitions of material have spread to our surroundings. But we will be discussed here the materials, that are eligible for welding.

Materials

                               Iron 

Materials can be classified into four main groups:  

    • Metal
    • polymers,
    • ceramics, and
    • composites. 
     

Materials

                   Carbon 






A combination of metal and non-metal becomes "steel"

Metal makes steel with a mixture of Non-metal like carbon and iron.
