MATERIALS

                               Iron 

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 can be classified into four main groups: 

• metals, 
• polymers,
• ceramics, and 
• composites. 

                   Carbon 

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

• Metal makes steel with a mixture of Nonmetal like carbon and iron.
