    - The welding processes are classified as follows:

    1. Pressure welding

    2. Fusion welding

    3. Modern or Miscellaneous welding

    - The metal joined is never brought to a molten stage in pressure welding

    - The metal is heated to a welding temperature which is below the melting point of that metal and joining is brought by application of pressure.

    - Forge welding and resistance electric welding are the example of pressure welding.
