Forge welding:
This welding is done by the black-smiths. In this two similar metal pieces are heated upto the plastic stage in the furnace. Then it is hammered so that a homogenous mixture is formed at the joint. The surface to be joined should be cleaned and made free from any foreign particle this is done by brushing.
