Answer :
Final answer:
Forge welding is the type of welding in which a projection is forced into a pool of molten metal, which solidifies around it. This creates a strong bond between the metal pieces being joined.
Explanation:
The type of welding in which a projection is forced into a pool of molten metal, which solidifies around it, is forge welding. In forge welding, the metal pieces to be joined are heated until they become soft and malleable. Then, a projection or a piece of metal is forced into the molten metal, and as it cools down, the molten metal solidifies around it, creating a strong bond.
