A process of joining similar metals by application of heat with or without application of pressure and addition of filter material is called ______

Explanation:

Welding

• Welding is a metal joining process in which two or more parts are joined or coalesced at their contacting surfaces by suitable application of heat or/and pressure.
• Welding processes can be broadly classified into

1. Fusion welding
2. Pressure welding/solid-state welding

Nut and bolt joint

• Nuts and bolts are temporary fasteners used to join two pieces of solid material.
• In industry, the nut-bolt joint is widely known as a male-female joint.
• The nut is a female part and the bolt is a male part.
• Without bolt, a nut is useless

Soldering

• Soldering is the process by which metallic materials are joined with the help of another liquified metal (solder).
• A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two work pieces.
• Soldering iron tips are made of copper core plated with iron. The copper is used for heat transfer and the iron plating is used for durability.

Forming

• Forming can be defined as the process in which the desired size and shapes are obtained thought he plastic deformation of a material.
• The stresses induced during the process are greater than the yield strength but less than the facture strength of the material.
