joining is one of the manufacturing processes by which two or more materials can be permanently or temporarily joined or assembled together with or without the application of external element in order to form a single unit.
types of joining processes
Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure, or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood.
process that may be used power for fixing the parts together by engrossing and facilitating the use of metal part known as the rivet.
5- Adhesive joining
i s the process of joining two surfaces together, usually with the creation of a smooth bond. This may involve the use of glue, epoxy, or one of a wide range of plastic agents which bond either through the evaporation of a solvent or through curing via heat, time, or pressure
Sintering is a heat treatment process where loose material is subjected to high temperature and pressure in order to compact it into a solid piece. This is
s imilar to when ice cubes adhere together in a glass of water due to the temperature difference between the ice and the water, or when you push snow together to form a compact snowball.
