Assembly is an important step for manufacturing solid products, especially when the shape of the product is complicated having multifarious geometrical features. It is neither feasible nor economical all the times to directly produce a product having intricate shape. In such scenario, making small simple parts and joining them together is the best possible way. Joining consists of a large number of processes used to assemble two or more parts together, irrespective of their composition, properties, features, shapes, etc.
By definition, 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. Now-a-days a large variety of such joining techniques are available to cater the need of assembling a wide variety of materials in various ways for various processing or applications. Some of the commonly used joining processes are enlisted below.
- Fasteners (including nut-bolt, nail, hook, clip, clutch, button, zipper, etc.)
- Adhesive bonding
- Resin bonding
- Cotter joint
- Knuckle joint, etc.
Topic: Welding – a permanent joining process
A permanent joining process does not allow easy dismantling of jointed parts without rupturing them. On the other hand, for temporary joints, jointed parts can easily be dismantled without any damage. Welding is the first and foremost example for permanent joining process where two or more materials can be joined by coalescence formation. On the other hand, fasteners, cotter joint, knuckle joint, etc. are examples of temporary joints.
There exist a number of various welding processes to weld a wide variety of materials in innumerable ways. Some of the common topics related to welding are enlisted below.
