5 Questions
Explain why joining processes may be preferred for manufacturing a product.
Joining processes may be preferred if the product is impossible or uneconomical to manufacture as a single piece, or if the product is easier to manufacture in individual components which are then assembled.
What are the three commonly used joining techniques?
The three commonly used joining techniques are mechanical joints, adhesives, and welding and allied processes.
Define welding and its purpose.
Welding is a process of permanently joining two materials, usually metals, through localized coalescence resulting from a suitable combination of temperature, pressure, and metallurgical conditions. It is used for fabrication and joining materials.
What are the different reasons for the need of joining processes?
Different properties may be desirable for the functional purpose of the product, and transportation of the product in individual components may be more economical than transporting it as a single piece.
Explain the range of welding processes based on the combination of temperature and pressure.
Depending on the combination of temperature and pressure, a wide range of welding processes has been developed, ranging from high temperature with no pressure to high pressure with low temperature.
Study Notes
Introduction to Welding Processes
- Welding is a joining process used when a product is impossible or uneconomical to manufacture as a single piece, or when individual components are easier to manufacture and assemble.
- Joining may be preferred for functional purposes and economical transportation of individual components.
- Three commonly used joining techniques are mechanical joints, adhesives, and welding and allied processes.
- Mechanical joints, adhesives, and welding joints are the three main types of joining techniques.
- Welding is defined as a process of permanently joining two materials, usually metals, through localized coalescence resulting from a combination of temperature, pressure, and metallurgical conditions.
- A wide range of welding processes has been developed, depending on the combination of temperature and pressure used.
- Welding is a fabrication process that joins materials, usually metals, by causing coalescence.
