What is welding phenomenon
Welding is a process that uses heat or pressure, or both, to form an atomic or intermolecular bond between two or more metal or non-metal materials at the junction. The welding phenomenon is widely used in manufacturing, construction, aerospace and other fields, and is one of the indispensable technologies in modern industry. This article will combine the hot topics and hot content in the past 10 days to introduce in detail the definition, classification, application and latest technological progress of welding phenomena.
1. Definition of welding phenomenon
Welding refers to the atomic or molecular level bonding of two or more materials at the joint through physical or chemical methods. During welding, materials are typically heated to a molten or plastic state and then cooled and solidified to form a strong connection. Welding can be used not only on metal materials, but also on non-metallic materials such as plastics and ceramics.
2. Classification of welding
According to the energy source and process characteristics during the welding process, welding can be divided into the following categories:
| Welding type | Features | Application areas |
|---|---|---|
| arc welding | Use arc to generate high temperature to melt metal | Construction, ships, pipelines |
| Gas shielded welding | Use inert gas to protect the molten pool | Automobile manufacturing, aerospace |
| laser welding | High precision and high energy density | Electronic equipment, precision instruments |
| friction welding | Welding through frictional heat generation | Rail transit, energy equipment |
