What Is Welding

The Latest Exploration And Understanding In 2023

Welding is a versatile process that employs heat, high temperature, or high pressure to seamlessly join various metals or materials together. The components being joined are referred to as parent materials, and the resulting connections are known as weldments. However, it is important to understand that different materials may react differently during the welding process due to their unique physical and mechanical properties.

For instance, the application of high-temperature heat during welding can alter the strength, ductility, and other characteristics of the metal, allowing for the straightening of warped metal. The primary objective of welding is to create a robust and uninterrupted material connection that matches the performance of the original raw material. Simultaneously, it is crucial to ensure that the welded joint possesses sufficient strength.

There are many types of welding classified by process, such as Arc welding, Oxygen fuel gas welding, Resistance welding, Laser welding, Ultrasonic welding, and Friction welding.

Arc welding: This is a common method that uses an electric arc to heat metals and join them together. In arc welding, electric current passes through the air gap between the welding electrodes, creating a high-temperature arc that heats the workpiece to the melting point. This process is usually done using a welding machine and a welding rod (wire).Such as construction and infrastructure and aircraft parts welding.

Oxygen fuel gas welding: It is a welding method that uses a high-temperature flame generated by the mixed combustion of gas and oxygen to heat the metal, melt the weldment and the welding material to achieve interatomic bonding. The combustion-supporting gas is mainly oxygen, and the combustible gas mainly uses acetylene, liquefied petroleum gas, etc.Like the wings of an airplane.

Resistance welding: The principle of resistance heating produced by the metal workpiece when electric current passes through is used to connect two metal parts together. This method is often used for small parts or high-volume production. Such as silver contact soldering.

A welded joint is the area where two or more metal parts are connected during the welding process. This area is formed by heating the metal to a high enough temperature that it partially or completely melts, and then as it cools. The quality of welded joints directly affects the strength and performance of the welded connection.Common welded joints include Butt Joint,Lap Joint,Corner Joint,T-Joint,Pipe Joint,Cruciform joint,Edge Joint.
