Welding process flow

The development of the welding process requires consideration of many factors, including the nature of the material to be welded, the choice of welding method, and the structural type and welding performance requirements of the weldment. Generally speaking, the welding process includes the following steps:

The principle of welding is based on solid bonding between metals, and the specific formation process involves several key aspects.

First, the metal at the connection site is heated to a molten state, which is called melting core. When the temperature is high enough, the surface tension of the material being welded is reduced, allowing the molten metal (solder) to wet the substrate and solidify to form a strong contact as the temperature decreases.

Principle of welding

The principle of welding is the process of binding two or more metal workpieces together by heating them to a molten state and then allowing them to cool and solidify. Depending on the welding method, this process may involve generating enough heat to melt the metal through an electric arc, gas flame, laser, or other heat source.

Welding nut

Welding nuts are fasteners used with bolts and screws, often made of weldable materials so that they can be joined by welding. When selecting the welding nut, attention should be paid to the adjustment of its fusion size and welding parameters to ensure the welding quality. Resistance welding is one of the best welding methods, especially the projection welding method, and carbon dioxide welding can also be used to replace some welding methods. When performing welding operations, the nature of the material to be joined needs to be taken into account, such as active metals such as aluminum and magnesium may require special welding techniques such as argon arc welding
