The principle of welding, how to form the solder joint

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.

Welding standard specification and process

Scope of application: The standard specifications of welding engineering are usually applicable to the manual arc welding of steel structures in general industrial and civil construction projects.

2025/06

Welding standards and processes are important guarantees to ensure the welding quality during the production and installation of steel structures

Materials and main tools: including welding rods, the model should be selected according to the design requirements. The external wiring of the welding equipment must be firm and reliable, especially the return route of the workpiece.
