Welding Sockets & Spigots Manufacturers

What are the functions and structures of Welding Sockets & Spigots?

In the complex and precise welding process, Welding Sockets & Spigots are key components for connection and transmission. Their design and structure not only affect welding efficiency, but also directly affect welding quality and safety.

1. General structure of Welding Sockets
As a bridge between welding power source and welding gun or welding equipment, the structural design of welding sockets must take into account electrical performance, mechanical strength and durability. Generally speaking, welding sockets are composed of the following key parts.
Shell: The shell of the welding socket is usually made of metal, such as brass, stainless steel, etc., to ensure its stability under high temperature and current impact. The shell not only protects the internal electrical components, but also provides the necessary mechanical support through its solid structure. The surface of the shell is often treated with anti-corrosion to improve its corrosion resistance.
Contact system: The contact system is the core part of the welding socket. It is responsible for safely and stably transmitting the output current of the welding power supply to the welding gun or welding equipment. The contact system is usually composed of multiple precision-machined metal contacts. These contacts are in close contact with the welding gun or cable plug through springs or other elastic devices to ensure the continuity and reliability of current transmission. The contact system is also designed with arc and short-circuit protection safety mechanisms to cope with emergencies.
Insulating materials: The application of insulating materials is very important inside the welding socket. They are used to isolate electrical components, prevent current leakage and short circuit, and ensure the safety of operators. Insulating materials are usually made of special plastics or rubbers that are resistant to high temperatures and arc erosion to ensure their stability under harsh working conditions.
Fixing and mounting parts: The welding socket also needs to be equipped with fixing and mounting parts so that it can be firmly mounted on the welding equipment or welding workbench. These parts may include bolts, nuts, brackets, etc. They are precisely processed and assembled to ensure that the welding socket will not loosen or fall off during use.

2. General structure of Spigots
As a key component in the welding process, the structural design of the welding nozzle or plug must meet the special requirements of the welding process. The welding nozzle or plug consists of the following main parts.

Main material: The main material of the welding nozzle or plug is usually made of special alloys or ceramic materials that are resistant to high temperatures and corrosion. These materials can withstand the high temperature and corrosive environment during the welding process to ensure the stability and durability of the nozzle or plug. The selection of the main material also needs to consider its conduction performance to the welding current and arc to ensure the welding quality.
Conductive part: The conductive part is the core of the welding nozzle or plug. It is responsible for transmitting the welding current from the welding socket to the welding workpiece. The conductive part is usually made of metal materials with high conductivity, such as copper alloy or silver alloy. In order to ensure the stability and reliability of current transmission, the conductive part also needs to be precisely processed and surface treated to reduce contact resistance and prevent arc erosion.
Cooling system: In some high-power or long-time welding applications, the welding nozzle or plug also needs to be equipped with a cooling system. The cooling system reduces the temperature of the nozzle or plug by circulating coolant or air cooling to prevent damage or performance degradation caused by overheating. The design of the cooling system needs to consider factors such as cooling efficiency, compact structure and ease of operation.
Working part: The working part is the part of the welding nozzle or plug that is in direct contact with the welding workpiece. It is designed into different shapes and sizes according to the welding process and workpiece requirements. In MIG/MAG welding, the working part may include a nozzle and a conductive nozzle; in TIG welding, it may include a tungsten electrode clamping device and a gas nozzle, etc. The design of the working part needs to ensure the stability of the welding process and the welding quality.

As key components in welding technology, the structural design of Welding Sockets and Spigots must take into account multiple factors such as electrical performance, mechanical strength, durability and safety. Through precise processing and assembly processes, these components can play an important role in the welding process, ensuring the stable transmission of welding current and the reliable realization of welding quality. With the continuous development and innovation of welding technology, the structural design of Welding Sockets and Spigots will also be continuously optimized and improved to meet more complex and diversified welding needs.
