The characteristics of pipeline welding processing are mainly as follows:

· High efficiency and high strength: As a metal joining technology, welding can provide very high joint strength and stability, making it suitable for pipeline systems that require high strength and durability.

· Good sealing: Welded joints can form a tight seal, effectively preventing leakage, especially in high-pressure or high-temperature working environments.

· Strong adaptability: Welding is suitable for a variety of metals and non-metallic materials, including common metals such as steel, aluminum, and copper, as well as some non-metallic composite materials.

· Simple construction: Welded joints do not weaken the cross-section of the component and are easy to process, allowing for the connection of various complex shapes and structures.

· Permanent connection: Once a welded joint is completed, it becomes an integral part of the workpiece, with high joint strength and stability.

· High efficiency and energy saving: Welded joints can be automated, improving production efficiency and saving material and time costs.

· Poor working conditions: The high temperature, sparks, and harmful gases generated during welding pose a threat to the health of operators, and appropriate labor protection measures need to be taken.

· High technical requirements: Welding requires welders to have a certain level of technical skills and operational experience, and different welding methods have different adaptability and welding quality for different materials.

These characteristics make welding a widely used joining method in pipeline engineering, especially in applications that require high strength and long-term stability.
