[0002] Pipeline welding is a basic process to ensure the safe and efficient transmission of various fluids. It plays a key role in many industrial fields. High-quality welding can prevent leakage and protect the environment. Pipeline welding and docking are key technical operations to ensure the integrity, stability and safety of fluid transmission systems. It creates strong and sealed connection points to prevent safety hazards caused by internal medium leakage.
