Welding is a key link in the connection of cold storage copper pipelines, which directly determines the pipeline tightness and system cleanliness. Irregular welding is likely to cause two core hidden dangers: leakage and impurities entering the system, which seriously affect the stable operation of the refrigeration system and increase maintenance costs and safety risks.

         Irregular welding will lead to poor sealing of pipeline interfaces, causing refrigerant leakage, resulting in reduced refrigeration efficiency and soaring energy consumption. At the same time, it may erode surrounding components, intensify equipment wear, and even affect the quality of stored goods, laying potential safety hazards.

         Improper operation during welding is prone to generate impurities such as welding slag and oxide scale. After these impurities enter the refrigeration system, they will block pipelines, valves and heat exchangers, hinder refrigerant circulation, damage core components such as compressors, and induce system failure and shutdown.

         Such hidden dangers originate from the welding construction link. It is necessary to standardize the welding operation process, strictly control the welding quality, do a good job in cleaning and testing after welding, eliminate leakage and impurity residue problems, ensure the pipeline is well-sealed and the system is clean, and lay a solid foundation for the operation of the cold storage refrigeration system.
