Description

Technical Field

[0001] This invention relates to the field of welding auxiliary equipment processing technology, and in particular to an auxiliary welding device for pipes used in refrigeration rooms. Background Technology

[0002] Welding of water manifolds plays a crucial role in HVAC engineering within cold storage refrigeration rooms. As vital storage areas for food and pharmaceuticals, cold storage refrigeration rooms require a stable temperature and humidity environment. Water manifolds are a critical component of this constant temperature and humidity system, collecting moisture from the air to keep the room dry, protecting equipment and minimizing water waste. Welding is a critical process in the manufacturing, installation, and maintenance of water manifolds. Proper welding securely connects the different parts of the water manifold, improving its overall strength and stability. It also allows for proper installation and connection to other equipment, ensuring the air conditioning system operates at constant temperature and humidity. Furthermore, welding facilitates easier repair and replacement of damaged or aging parts during maintenance and replacement, ensuring the continuous operation of the constant temperature and humidity system. Therefore, water manifolds play a vital role in HVAC engineering within cold storage refrigeration rooms, and welding is an indispensable key step in their production, installation, and maintenance. Proper welding ensures the strength, stability, and efficiency of the water collector, thereby guaranteeing a stable temperature and humidity environment in the cold storage refrigeration room.

[0003] However, during the pipe welding process between the water collectors and other equipment in the refrigeration room, the large cooling demand and the large size and weight of the water collector pipes and devices necessitate multi-person operation. This is not only time-consuming and labor-intensive but also poses a threat to the health and safety of the workers. Secondly, because the water collectors are sometimes installed in corners of the building, their operating space is limited, increasing the difficulty of installation and maintenance. This not only increases the danger to the operators but also the difficulty and time cost of the operation. In addition, when connecting the pipes of the water collectors, welding at height is sometimes required. This operation is difficult and requires more safety measures. Traditional manual welding methods require operators to work suspended at height, posing a threat to personnel safety and increasing the risk of operation.

[0004] How to solve the above-mentioned technical problems is the problem faced by this invention. Summary of the Invention
