The Huaheng HL3000-TIG longitudinal seam welding machine is widely used in the welding of products such as food machinery, dyeing and finishing equipment, power switch busbar cylinders, medical machinery, and special material chemical containers. It is mainly targeted at the longitudinal seam welding of medium and thin-walled cylinders less than 3000 mm long.

This equipment adopts the single-torch TIG welding process, and the welding torch is also equipped with the functions of OSC (Oscillation of Arc Length) and AVC (Arc Voltage Control for Arc Length Tracking). It comes with a high-definition welding monitoring system, which can make real-time fine adjustments to the welding speed and control the dynamics of the welding torch. It has greatly enhanced the accuracy and stability of welding, thereby improving the efficiency of welding production and the quality of welded products.

The company currently has one research and development center and three production bases, as well as twelve subsidiaries both domestically and internationally. The company employs nearly a thousand staff members. The technical research and development center covers an area of nearly 40,000 square meters and includes the Overseas Welding Technology International Joint Laboratory, Jiangsu Province Welding Automation Equipment Key High-tech Research Laboratory, Jiangsu Province Robot Automation Equipment Engineering Laboratory, and a National Enterprise Postdoctoral Research Workstation. The company has successfully undertaken and completed 16 national-level scientific and technological projects related to machine applications and intelligent equipment, including the National High-tech R&D Program (863 Program), Torch Program, Key National Products Program, and Major National Science and Technology Projects. It has participated in the formulation of six national and industry standards related to welding robots, spraying robots, and automated welding communication. The company is a national-level demonstration enterprise for intellectual property rights and has been granted 435 authorized patents (including 140 invention patents), 200 software copyrights, and 48 registered trademarks in China.

The company has established production facilities in Kunshan, Xuzhou, and Changsha, with a total area of over 180,000 square meters. Its main products include automated welding production lines, intelligent logistics and warehousing systems, automated welding and cutting equipment, as well as planetary gear reducers. The business covers various stages such as project planning, research and development, design, complete equipment production, assembly, integrated debugging, and sales, providing turnkey engineering services for overall solutions.

The company's products are widely used in the high-end equipment manufacturing fields of engineering machinery, shipbuilding, rail transportation, aerospace, marine engineering, military, and nuclear power, as well as important industries in the national economy such as petrochemicals, food, and healthcare. They are also exported to countries and regions such as the United States, Europe, India, Brazil, and Southeast Asia.
