On June 10, a delegation of leaders from COSCO SHIPPING Kawasaki (Nantong) Marine Engineering Co., Ltd. paid a visit to Wuxi Hanshen Electric Co., Ltd. for inspection, research and on-site equipment testing. The core team of Hanshen extended a warm reception. Both sides conducted in-depth discussions focusing on intelligent ship welding, new green cleaning technologies and potential in-depth cooperation. As a benchmark enterprise in China’s high-end shipbuilding sector, COSCO SHIPPING Kawasaki (Nantong) has long committed itself to intelligent and eco-friendly shipbuilding. Adhering to stringent production processes and quality standards, the company sets high requirements for welding precision, weld formation, working efficiency and environmental compliance in ship manufacturing. The visiting leaders toured Hanshen’s equipment demonstration area to learn about the company’s R&D capabilities and practical application achievements across the industry. Hanshen’s four flagship products — handheld laser welders, laser cleaning machines, marine MIG/MAG welders and laser-arc hybrid welding systems — have been widely applied in the shipbuilding industry. They cover full working scenarios including hull construction, sectional plate welding, pre-weld treatment and equipment maintenance, and are compatible with manufacturing processes for various ship types. The delegation conducted thorough verification on the practical performance and technical strengths of these ship-specific welding solutions. To fully test the equipment under actual working conditions, the visitors brought special carbon steel workpieces for on-site welding tests. The handheld laser welder delivered smooth and firm welds with minimal thermal deformation, eliminating much of the subsequent grinding work and fully meeting the precision welding standards for ship components. The leaders also operated the equipment in person, and spoke highly of its light weight, flexibility, accessibility to narrow spaces and special-shaped components, as well as outstanding welding stability. The delegation also showed great interest in Hanshen’s laser cleaning machines and laser-arc hybrid welding systems. Featuring high efficiency and eco-friendliness without damaging base materials, laser cleaning equipment efficiently removes rust, paint and oil stains from steel plates and weld seams. It serves as an ideal replacement for traditional sandblasting and pickling processes, and is widely used in pre-weld treatment, hull renovation and maintenance. Tailored for sectional plate welding, the laser-arc hybrid welding system combines the advantages of laser deep penetration welding and arc welding. It is well suited for long welds on medium and thick plates, enabling one-side welding with back formation. This technology effectively controls welding deformation, greatly improves working efficiency and cuts costs on welding consumables and labor, making it an optimal solution for plate welding in high-end shipbuilding. Supported by the four core product lines, Hanshen has developed an all-in-one intelligent welding and cutting solution for shipbuilding, covering precision welding for thin plates, main welding for thick plates, high-efficiency plate welding and eco-friendly pre-treatment. With reliable performance, we have built a wealth of successful application cases and earned a solid reputation in the domestic shipbuilding industry. This on-site inspection and equipment testing by the industry leader fully proves the superior quality and strong adaptability of Hanshen’s professional welding and cutting equipment for ships, laying a solid foundation for further cooperation between the two parties. Going forward, Hanshen will continue to focus on the marine and offshore engineering sector, keep upgrading our intelligent, efficient and eco-friendly integrated welding and cutting technologies and equipment, and contribute to the high-quality development of China’s shipbuilding industry.
