Abstract: With rapid development of China’s long-distance pipelines, the requirements on pipeline constructors become higher and higher in the areas of technology and equipment, specialized management, and environmental protection. Modern pipeline construction has an urgent demand for development of a new-structured, energy-saving and environmental-friendly welding engineering vehicle. The integrated welding engineering of HMW-80B energy-saving and mute type adopts a new electricity-generation and welding integration technology and changes the traditional structure of welding engineering vehicle. The transmission structure of engine, electricity generator and hydraulic pump is creatively designed to improve transmission efficiency and electricity stability and apparently reduces energy consumption and accident rate. The transportation cost is effective reduced owing to reduction of the vehicle’s overall weight and size. Based on appraisal by the authoritative departments and field application, energy consumption is reduced 40 percent as compared to the products of the same kind, while noise falls reduced 70dB, making the vehicle a technological leader in China.
