Abstract

After nearly 50 years of development, China's hydraulic industry has gained considerable production strength and technological level. With the significant improvement of China's equipment manufacturing industry, the hydraulic industry has formed a relatively complete industrial system with certain production capacity and technological level. Large scale complete sets of equipment can basically meet the needs of national economic development. Welding technology plays an important role in the manufacturing industry, and the quality of welding directly affects the safety, reliability, and service life of products. This article focuses on the key links in the welding production, manufacturing, and quality system assurance of hydraulic cylinder flanges, cylinder heads, and cylinder barrels for Zhejiang Huachang Hydraulic Machinery Co., Ltd. It analyzes the application of welding technology in the production and manufacturing process, explores the establishment and implementation of the welding quality system assurance system, and looks forward to the future development trends of welding production, manufacturing, and quality assurance.
