钢质药筒的焊接生产是药筒生产中一种较年轻的工艺。它对各种药筒的适应性和良好的战时动员性给药筒生产开创了一条“以钢代铜,以焊代冲”的新途径。尤其是它在大口径药筒生产中所表现的低成本、高效率,小设备,省能源等诸方面的优势正引起人们广泛的兴趣。 Welding of steel cartridges is a relatively young process in cartridge production. Its adaptability to a variety of cartridges and good wartime mobilization created a new way of producing cartridges by using steel instead of copper and surpassing them with welding. In particular, its advantages in low-cost, high-efficiency, small equipment, and energy-saving performance in the production of large-caliber cartridges are attracting a great deal of interest.
