摘要
装甲钢是一种用于作战装备的保护性合金材料,装甲钢的焊接是装甲钢结构的主要连接方式。从装甲钢的裂纹类别、特点以及其形成原因出发,介绍了装甲钢焊接材料、焊接工艺和提高焊接接头性能的措施。主要包括奥氏体焊条、铁素体焊条及奥氏体/铁素体双向焊条;电弧焊、CO2气体保护焊、熔化极气体保护焊、修复装甲钢裂纹的铝热焊、机器人焊,激光焊等焊接工艺;焊后热处理、超声波冲击法、焊趾砂轮打磨法与钨极电弧焊法。并在装甲钢焊接技术研究现状分析的基础上,提出装甲钢焊接技术今后的改进措施与发展方向。
The armor steel is a kind of protective alloy material which is used in a variety of combat equipment.The welding is a main joining method of armor steel structure.On the base of crack category,characteristics and formation causes of armor steel,the welding materials and welding processes of armor steel,and the measures taken to improve the properties of welded joint were introduced.Those include austenite welding electrode,ferrite and austenite/ferrite dual phase welding electrodes,the processes of arc welding,CO2 gas protection welding and thermit welding of armor steel crack repairing,and the measures taken to improve the properties of the welded joint of heat treatment after welding,ultrasonic impact,toe grinding and tungsten arc welding.The improving measures and development direction of armor steel welding were put forward by analyzing the armor steel welding processes.
