摘要
通过试验方法对比研究了焊接热循环对三种铝合金-钢过渡接头温度场及界面结合性能的影响。结果表明:焊接热循环对过渡接头复合界面结合强度具有显著的影响。同一焊接条件下,焊接热循环在新型四层过渡接头界面上产生的温度峰值明显低于目前广泛应用的两种三层复合过渡接头,前者焊接前后的性能也大大高于后者,即使采用小宽度焊接试样,其焊后性能仍能满足"高施焊温度、更大应力承载、结合界面更强"的舰船设计技术要求。
The effects of welding thermal cycle on the temperature field and properties of three kinds of AI-alloy/Steel structural transition joints （STJs） is studied through testing method analysis. The results show that the effect of welding thermal cycle is very remarkable on the bonding properties of STJs. Under the same welding condition, the peak temperature at the bonding interfaces of the new style four-layer Al-alloy/Ti/R/steel STJ are lower than that on widely-used three-layer STJs （Al-alloy/Al/steel and Al-aIloy/~/steel）. The performance of the former is obviously higher than that of the latter. Even if # applies narrower welding specimens, it can meet the technical requirements of higher welding temperature, larger stresses and better bonding performance in ship design.
