Abstract

In order to find the ideal process parameters, the friction stir welding (FSW) is assessed with a mathematical optimisation technique in this paper. In terms of optimisation, the objectives are process-related in that they define or represent how the process behaves. Since the FSW is solid-state and does not involve melting, many of the problems of conventional fusing welding techniques may be avoided. In FSW process, two work pieces are submerged in a spinning tool. As a result of friction and plastic dissipation, the temperature rises to the point where the material is sufficiently softened to be mixed together, forming a weld. Involving solid material, heat transmission, thermal softening, recrystallization and the production of residual stresses, the process is multi-physics in nature.
搅拌摩擦焊工具RS/AS和熔核区SEM分析及参数优化数学方程
为了找到理想的搅拌摩擦焊工艺参数,本文采用数学优化方法对搅拌摩擦焊进行了评定。就优化而言,目标与流程相关,因为它们定义或表示流程的行为方式。由于FSW是固态的,不涉及熔化,因此可以避免传统熔焊技术的许多问题。在FSW工艺中,两个工件浸泡在一个旋压工具中。由于摩擦和塑性耗散,温度上升到材料充分软化以混合在一起形成焊缝的程度。该过程涉及固体材料、传热、热软化、再结晶和残余应力的产生,本质上是多物理场的。
