Trace generation of friction stir welding robot for space weld joint on large thin-walled parts
Purpose – The weld joint of large thin-wall metal parts which deforms in manufacturing and clamping processes is very difficult to manufacture for its shape is different from the initial model; thus, the space normals of the part surface are uncertain. Design/methodology/approach – In this paper, an effective method is presented to calculate cutter location points and to estimate the space norm...
متن کاملTorque based weld power model for friction stir welding
For decades, models have been developed for predicting the size of the weld nugget and heat affected zones in fusion welded structures. The basis for these models is the welding heat input, which is fairly well understood for most arc welding processes. However, this traditional approach is not as straightforward for friction stir welding (FSW). To date, no definitive relationship exists to qua...
متن کاملCFD Modelling of Friction Stir Welding of Aluminum to Steel butt joint
In this article effects of friction stir welding (FSW) tool rotational and traverse speeds were studied on heat generation and temperature distribution in welding zone of AA1100 aluminum alloy and A441 AISI joint. Computational fluid dynamics method was used to simulate the process with commercial CFD Fluent 6.4 package. To enhance the accuracy of simulation in this Study, the welding line that...
متن کاملEffect of Post-weld Heat Treatment on Joint Properties of Dissimilar Friction Stir Welded AA2024 and AA7075 Aluminum Alloys
In present study, the effect of heat treatment after friction stir welding dissimilar welds T6-7075 and T4-2024 aluminum alloys were investigated. Friction stir welding was performed at a constant rotation speed of 1140 rpm and welding speed 32 mm/min. After welding samples are taken under various heat treatment processes at different aging temperature and time period. Microstructural observati...
