【摘要】：清洁生产是制造工艺过程中追求的目标。搅拌摩擦焊是一种比目前最好的传统焊接工艺更好、对环境损害更低的连接技术。搅拌摩擦焊工艺的能量效率高、无耗材、无损耗、无辐射。因此,它是一种能获得优质焊接接头的清洁焊接工艺。但它在焊接过程中会产生缺陷,为使其成为一种可靠的生产工艺,需要对其进行进一步优化。本文作者对搅拌摩擦焊接头的缺陷进行表征。结果表明,缺陷的产生是由于焊件过程的产生的热量不够、搅拌针附近的物质移动不充分、搅拌针后部的材料致密化不够。焊接过程中产生的热量和物料的搅拌程度取决于搅拌摩擦焊的焊接参数。焊接参数选择不当,可导致缺陷的产生。本文所得结果来源于文献和实验。根据各种缺陷的特征,如其可能产生的位置、减少缺陷产生的主要参数等,提出了减少缺陷产生的一些措施。
[Abstract]:Cleaner production is the goal of manufacturing process. Friction stir welding (FSW) is a kind of connection technology which is better than the traditional welding technology and has lower environmental damage. Friction stir welding process of high energy efficiency, no consumables, no loss, no radiation. Therefore, it is a clean welding process that can obtain high quality welded joints. In order to make it a reliable production process, it needs to be further optimized. The author characterizes the defects of friction stir welding joint. The results show that the defect is caused by the insufficient heat produced in the welding process, the insufficient material movement near the stirring needle and the insufficient densification of the material behind the stirring needle. The heat produced during welding and the stirring degree of materials depend on the welding parameters of friction stir welding. Improper selection of welding parameters may lead to defects. The results obtained in this paper are derived from literature and experiments. According to the characteristics of various defects, such as the possible location and the main parameters of reducing the defects, some measures are put forward to reduce the defects.
