Abstract

The friction stir welding (FSW) procedure is the main topic of this research study among the various welding techniques. The study focuses on the interaction between the mechanical properties of 3003 aluminum alloy and the process parameters (rotation speed, welding speed, and dwell time) in the form of rolled plates of 2 mm thickness, end-to-end and welded at 90° and 45°. The welds were made by varying the speed of rotation (1000, 2000 rpm) and setting the tool feed at 500 mm/min. This experimental approach is also based on varying the tilt of the welding tool from 0° to 2°. It has been shown that the studied parameters play an important role in the characterization and optimization of the above mentioned weld joints. Therefore, and based on the results obtained, the use of the 90° joint remains the best in terms of strength.

搅拌摩擦焊接铝合金的机械性能与工艺因素之间的关系

在各种焊接技术中，搅拌摩擦焊（FSW）工艺是本研究的主要课题。研究的重点是 3003 铝合金的机械性能与工艺参数（旋转速度、焊接速度和停留时间）之间的相互作用，其形式为厚度为 2 毫米的轧制板，端对端并以 90° 和 45° 焊接。通过改变旋转速度（1000、2000 rpm）和将工具进给设定为 500 mm/min，进行了焊接。这种实验方法还基于将焊接工具的倾斜度从 0° 调整到 2°。实验结果表明，所研究的参数在上述焊接接头的特征描述和优化方面发挥了重要作用。因此，根据所获得的结果，使用 90° 接头在强度方面仍然是最好的。
