摘要
针对Q235钢开展了摩擦叠焊单元成形焊接试验并对在主轴转速5 000 r/min,塞棒进给速度0.3 mm/s条件下的焊接接头的显微组织和显微组织硬度进行了测试,分析了摩擦叠焊单元成形焊接接头中不同位置的金相组织结构与摩擦焊接过程中温度和压力之间的关系,以及接头中不同位置处显微组织硬度存在差异的原因。该研究对Q235钢摩擦叠焊焊接工艺参数的研究及提高焊接接头的质量具有一定的指导意义。
The friction stitch welding unit forming experiment has been carried out for Q235 steel.The microstructure and microhardness of the welded joints with 5 000 r/min rotation speed and 0.3 mm/s feed speed have been tested.The relationship between microstructure,welding temperature and welding pressure of different position in the joint has been analyzed.For the study of Q235 steel welding process and how to improve the welding quality,this research has certain significance.
