摩擦叠焊单元成型质量影响因素研究
Study on the influence factor for friction hydro pillar processing
摘要
Abstract
The welding parameters of friction hydro pillar processing play an important part in the welded joints' figuration and properties. Large numbers of welding processing experiments were conducted,and the welding quality, microstructure,macro features as well as the welding pressure of various parameters were tested. Besides, the cause of welding defects was analyzed and improvements were put forward.The results indicated that the microstructure of welded joints was regular and compact,and the welding defect was seldom when the spindle speed was above 3 500 r/min and welding speed was above 40 mm/min. The welding quality from the round head-round bottomed combination was better than the other combinations. Welding material's flowability at the transitional area of joints bottom was poor and the welding defects always occur nearby ,and this problem can be solved by using the round bottomed combination. Moreover,welding pressure also has a great influence on the welding quality.The acquired pressure history was in line with process of actual welding while the welding parameters were set properly.关键词
