摘要:
为了进一步降低冷凝器用铝合金复合管的泄漏率,采用金相试验对冷凝器用铝合金复合高频焊管焊缝气孔泄漏、显微裂纹泄漏和氧化物夹杂泄漏3种形式进行了分析,并从生产角度对焊缝泄露的原因进行了论证。研究结果表明,铝管坯纵切面不规整、导向环啃食成型开口圆管筒内侧边缘及焊接工艺参数控制不当等是冷凝器集流管焊缝泄漏的主要原因。针对以上泄露原因,提出了铝带纵剪分条优化工艺、导向环优化设计和焊接工艺参数优化等解决方案。实践证明,解决方案显著降低了冷凝器集流管焊缝泄漏率。
Abstract:
In order to reduce the leak-rate of aluminum alloy composite HFW pipe used in condenser,the pore leaking,microfissure leaking and oxide inclusion leaking were analyzed by metallographic test,and weld leaking reason was demonstrated from welded pipe production. According to the research results,the main reasons of weld leaking in collecting pipe of condenser were irregular longitudinal section of aluminium tube blank,inner wall notch caused by guide ring,and improper welding parameter control. For leaking reason,the optimizing solutions of aluminium tape slitting process,guide ring design, welding parameter were proposed. Production practice showed that the solutions reduced the leak-rate of collecting pipe weld observably.
