摘要:
為了消除攪拌摩擦點焊固有的“匙孔”缺陷,采用無針攪拌摩擦點焊(probeless friction stir spot welding,P-FSSW)工藝,在不同的焊接參數下對新型鋁鋰合金2198-T8進行了點焊試驗,并分析了點焊接頭的金相組織及其力學性能。結果表明,無針攪拌摩擦點焊工藝可以有效消除“匙孔”缺陷,但受工藝限制,無針攪拌摩擦點焊焊接工藝較適用于低熔點合金及薄板焊接。
Abstract:
In order to eliminate the keyhole which appeared normally in conventional friction stir spot welding (FSSW) joints, 2198-T8 Al-Li alloy had been taken spot welding by probeless friction stir spot welding (P-FSSW), and metallographic structure and mechanical property of welded joint were analyzed. The results showed that P-FSSW process could effectively eliminated the keyhole defect, but limited to the process, P-FSSW process applied to low-melting-point alloy and sheet welding.
