【導(dǎo)讀】以消除一些焊接缺陷，如裂紋和氣孔。為了證明2020-T351鋁合金在攪拌摩擦焊。當(dāng)最優(yōu)的旋轉(zhuǎn)前進(jìn)節(jié)距為，對應(yīng)于1500轉(zhuǎn)的旋轉(zhuǎn)速度和。焊接速度為100mm/min，接頭的最大極限強(qiáng)度相當(dāng)于母材強(qiáng)度的82%。有孔隙缺陷存在時，斷裂則在焊縫中心發(fā)生。攪拌摩擦焊是一種固相。因此，攪拌摩擦焊工藝可用于的熱處理鋁。導(dǎo)致接頭的力學(xué)性能的降低。2XXX系列的熱處理鋁合金的接頭，2020-T6512024-T3，2024-T3512024-T6被攪。2xxx的系列的熱處理鋁合金，并且至今沒有被攪拌摩擦焊。便確定FSW的最佳工藝參數(shù)，并找出接頭最薄弱的位置。品分別使用攪拌摩擦焊機(jī)縱向?qū)雍浮：附雍?，接頭垂直焊接方向交叉切割以便使用電器放電切割機(jī)進(jìn)行金相分析。對較高，并且隨著旋轉(zhuǎn)距離略有增加。任何接頭的斷裂位置直接反映共接頭同的薄弱部位。當(dāng)螺旋距離小于/轉(zhuǎn)，攪拌摩擦焊產(chǎn)生無缺陷接頭（見圖3（a）和。在圖4，在無效部分的硬度值不存在表示成“X”。
