搅拌头是搅拌摩擦焊的关键技术.采用圆柱形搅拌头,进行铝合金薄板对接搅拌摩擦焊工艺试验.试验过程中,通过改变搅拌头肩部及搅拌针的尺寸,分析其对焊接过程及焊缝质量的影响.结果表明:对于厚度为3 mm的铝合金板材,当采用搅拌针直径为3 mm、肩部直径为9 mm的圆柱形搅拌头施焊,在合理的焊接工艺参数下施焊,可获得质量良好的焊接接头.
攪拌頭是攪拌摩抆銲的關鍵技術.採用圓柱形攪拌頭,進行鋁閤金薄闆對接攪拌摩抆銲工藝試驗.試驗過程中,通過改變攪拌頭肩部及攪拌針的呎吋,分析其對銲接過程及銲縫質量的影響.結果錶明:對于厚度為3 mm的鋁閤金闆材,噹採用攪拌針直徑為3 mm、肩部直徑為9 mm的圓柱形攪拌頭施銲,在閤理的銲接工藝參數下施銲,可穫得質量良好的銲接接頭.

The design of stir-welding head geometry is the key for friction stir welding. In this paper, FSW process test of butt joints of aluminium alloys sheet was carried out. The influence of stir-welding head on welding process and welding quality by changing the diameter of the shoulder and probe is analyzed. The results of experiments show that the optimal size of cylindrical stir-welding head for 3 mm thick aluminum alloys sheet is that the diameter of shoulder is 9 mm and the diameter of pribe is 3 mm.
