In order to weld 6 mm thick 6061-T6 Al alloy plate, bobbin-tools of various structural forms and sizes were designed and manufactured. The effects of structural forms and sizes on the welding process and the quality of the welded joint were analyzed. Two poses bobbin tool and three postures bobbin tool were designed and manufactured. The characteristics of the two forms of the structure were analyzed. Ring-shaped tool shoulder and concave-shaped tool shoulder were designed and manufactured. The results show that the quality of the weld by concave-shaped shoulder was better than ring-shaped shoulder. Four kinds of pin were designed and manufactured, those were pin with both right-hand thread and left-hand thread, pin with right-hand thread, cylinder pin and milling flat cylindrical pin. The results show that the quality of the weld by milling flat cylindrical pin was better than others. Using bobbin tool assembled by concave-shaped shoulder and milling flat cylindrical pin, 6 mm thick 6061-T6 Al alloy plates were welded under the spindle speed of 800 r/min and the welding speed of 150 mm/min. The tensile strength of the joint was 220 MPa, which was 70%of base material(Rm=315 MPa).
