Title: Butt welding method
Inventor: YAMAMOTO ATSUYUKI
IPC: B23K11/02
Filed: 1988-12-12
Abstract: PURPOSE:To prevent a third lip and a defective end shape at the time of butt- welding steel sheets by making a clamping pressure distribution of an electrode higher by specific % on both ends than on the central part in the cross direction of the steel sheets and performing welding with the upset force as a specific value. CONSTITUTION:The clamping pressure distribution of the electrode is made higher by 3-15% on both ends of the steel sheets than on the central part thereof and the upset force is regulated to 15-25kg/mm<2> to perform welding. Both ends having the slightly higher clamping pressure of the steel sheets has high current density and its temperature becomes higher and the temperature of the central part becomes lower. The third lip 1 is expected to be generated on the central part, but since the upset force is increased, deformation is forced even on a low temperature part and the generation of the third lip is prevented. Meanwhile, since the low temperature part takes place on the central part of the steel sheet width, constraining force in the cross direction thereof works and buckling is not caused and a normal upset shape is obtained. By this method, air leakage of a wheel is prevented and an excellent effect for improving the quality of a wheel rim is obtained.

Abstract: PURPOSE:To reduce the generation of an impact and impact noise by a method wherein a piston rod has the one end communicated to an oil chamber on the one side and the other end side communicated to an oil chamber on the other side, and an oil passage closed during widemost expansion of the piston rod is formed. CONSTITUTION:An oil hole 22B through which an oil chamber B is communicated to an oil passage 22A is formed in a piston rod 22 in a level slightly upper than that of a rebound stopper 18. A disc valve 23 serving as a check valve by means of which pressure oil in an oil chamber A can flow to the oil chamber B side through holes 21A is mounted on the upper surface side of a piston 21, and notches 23A forming a throttle passage are formed on the outer peripheral side of the disc valve. In which case, when the piston rod 22 is widely expanded in the direction of an arrow mark E, the oil hole 22B is closed. Since pressure oil in the oil chamber B gradually flows out to the oil chamber A side only through the oil holes 21A and the notches 23A, the expansion speed of the piston rod 22 is sharply reduced to relax collision of the rebound stopper 18 with a rod guide 4.
