Title: Butt welding method
Inventor: MURAMATSU SHINYA
IPC: B23K11/02
Filed: 2000-02-24
Abstract: PROBLEM TO BE SOLVED: To perform burring in a short time. SOLUTION: Two stocks 1 to be welded are respectively set to electrodes 2 coaxially arranged, and the end surfaces of the stocks 1 to be welded are mutually butted. The butted parts are held by upper and lower forcing jigs. Both upper and lower surfaces being the long side of the stock 1 to be welded are held and both left and right side edges being the short side are released by the forcing jigs. Then, when the electric current is made to flow between both electrodes 2 in the state that the stocks 1 to be welded are compressed from the axial direction by the electrodes 2, the butted parts are joined and also burrs F are generated in this part. Since the burrs F are formed sticking out only to both left and right side edges of the butted part, the burring of the burrs F is finished by removing work from one direction in the succeeding process.
