Beschreibung
Zusammenfassung:	The utility model discloses an annular welding device used for welding an end cover and a connecting piece, the end cover is covered on the connecting piece to form a capacitor semi-finished product, the annular welding device comprises a rack, a first abutting piece, a second abutting piece, a telescopic driving mechanism, a rotary driving mechanism and a welding mechanism, the first abutting piece and the second abutting piece are coaxially arranged, and the first abutting piece is rotatably supported on the rack. The second abutting piece is used for abutting against one end of the capacitor semi-finished product, and the second abutting piece is used for abutting against the other end of the capacitor semi-finished product; the telescopic driving mechanism is connected with the second abutting piece to drive the second abutting piece to stretch out so as to clamp the capacitor semi-finished product between the first abutting piece and the second abutting piece. The rotary driving mechanism is connected wi
