An economical capacitor-type welding device and capacitor-type welding method that have a small power loss, that can be made compact, and that reliably control a charging circuit without being affected by the inductance of a charging path. In an exemplary capacitor-type welding device and an exemplary capacitor-type welding method of the invention, a bypass switching element having a forward-blocking function is connected in parallel to output terminals of a charging circuit, and the bypass switching element is brought into a conduction state to allow a backflow current, which is caused to flow by a magnetic energy stored in the inductance of a primary winding or an inductor included in the charging path, to bypass the charging circuit. A discharge switching element is brought into a conduction state after the bypass switching element enters the non-conduction state and recovers the forward-blocking function.
摘要:
A discharge welding system for discharge welding a welding member such as a stud to a weld surface such as a battery terminal or strap. The discharge welding system generally includes a power source which is electrically connected to both a clamp and a retainer such as a collet. The clamp is utilized to secure a conduction member such as a washer against a weld surface such as a battery terminal or strap. The retainer is utilized to removably retain a welding member such as a stud which is adapted to be welded to the weld surface. A weld actuator is adapted to lower the retainer such that the welding member contacts the conduction member to complete an electrical circuit as an electrical current is discharged by the power source. The welding member is welded to the weld surface by the electrical current discharge.

A torque transmitting assembly is provided. The torque transmitting assembly includes a generally cup shaped outer shell having a closed end and an open end. The closed end has at least one raised portion formed therein. The outer shell includes an outwardly extending lip surrounding the open end of the outer shell. The open end of the outer shell is adapted to be operatively engaged with a first rotating member. A generally disk shaped inner member has a central aperture and a central axis. The inner member includes at least one tab extending axially outwardly therefrom and engages the raised portion of the outer shell to facilitate a transfer of rotation between the outer shell and the inner member. The central aperture is adapted to be operatively engaged with a second rotating member. The inner member is received inside said outer shell.
