摘要： A welding installation with a calibration tool is provided in a device for producing container shells. The force exerted by the container shells on the calibration tool is measured and evaluated as information for the overlapping width of the respective container shell. This allows adjusting the calibration tool during configuration of the device and allows the removal of container shells welded with too large or too small overlapping during production of container shells.

摘要： For spot-welding a plurality of metal workpieces, the metal workpieces are gripped and pressed under a pressing force by a pair of electrode tips, thereby forming a contact interface between the metal workpieces. Then, an electric current is passed between the electrode tips, and it is determined whether the contact interface is melted or not. Simultaneously when it is judged that the contact interface is melted, the pressing force applied from the electrode tips to the metal workpieces is reduced to such a level that the electrode tips and the metal workpieces are kept in contact with each other, the metal workpieces are kept in contact with each other, and the electric current keeps flowing between the electrode tips.

摘要： A method for monitoring a resistance welding process carried out on a stack of metal workpieces (1) clamped between two electrodes (2a, 2b) of a clamp (3), and a device therefor. According to the method, the electrodes (2a, 2b) are subjected to a clamping force (F) and a voltage (V(t)) enabling a current (I(t)) to flow through the stack of metal workpieces (1). The monitoring method further includes at least one step of analysing the clamping force (F) by comparison with a model from a prior learning process. The result of the analysis of each step is taken into account by a decision-making matrix to generate a correction and/or control signal intended for the welding process.

摘要： This invention provides a method of producing a series of substantially uniform spot welds between two metal parts using a servomotor driven movable electrode and an axially opposing fixed electrode. Target values for electrode displacement in producing a weld indentation and electrode squeeze force are determined for the electrodes and workpieces. During welding operations electrode displacement and electrode force measurements are continually taken and compared with the displacement and force target values. While the measured values are within a tolerance range of the target values, welding is continued using the preset parameters. When either or both of the measured electrode displacement or force value falls outside the target range the total welding current is adjusted in small increments to correct the displacement and/or force values and, thereafter, welding is continued using the new total welding current.

摘要： An adaptable, servo-control system for force/position actuation generally includes an electric linear actuator and a controller. The controller interfaces with the electric linear actuator and with a number of I/O signals that are independent from the electric linear actuator. The controller interface to the independent I/O signals is transparent to the manner in which the I/O signals are produced. Rather the controller simply looks for the status of the I/O that is preferably received into the controller by hard-wiring or field bus I/O messaging such as from a industrial robot or programmable logic controller. The adaptable servo-control system is particularly suited to resistance weld systems wherein the electric linear actuator can replace the pneumatic actuator providing position and force actuation of the weld tip of the welding gun.

The controller interfaces with the electric linear actuator and with a number of I/O signals that are independent from the electric linear actuator. The controller interface to the independent I/O signals is transparent to the manner in which the I/O signals are produced. Rather the controller simply looks for the status of the I/O that is preferably received into the controller by hard-wiring or field bus I/O messaging such as from a industrial robot or programmable logic controller. The controller utilizes the I/O signals to select a number of parameters to generate a motion profile for closed loop-controlled, position actuation or force actuation of the electric linear actuator. The adaptable servo-control system is particularly suited to resistance weld systems wherein the electric linear actuator can replace the pneumatic actuator providing position and force actuation of the weld tip of the welding gun.

摘要： The invention relates to a control device for spot welding with a welding electrode pincer (Z), the welding electrodes (E1, E2) of which are connected to a welding current generator (IS) and an electric motor drive (M), with a rotary transducer (RES), the signal of which is used by a control device (MP) to control the welding electrode pincer (Z). The closed state of said pincer holds the objects for welding (B1, B2) together, by means of a pre-set motor current (MAI), whereupon the welding current generator (IS) is activated. The control device (MP) comprises monitoring devices (const, max), to which the rotary transducer signals (RES) and/or a motor current measured signal (I(t)) are constantly supplied. Once a quasi-constant state is recognised, following a close signal for the welding electrode pincer (Z), a corresponding first state is recorded as the closed state and the welding current generator (IS) activated. Thereafter, as soon as the exceeding of a maximum value is reported, a further closed state is recorded, the welding current generator (IS) deactivated and a holding timer unit (CTT) activated, after the expiration (end) of which the on- and off-control of the welding electrode pincers is activated again.
