摘要： For the determination of the welding current to be used for the resistance welding of the overlap seam of container bodies, welding with a test body is carried out with a changing strength of welding current which in the test body produces a varying welding of the seam. The current strength varies from welding of this seam with a too high temperature to welding with a too low temperature. Along with this the welding current strength used in the welding is determined so that it is further determined at which point of the seam the welding has been accomplished and with what strength of welding current. By means of a mechanical and/or optical investigation of the welded seam it can then be easily determined where the seam has been correctly welded for the series production of container bodies from the same sheet material as the test bodies. When such a point or such a region of the seam is known the welding current used in the test welding can be taken as the welding current for serial production.

摘要： In spot welding, the condition tolerance for applying a large current in a short time into an aluminum alloy plate or the like is narrow, and also nugget crack sometimes occurs in spot welding. In the case of a mild steel plate, the expulsion sometimes occurs, and thereby a poor weld portion is formed. Due to a pickup removal operation from an electrode tip, the operating ratio is reduced. Here, a PAM control method is employed for raising or dropping a rectified and smoothed voltage EDC output to an inverter circuit, according to a certain set-up ratio in a predetermined time, instead of a conventional PWM control method. By this control method, the nugget can be formed in condition of low heat dissipation and high thermal efficiency. In addition, energy saving and power saving are achieved by using the PAM control method.

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： This power supply apparatus comprises a charging circuit for charging a capacitor. The charging circuit includes a transformer, a rectifying circuit, a switching element, an inductance coil and a freewheeling diode. The rectifying circuit full-wave rectifies an AC power supply voltage acquired on the secondary side of the transformer to provide a DC voltage as its output. When the switching element is turned on or becomes conductive, a DC current is allowed to flow through a circuit extending from a positive output terminal of the rectifying circuit through the switching circuit and the inductance coil to a negative output terminal of the rectifying circuit. Once the switching element is switched from its ON state to OFF state, a current based on the inductance coil flows in the forward direction of the diode through a closed circuit consisting of the inductance coil, capacitor and the diode such that the capacitor is charged with the freewheeling current.

摘要： A method for inspecting the quality of the resistance weld, in which the adhesive force between twisted wires, as materials to be welded in a welding portion, can be predicted on the basis of the inter-tip resistance between electrodes, so that the quality of the weld can be evaluated accurately. The method comprises the steps of: measuring a welding width of the welding portion; calculating a reference welding height of the welding portion from the measured welding width on the basis of a predetermined reference welding sectional area of the welding portion; passing the welding current through the welding portion until the height of the welding portion reaches the calculated reference welding height; and inspecting the state of welding of the twisted wires on the basis of a bottom value of inter-tip resistance of the pair of electrodes in an initial stage of conduction of the welding current.
