摘要： In a resistance welding method, by controlling the power amount from a melting start time onward, the weld quality may be stabilized efficiently, even when a disturbance is present, because of the correlation between the amount of power input from the melting atart time and a resulting nugget. The resistance welding method includes: pressing an electrode (11a, 11b) against a workpiece (Wa, Wb); inputting power to the workpiece (Wa, Wb) through the electrode (11a, 11b) to subject the workpiece (Wa, Wb) to Joule heating; detecting the melting start time, which is the time at which at least a portion of the faying portion of a workpiece (Wa, Wb) starts to melt when subjected to Joule heating; calculating a first power amount input into the workpiece (Wa, Wb) from the melting start time; and determining whether the first power amount has reached a first set value; and continuing the Joule heating until the first power amount reaches the first set value.

摘要： This invention aims to provide a resistance welding method capable of stabilizing quality or improving efficiency of resistance welding such as spot welding. This resistance welding method comprises a calculating step of calculating resistance ratio X of a second electric resistance value R2 of workpieces to be joined in residual heat after Joule heating stops to a first electric resistance value R1 of the workpieces immediately before the Joule heating stops or vice versa (R2/R1 or R1/R2); a determining step of determining whether the resistance ratio X is equal to or greater than a threshold value Xn, and a reheating step of carrying out the Joule heating again when the resistance ratio X is smaller than the threshold value Xn. Thereby at least part of a welding portion is melted and solidified to reliably form a nugget, and a stably resistance-welded member can be provided.

摘要： The present invention relates to a resistance welding method suitable for spot welding of a steel metal plate to which rust preventive treatment is applied through plating process and an aluminum metal plate, and is intended to realize high-quality welding by allowing high-density current to flow between a plated steel plate and an aluminum clad steel plate. An aluminum clad steel plate constituted by a steel layer having raised portions and an aluminum layer is interposed between a plated steel plate and an aluminum metal plate which are to be welded together. A predetermined welding current is supplied to an electrode from an alternating-current power supply. Since the supply path of the welding current is limited by the area of the raised portions, and since molten plating material produced when the plated layer is melted is received in pitch portions between the raised portions, the expansion of the current supply area is prevented. As a result of this, the interface between the plated steel plate and the aluminum clad steel plate is efficiently heated, whereby suitable nuggets are formed on both sides of the aluminum clad steel plate.

摘要： PURPOSE: To prevent the deformation and collapse of a building even when large load is applied from the outside at the tie of an earthquake, a strong wind, etc. CONSTITUTION: A reinforcing bearing device 19 is installed in such a manner that the front end section of a first inner shaft 21 and a coil spring 23 are inserted into an outer shaft 20 and the coil spring 23 is energized so that load in a certain extent is applied. When load is applied to the framework 15 of a building body 11 from the outside in the directions of the arrows, the building body 11 can be reinforced and borne under the state that the coil spring 23 is not deformed elastically when load is less than a fixed value. Since load more than the fixed value is permitted once even to the load and the coil spring 23 is deformed elastically, a function as the reinforcing bearing device can be held without damage. When load is reduced or removed, the elastic deformation of the coil spring 23 is restored, so that the deformation of the building body 11 can be restored.
