摘要： Exemplary embodiments 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： 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 start start time and a resulting nugget. The resistance welding method includes: pressing an electrode against a workpiece; inputting power to the workpiece through the electrode to subject the workpiece 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 starts to melt when subjected to Joule heating; calculating a first power amount input into the workpiece 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： In a butt-welded joint structure in which the entire peripheral edge or both end sides of the abutting surface are welded, first and second cutouts for determining insufficient penetration and determining excessive penetration are formed. After butt welding, ultrasound is beamed onto each of the first and second cutouts of the joint structure and the reflected wave is measured. The acceptability of the weld penetration depth is thus determined on the basis of both of the reflected waves. This determination is performed on the entire peripheral edge portion or both end side portions of the butted face between the welded materials, and the acceptability of the weld penetration depth of the corresponding portions is inspected.

摘要： A first member is adapted to measure an electrocardiogram of a patient. A second member is adapted to measure a peripheral pulse wave of the patient. A first calculator calculates a pulse wave propagation time (PWTT) and a heart rate (HR) of the patient based on the electrocardiogram and the peripheral pulse wave. A second calculator calculates a cardiac output (CO) of the patient with an equation of CO=(αK·PWTT+βK)·HR, where α, β and K are coefficients inherent to the patient.
