  • Publication number: 20200276548
    Abstract: A viscous material stirring apparatus includes a stirring member that rotates about a rotation axis and has a tip radially separated from the rotation axis, a rotary actuator that rotates the stirring member about the rotation axis, a moving mechanism that moves the stirring member, and a control device. The control device drives the moving mechanism to immerse the tip of the stirring member into an applied viscous material, drives the rotary actuator to rotate the stirring member around the rotation axis, and drives the moving mechanism to move the stirring member along a coating direction of the viscous material with the tip of the stirring member immersed in the viscous material.

  • Patent number: 9839973
    Abstract: A friction stir spot welding apparatus according to the present invention includes: a rotary tool; and a perpendicular-to-plane detector, which detects whether or not the rotary tool is positioned to be in a perpendicular-to-plane state relative to a joining target portion of workpieces. The perpendicular-to-plane detector measures distances to at least three measurement positions set around the joining target portion by means of, for example, position sensors. The measurement positions are set to be positioned at the vertices of a polygon on a reference plane to which forward and backward movement directions of the rotary tool are normal. The perpendicular-to-plane detector detects that the rotary tool is positioned to be in the perpendicular-to-plane state relative to the joining target portion of the workpieces if all the distances to the measurement positions are equal to each other.

  • Patent number: 7745758
    Abstract: To provide an arc start method in a consumable electrode type arc welding method capable of firmly executing arc start and capable of executing high quality high speed welding by restraining a welding defect from being brought about therefor, at a portion of a wire projected from a welding tip, a temperature of a front end portion of the wire is made to be at a temperature higher than a temperature of a portion thereof near the welding tip. The front end portion of the wire is preheated to 300° C. or higher, preferably, 450° C. or higher. The front end portion of the wire is preheated by generating arc for preheating. The preheating arc is generated in a spot-like shape at a position near a terminal end portion of a predetermined welding line by constituting a current lower than a welding current.

  • Publication number: 20060213888
    Abstract: There is provided a welding method and a welding equipment, in each of which it is possible to detect a weld abnormality, moreover it is possible to detect a generation position and a length of that abnormality, and further it is possible to perform a repair of a weld abnormality part. After a weld start signal has been inputted, a case where a welding current and a welding voltage, which have been detected by a welding current/voltage detection means, are outside set ranges is made the weld abnormality by an abnormality discrimination means. An abnormality generation time instant and an abnormality termination time instant are calculated with a start signal input timing being made a time axis reference by a time instant calculation means. An abnormality generation position and an abnormality terminus position are operated from data of the time instants and a robot position information by an operation means.

  • Publication number: 20060208029
    Abstract: To provide a wire aiming position control method and position control apparatus capable of accurately feeding a welding wire to an aiming position of a welded member regardless of a change in an amount of twisting the wire and to provide a wire aiming position control method and position control apparatus capable of accurately ensuring an aiming position of a torch and capable of ensuring stable welding quality even in thin plate welding, an intersection K1 of a linear line L1 connecting a center of a tip 10 and a wire front end and an extension plane L2 including an imaginary aiming position K disposed at a predetermined position is calculated. A wire displacement C constituting a distance between the intersection K1 and the imaginary aiming position K is calculated. At least either one of a welding wire W and a welded member 14 is corrected along the extension plane L2 by an amount of the wire displacement C.
