Abstract: An automatic material changing and welding system for stamping materials includes a welding transfer sliding table and a welding platform. The automatic material changing device further includes a feeding system. The feeding system includes a double-head uncoiling machine, an automatic feeding machine and a flattening machine. The automatic material changing device is used for automatic feeding for a stamping machine. The system triggers a material changing signal through a sensor to control and integrate the welding transfer sliding table and the welding platform to act to execute a welding procedure, so that the stamping materials are in welding connection with new and old coiled materials through a welding connection plate to realize continuous production operation of an automated stamping production line.

Abstract: A pressing unit presses a plurality of electrodes housed in a housing path in a housing case toward an electrode outlet port. When a lever member swings to one side, a distal end of the lever member comes to be in a first position in which the lever member covers a part of the electrode outlet port. When the lever member swings to the other side, the lever member comes to be in a second position in which the distal end exposes the electrode outlet port. A first coil spring is disposed between a proximal end of the lever member and a first side surface portion of the housing case, and biases the proximal end of the lever member to a direction away from the housing case.

Abstract: An electric resistance welded steel pipe having an identifiable seam portion and a method for manufacturing the same. The electric resistance welded steel pipe includes a steel pipe portion with a seam portion, which is formed by electric resistance welding, and a coating portion of zinc phosphate. The coating portion covers at least an outer surface side of the steel pipe portion. A part of the coating portion that is immediately above the seam portion forms a color difference portion that has a width W along a pipe circumferential direction of greater than or equal to 0.1 times a wall thickness of the pipe and less than or equal to the wall thickness of the pipe. The color difference portion has a visually identifiable color difference from the other parts of the coating portion.

Abstract: As a correction amount is acquired a deviation between a first rotational angle of a servo motor when a reference movable electrode is brought into contact with a reference opposite electrode and a second rotational angle of the motor when the reference movable electrodes pushes in the reference opposite electrode with a predetermined pressing force; and a third rotational angle of the servo motor when a movable electrode to be measured pushes in an opposite electrode to be measured with the same pressing force is corrected based on the correction amount.

Abstract: An electric spot welding head for a multi-axis industrial robot that has a compact configuration, particularly in a longitudinal direction that goes from the end of the head for the attachment to the robot wrist towards the welding electrodes. This result is achieved primarily by the fact that the electrical transformer mounted on the head has its output connected to the electrode-holding arms arranged, respectively, on a front wall of the body of the transformer and on an end wall of the body of the transformer, for the connection to the electrode-holding arms of the head. The structure of the welding head is completely covered by a casing having a rear opening for connection to the robot wrist and a front opening from which the electrode arms of the welding head protrude.
