Abstract: Texture for breaking oxide layers on an electrode and a tool applying texture to an electrode is disclosed. The tool may be used during a pattern creating process where the texture is applied to the electrode tip, or may be used during a re-conditioning process where a new texture is applied to a deteriorated electrode tip. The textured surface may include a pattern of raised or depressed features (teeth, knurls, protrusions, depressions, ridges, asperities, cross-hatches, parallel or non-parallel lines, star shapes, triangles, hexagons, etc.). The tool includes a plate having an upper side and a lower side, and a texture surface is arranged on one or both of the upper and lower sides of the tool. The tool's texture surface may include various asperities or patterns, which are imprinted onto the electrode tips by squeezing the electrodes against the upper and lower sides of the tool.

Abstract: A welding installation with a calibration tool is provided in a device for producing container shells. The force exerted by the container shells on the calibration tool is measured and evaluated as information for the overlapping width of the respective container shell. This allows adjusting the calibration tool during configuration of the device and allows the removal of container shells welded with too large or too small overlapping during production of container shells.

Abstract: A bolt feeder is for supplying a bolt to a resistance welding machine that performs resistance-welding of a workpiece and the bolt using a lower electrode. The bolt feeder comprises a holding unit configured to receive the bolt fed by a bolt feeding unit with a head located above a shaft, a moving unit configured to move the holding unit, and a pusher member configured to protrude from and retract into a tip end of the upper electrode. The bolt includes a projection on a top surface of the head which is opposite to a surface provided with the shaft. The lower electrode includes an insertion hole into which the shaft is inserted. The shaft is inserted into the insertion hole by the pusher member protruding from the tip end of the upper electrode and pushes an area of the top surface where the projection is absent.

Abstract: A component supply device is configured to feed a component having a through hole to a target position. The component supply includes: a rod including at its distal end a holding portion to be inserted into the through hole; an actuator; a valve mounted on the rod; and a fixing portion by which the valve that advances with the rod passes. The rod includes a gas outlet located in an outer periphery of the holding portion and configured to blow gas rearward, and a gas passage extending inside the rod and configured to send gas supplied from a gas source to the gas outlet. The valve includes a push switch configured to be switched between an advanced attitude and a withdrawn attitude, and a biasing unit configured to bias the push switch to the withdrawn attitude. The fixing portion includes a pressing wall portion facing the push switch.

Abstract: A method for monitoring welding of an electric resistance welded steel pipe of the present invention includes: an image acquisition step in which, when an electric resistance welded steel pipe is welded, a V-convergence portion including an edge detection area and a V-convergence point, and a welding portion including a position where a molten steel starts to be discharged from an inside of a wall thickness and a bead, are imaged to obtain a captured image; a determination information acquisition step in which the captured image is image-processed, and a molten length from the V-convergence point to the position where the molten steel starts to be discharged or a molten width of the welding portion or a combination thereof is acquired as a determination information; and a determining step in which it is determined whether a cold welding has occurred by comparing the determination information with a determination threshold value set in advance for each wall thickness of the electric resistance welded steel pipe.

Abstract: A multi-tiered weld program that is effective in resistance spot welding of dissimilar materials is disclosed. The process is repeatable across a multitude of grades/thicknesses, and number of sheets of conductive materials, and is possible to perform with traditional weld tooling and electrodes. Different size/different material/different contact face geometries weld surfaces are used to balance thermal properties of the materials, and the process is designed to create a small, consistent Intermetallic Compound (IMC) that is effective in holding two different conductive materials together with a high level of strength that is suitable for industrial mass production. The multi-tiered resistance spot weld process uniformly preheats, welds, and cools the samples to control the formation of the IMC that is formed therein.
