摘要： A method for forming an electrical resistance weld between a metal tube and a metal sheet is disclosed. In the method, a plurality of generally circular protrusions having generally triangular cross sections is formed upon the sheet. Thereafter, electrodes are utilized to flex the tube, while an electrical current is generated for electric resistance welding the sheet to the tube.

摘要： An RFID tag system and method. An RFID tag is encapsulated within a protective material and formed as a ball. The RFID ball is then mixed with a material that is to be deposited on a particular work piece, such as a coating being deposited on a piece of sheet metal. The RFID ball can later be read when the work piece is in the production environment using a suitable RFID reader. In this manner, the RFID ball forms a permanent part of the work piece and is able to be interrogated at any occasion during the assembly of a product.

摘要： Method and apparatus for detecting unacceptable misalignment of welding electrodes. An electrode-alignment station is positioned adjacent a welding station. A robot controls the movement of the electrodes, and occasionally moves the electrodes out of the welding station and into an electrode-alignment station. At the electrode-alignment station, the electrodes are closed on a fixture that transfers electrode-misalignment into movement of a plate that triggers an alarm if the misalignment is greater than a prescribed amount.

摘要： A method and apparatus for measuring the contact resistance at electrode-to-workpiece and workpiece-to-workpiece interfaces for spot welding simulations. A constant compressive load is applied through electrodes and workpieces to simulate a load applied during an actual resistance spot welding process. A discharging current circuit applies an initial high current of the order of 1.2 KA to electrodes and workpieces to break down contaminant films on surfaces of the workpieces. A relatively small constant current of about 2A is then applied to the electrodes and workpieces and the voltage across and the current flow through the electrodes and workpieces are measured. The contact resistance is determined from the measured voltage and current.
