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 for weldbonding together metal sheets includes applying adhesive on the surface of a first sheet and placing a second sheet atop the first sheet. The sheets are heated at a selected location to a high temperature forming a metallic weld nugget between the first sheet and the second sheet. The adhesive may be a heat curable adhesive that is cured by the heat, or the adhesive may be heated at ambient temperatures. One or both of the sheets is then cooled in the area surrounding the selected location of heating so that the high temperature needed to created the metallic weld nugget is prevented from transferring so far beyond the selected location as to overheat the adhesive layer and thereby degrade the quality of the adhesive bond.

摘要： A method is provided for determining that the electrodes of an electric resistance welder are in need of replacement and dressing includes monitoring the rate at which the depth of the weld indentation caused by the electrode changes during the progressive wearing of the electrodes during the making of successive welds. The electrodes are then dressed when it is determined that the rate of change of the depth of the weld indentation formed by the electrodes has substantially leveled off to a stable depth of indentation.

摘要： A method of spot welding a sheet overlapped to a tube with a servomotor-driven electrode applying a clamping force to the sheet. Over a first clamping time interval, the clamping force is increased to a first force level, at which point a welding current is applied to weld the sheet and tube together for a welding time interval. The first force level is maintained for a second clamping time interval, after which the clamping force is reduced to a second force level over a third clamping time interval and is maintained for a fourth clamping time interval. The welding current is removed upon expiration of the welding time interval and the clamping force is simultaneously reduced over a fifth clamping time interval, after which the electrode is disengaged from the sheet. The reduction in clamping force during the welding cycle reduces cracking of the spot weld.
摘要翻译： 利用伺服电动机驱动的电极对与片材重叠的片材进行点焊以对片材施加夹紧力的方法。 在第一夹紧时间间隔内，夹紧力增加到第一力水平，此时施加焊接电流以在焊接时间间隔内将片和管焊接在一起。 第一力水平保持第二夹紧时间间隔，此后夹紧力在第三夹紧时间间隔内减小到第二力水平，并保持在第四夹紧时间间隔。 在焊接时间间隔期满后，焊接电流被去除，同时在第五夹持时间间隔内同时减少夹紧力，此后电极与片材脱离。 焊接循环期间夹紧力的降低减少了点焊开裂。

摘要： A joint assembly for joining first and second tubular members. The first member has flanges extending from walls of an end segment. The walls of the end segment define a receiving opening. The second member has walls and a protrusion having sides extending from the walls to an end of the protrusion. When the members are joined the protrusion is received in the opening of the end segment so that the sides of the protrusion are in facing engagement with the walls of the end segment and the flanges engage the walls of the second member. The members are secured together at some of the engaging surfaces. The protrusion reduces stress on the flanges and increases the mechanical strength of the assembly.

摘要： In attempting to reduce deformity when joining vehicle frame components, a riveting/brazing process has been proposed. This process includes joining tubular members, such as hydroformed parts, by cutting at least one flange into one end of a first body member, shaped in conformance with the surface of a second body member. Location holes are formed into each flange as well as into the surface of the second member in suitable alignment with each other. A brazing filler material is fixed into a side of the flange, usually within a pocket, intending to lie on the surface of the second member when the two structures are attached. The flange(s) are initially attached to the surface of the second member by means of a rivet to formed an actual vehicle body assembly. Heat is then applied to the assembly to form a brazed T-joint.

摘要： A method for repairing resistance spot welds formed between joined pieces of aluminum alloy sheet metal, such as vehicle body parts. The repair method includes resistance welding where an existing undersized spot weld is enlarged by applying electric current flow through the aluminum alloy sheets in the region around the existing defective weld. A pair of donut shaped electrodes may be used. Resistance to the current flow generates heat within the weld region. A new weld nugget is formed around the periphery of the existing weld and merges with it. The weld region is cooled and a repaired composite spot weld is formed.
