摘要： This invention provides a method of welding a cage and nut combination to a surface of a workpiece using a welding electrode as a holding and locating member for the cage and nut. The cage and nut are placed, upside-down, in a recess formed in the welding tip of a lower electrode which is positioned vertically with its tip up. The workpiece backed by an opposing welding electrode are positioned above the electrode holding the inverted cage. The inverted cage and workpiece are pressed together along a vertical axis and electrically welded. The lower electrode with its recess serves to accurately locate the inverted cage with its weld material projections for uniform welding contact with the surface of the workpiece for more efficient welding setup and an improved welded bond between the cage, retaining a nut, and the workpiece.

摘要： This invention provides a method of welding a flange nut to a workpiece surface using an improved design of a welding electrode. The electrode comprises a parts-receiving recess adapted to receive a stem portion of the nut, while maintaining a clearance between the recess and the stem. This clearance allows electrical current to be directed toward the flange portion of the nut. As a result, electrical contact between the workpiece and projections underlying the flange is greatly improved, thereby produce higher quality spot welds and increasing the life of the electrode tip.
摘要翻译：本发明提供一种使用焊接电极的改进设计将法兰螺母焊接到工件表面的方法。电极包括适于容纳螺母的杆部分的部件容纳凹部，同时保持凹部和杆之间的间隙。该间隙允许电流指向螺母的凸缘部分。结果，工件和凸缘下方的突起之间的电接触被大大改善，从而产生更高质量的点焊并且增加电极尖端的寿命。
