摘要： A system (10) and method for predicting weld quality in a stud welding system by measuring the displacement of a movable shaft (20) with respect to the gun body (12) during the weld process. A sensor (34) is positioned with respect to the welding system in order to produce a series of discrete signal values each indicative of this displacement. These values are plotted graphically and used to produce a weld "signature" which can be compared with signatures of welds of known quality to more accurately predict the quality of the current weld. Based on these weld signatures, various weld parameters including current, time and lift can then be adjusted until a consistent signature indicative of good weld quality is produced.

摘要： Welding apparatus for welding studs by a drop technique is provided. In this type of welding, a stud is held a predetermined distance above a workpiece with an electrical potential maintained therebetween. The stud is held in a chuck which in turn is associated with a plunger or ram. The stud, the chuck, and plunger are allowed to drop the predetermined distance to the workpiece at which time the stud becomes fused thereto. Weights can be applied to the plunger and the height of the stud above the workpiece can be varied to achieve a proper weld for a particular stud and a particular workpiece. The chuck, when in the initial welding position above the workpiece, is frequently too close to the workpiece to enable a new stud to be loaded easily, if at all. In accordance with the invention, means, and specifically a fluid-operated cylinder, is provided to raise the chuck and plunger to a position above the initial weld position to facilitate loading of a new stud. After loading, the plunger, chuck, and stud are lowered to the initial weld position at which time the weld can be effected in the usual manner.
