    Abstract: Methods for rating welding electrodes are presented, in which a standardized vertical-down double cap pass welding procedure is performed using a test electrode to create a test weld on a substantially flat workpiece surface, and the electrode is rated according to the amount of porosity in the test weld. A first vertical-down bead-on-plate welding operation is performed to create a substantially straight first weld bead on the workpiece surface, followed by a standardized moderate first slag removal operation to expose an upper portion of the first bead while leaving some slag along one or both longitudinal sides of the first weld bead. A standardized second vertical-down welding operation is then performed with the test electrode to cover the first weld, and another slag removal operation is used to remove any remaining slag. The test electrode is then rated according to the ratio of the number of visually discernable pores in the second weld bead divided by the test weld length.

    Abstract: A method of measuring the quality of a stick electrode used in forming the root bead of a pipe joint, which electrode has a wire diameter, a length substantially greater than 12 inches and an upper exposed rod head. The method comprises: preparing a standardized workpiece including two spaced plates with a groove between the plates having a set profile including a lower gap duplicating the root gap of the pipe joint and mounting the standardized workpiece on an incline with the groove facing upwardly where the incline is at a fixed known angle. Then a stick electrode of the type to be measured is selected and the rod head of the selected electrode is connected to the power lead of a DC power source set to a given output current correlated with the type of electrode. A root bead is laid in the gap from an upper start position on said workpiece by progressively filing the gap and then discontinuing the root bead welding at a lower end position when a given length of the electrode has been consumed; and, measuring the distance between the upper start position and the lower end position with the run out distance being indicative of a quality characteristic of the electrode. This method can be used to measure the run out per time instead of run out per electrode consumed length.

    Abstract: Stick welding electrode rating and ranking procedures are provided for determining stackability performance of stick electrodes for pipe welding operations. The rating technique involves performance of a standardized vertical down weld procedure using a stick electrode to form a weld bead in a test workpiece groove, in which the electrode is maintained during welding at a substantially constant angle relative to the workpiece groove. The electrode is advanced toward the groove at a slow speed to deposit molten metal in the groove while keeping the molten metal above the stick electrode end or the arc thereof without dripping. The resulting bead distance is measured along with the welding time and the stick electrode is rated according to a ratio of the weld time and the bead distance.

    Abstract: A facility for selecting and refining electrical parameters for processing a microelectronic workpiece in a processing chamber is described. The facility initially configures the electrical parameters in accordance with either a numerical of the processing chamber or experimental data derived from operating the actual processing chamber. After a workpiece is processed with the initial parameter configuration, the results are measured and a sensitivity matrix based upon the numerical model of the processing chamber is used to select new parameters that correct for any deficiencies measured in the processing of the first workpiece. These parameters are then used in processing a second workpiece, which may be similarly measured, and the results used to further refine the parameters.
