Claim 6:
7. An automated electric arc welding system, comprising:
a torch manipulator;
a welding torch extending from the torch manipulator;
a motion controller operatively connected to the torch manipulator to control movement of the welding torch along a weld path in a direction of a weld seam during a welding operation, and simultaneously weaving movements of the welding torch back and forth across the weld seam at a weave frequency and a weave period; and
a welding power supply operatively connected to the welding torch to control a welding waveform, and operatively connected to the motion controller for communication therewith, wherein the welding waveform includes a pulse current portion, and a low current portion having a lower current level than the pulse current portion, and wherein the welding power supply is configured to sample a plurality of weld parameters during a sampling period of the welding operation and form an analysis packet, and process the analysis packet to generate a weld quality score,
wherein the welding power supply receives torch position information and automatically adjusts the sampling period for forming the analysis packet based on the torch position information,
wherein the automated electric arc welding system includes through arc seam tracking logic that tracks the weld seam and calculates corrections to the weld path,
wherein the through arc seam tracking logic calculates the corrections to the weld path from welding current data classified as corresponding to the pulse current portion of the welding waveform, and welding current data classified as corresponding to the low current portion of the welding waveform, provided by the welding power supply, and
wherein when calculating the corrections to the weld path, the through arc seam tracking logic weighs said welding current data classified as corresponding to the pulse current portion of the welding waveform more heavily than said welding current data classified as corresponding to the low current portion of the welding waveform.
