Abstract: A method of controlling the quality of a product having a weld seam extending longitudinally thereof, the seam being progressively produced by a welding arc generated across adjacent edges of product stock as the stock travels past a welding station, and as the edges are forced together at a location downstream from the welding station. The method includes the steps of continuously measuring a plurality of critical welding parameters as the seam is being formed, and identifying for rejection the lengths of the product welded when any one or group of the welding parameters deviate from limits predetermined for the parameters. By this method confidence levels of 99.95 percent, soundly welded product are obtained.
