Abstract

This paper aimed at applying Statistics Control Tools in a Transformer Industry sector. The quality characteristic selected to this study was the thickness of painting in several parts of the transformer (body, radiator, cover and support). After selecting the sector and the quality characteristic, a sheet of verification was used to collect the data. A new methodology was suggested to this production line. The methodology proposed has as base a Model presented by Soares (2001, p. 66), with necessary modifications to fit to the company under study. The data were analyzed by X and AM Control Graphs in several parts of the transformer. Many improvement plans resulted from the analysis and some of them in the statistics control. After achieving statistics control of the process, control limits were established and they will allow to monitor those processes from now on, as well as to calculate their capacity rates. In the analysis where the first out-of-control process was found, it will be necessary to continue the study of variability causes
