The presence of residual traces from the protective antioxidant coating, is a problematic issue since it causes a significant reduction in the welding seam strength. In this work, a solution based on a Laser Induced Breakdown Spectroscopy (LIBS) setup and a Support Vector Machines (SVMs) classifier to detect and discriminate antioxidant coating residues in the welding area without destroying the sample before the welding procedure is proposed. This system could be an interesting and fast tool to detect aluminium impurities.}, organization = {This work has been co-supported by the Spanish Government through the project TEC2007-67987-C02-01 and the grant AP2007-02230.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2010, vol. 7653, 765347}, publisher = {Fourth European Workshop on Optical Fibre Sensors, Oporto, 2010}, title = {Automatic classification of steel plates based on laser induced breakdown spectroscopy and support vector machines}, author = {Anabitarte García, Francisco and Mirapeix Serrano, Jesús María and Conde Portilla, Olga María and Cubillas de Cos, Ana María and Rodríguez Cobo, Luis and Galíndez Jamioy, Carlos Augusto and Cobo García, Adolfo}, }
