Implementación de un sistema de gestión de calidad en el proceso de soldadura aplicando las Normas AWS D1.1 y D8.8 en la Empresa Carrocera Carbuss Yaulema

Abstract

CAR-BUSS YAULEMA Company has detected problems in the welding procedures that have produced several faults, resulting in delays in the delivery of the bodies due to the need to reprocess the welds. In addition, this has generated problems in the quality of the structures and an increase in manufacturing costs. Therefore, the objective of this degree work focuses on establishing a quality management system for welding processes based on AWS (American Welding Society) standards, specifically AWS D1.1 and D8.8. Forms designed to ensure accurate monitoring of the quality process were implemented. These formats not as well as guarantee the integrity and complete strength of the joints in the structural elements that make up an interprovincial bus body, but also provide peace of mind to customers. This achievement was implemented through the execution of non-destructive and destructive tests that evaluated the appearance, strength and integrity of the weld seams in various joints. The introduction of the formats based on the aforementioned standards resulted in a substantial improvement in weld quality, with a 58.14% decrease in defects. This, in turn, led to a 20% reduction in weld times and a cost reduction of 46.62 per welded body. It is concluded that CAR-BUSS YAULEMA has been able to improve the quality of its car bodies by implementing a quality management system in its welding processes, which has resulted in a significant reduction of faults. In addition, significant improvements in both production times and associated costs have been identified.
