Implementación de una línea semiautomatizada de ensamble de vigas IPE para estructuras metálicas, en la mecánica industrial Quinmetal ubicada en la ciudad de Riobamba

Abstract

In QuinMetal Industrial Mechanics, an automated system was implemented for the Metal Inert Gas (MIG) welding process in the semi-automated assembly line of IPE beams. Previously, the assembly was performed manually, which was labor-intensive and prone to human errors. Introducing a Cartesian robot for automatic welding yielded favorable results, reducing the operation time by 136 minutes compared to manual welding. The research was based on logical and general reasoning, applying steps and procedures that optimized the process performance. Both production and the quality of the weld bead were improved. Additionally, Computer-Aided Design (CAD) design and static analysis of the automated system supports were conducted using the modulus of elasticity of A36 steel. The values obtained were below the yield strength of 25 MPa, and the displacements were considered negligible, allowing for the construction of the base. Implementing the semi-automated IPE beam assembly system had an important impact in Riobamba, where few companies perform similar work. The assimilation of a Cartesian robot for welding became a promising alternative, reducing reliance on intensive labor, eliminating long-term illnesses caused by exposure to welding gases and arcs, and decreasing workplace accidents. Furthermore, production and delivery times were optimized, significantly improving the quality of the weld bead.
