Estudio de defectos de soldadura a partir de modelado tridimensional por escaneo láser

Abstract

This work presents the metrological analysis of the three-dimensional model obtained by laser scanning technology applied to a metal plate that has surface defects resulting from poor welding application. In this evaluation, defects such as splashes, over-coverage and excess material were taken into account. . melted, applying for this purpose standards such as API 1104 and ISO 5817, while for the study of welding defects, use is made of standards such as DIN 8524 and BPVC chapter 9, from which recommendations are obtained to improve said technique and procedures for the subsequent treatment of affected surfaces. Emphasis is also placed on the application of laser scanning technology and the possibility of extending its use in the evaluation of welding processes such as those indicated in ISO 17637 that involve methods ranging from visual inspection to non-destructive testing is proposed.
