Safety Issues Concerning Robotic Welding of Large Elements

Abstract

Robotic welding of large elements poses significant difficulties regarding the technological process, robot functions and the safety of the operator and other people. The health risks involved arise out of the weight of elements, high heat capacity, harmful gases and fumes. Under the Eureka project, the PIAP team is developing a model of a robotized cell designed mainly for welding large elements. Occupational safety is of paramount importance and hence is a constructive discussion on occupational health risk factors. The replacement of human workers with robots on assembly nests, especially in SMEs, eliminates the exposure of workers to hazard, but is focused on a reduction in employment rather than in significant improvements to the workplace. The paper analyzes and discusses European safety regulations contained in the European directives and applicable EN standards. Appropriate safety programs of diverse welding processes and materials to be implemented by designers and suppliers of robotic welding stations and lines, as well as by the users thereof, will be indicated.
