Identification of threats during the bodywork and paint repair process

Abstract

Body repairs are often based not so much on procedures as on the experience of the people who perform these repairs. The problem is that heat repairs change the internal structure of the vehicle's skin. When obtaining homologation, manufacturers must prove the specific strength of the materials during crash tests. During a bodywork repair, these parameters may change, and after the repair, there is no obligation to check the strength parameters of a specific element or system. By interfering with the structure, we cannot be sure that we still maintain an appropriate level of security. Therefore, during further tests, together with a team from the Bydgoszcz University of Technology, we plan to check the strength parameters of the vehicle's skin after repair. And what impact on the structure of the material is the duration of individual stages of sheet metal work, the intensity of the current and the temperature to which the material is heated in order to optimize the parameters and increase the level of safety of users.
