Abstract

To build the car body parts of today's cars, materials of higher strength are used on an ever-wider scale. They are, for example, boron-containing steels, which are highly resistant to special thermo-mechanical processing, coated with AlSi; e.g. USIBOR 22MnB5 type materials. For the final assembly of all body mounting components, it is necessary to apply different types of joining stud elements. One of the possibilities of making joinings between sheets and fastening elements - studs is the technology of short-circuit stud welding.This article aims to evaluate the influence of welding parameters of steel studs on high-strength steel sheet type USIBOR 22MnB5 with AlSi coating on selected mechanical properties of joints.
