Abstract
Assembly technology plays a crucial role in the manufacturing process, influencing the efficiency, quality, cost and lead time of production. Assembly technology in the manufacturing process encompasses all techniques and methods used to join components into a finished product. Depending on the industry and specific requirements, assembly technologies can include a variety of techniques, from traditional mechanical joints to advanced bonding, welding or soldering methods. The paper analysed the feasibility of implementing alternative methods of joining blanks in the steel wheel manufacturing process. Testing was carried out to replace the wheel rim flash welding process with laser welding. The effectiveness of laser welding was evaluated by testing prepared butt jointed sheet samples. Tests were carried out on two types of structural steel: S355MC and DD11, which were subjected to flash welding and laser welding. The specimens were subjected to strength and macrographic tests to analyse their structure and mechanical properties. The results showed that laser welding for DD11 steel leads to an increase in tensile strength, while for S355MC steel this strength is reduced. Statistical analysis showed no significant differences between the assembly methods used and the steel types. Macrographic tests confirmed the presence of oxides and other characteristics of the assembly methods used. The results suggest that the choice of the appropriate joining method can have a significant impact on the quality and durability of the final product, which is crucial in the context of steel wheel production
