Så är sommaren över (även om den här i Karlskrona dröjer sig kvar och skapar underbara dagar och kvällar långt in i September), och det är dags att hälsa en ny kull, eller “cohort” välkomna till BTH! Vi har ca 80 nya studenter och det är en mix av maskinteknik och marin teknik (civilingenjör-produktutveckling-marin teknik/högskoleingenjör) […]

The PREDICT project have been running between 2020-2024, and was recently closed. Project leader Shafiqul Islam shares the project summary in this video. PREDICT has generated results and tools that are used to increase reliability of failure prediction of sheet metal forming simulation in finite element models (FE-model). The work in this project was focused […]

Scrap-based production of Steel using Electric Arc Furnace (EAF) with possibility of 100 % scrap charges, offers a Circular Economy based solution to reduce CO2 emissions when compared to the integrated Blast Furnace (BF) + Basic Oxygen Furnace (BOF) route (1.81 tCO2/tsteel for BOF vs 0.23tCO2/tsteel for EAF). However, EAF production of sheet steel is […]

The ADSUP project further expands on the impact of the CAMBER project, reducing the lead time of tool tryout in the material forming industry. The tool cost for the manufacturing of components, i.e. in the automotive sector, has a huge impact on the total manufacturing cost, why a reduction of the effort and lead time […]

Abstract In this paper, dissimilar aluminum (Al) and copper (Cu) metals were joined together using ultrasonic metal welding (USMW), a solid-state welding technology. From the perspective of increasing the base metal welding contact area, the Cu/Al mating surface was innovatively prepared and ultrasonically welded. A comprehensive analysis was carried out on the forming quality, welding […]

Abstract During the running production of automotive body components drifts in theprocess window is seen causing problems with non-conforming parts. Up until now, these driftshave been counter-acted based on the knowledge and experience of the press line operators.This experience-based process control will however become more troublesome in the future asrecycled material grades will undoubtedly present […]

Abstract In the industrial production process, unsupervised visual inspection methods have obvious advantages over supervised visual inspection methods due to the scarcity of defect samples, annotation costs and the uncertainty of defect generation. Currently, unsupervised defect detection and localization methods have demonstrated significant improvements in detection accuracy to find numerous applications in industrial inspection. Nonetheless, […]

Abstract Ultrasound welding technology is widely applied in the field of industrial manufacturing. In complex working conditions, various factors such as welding parameters, equipment conditions and operational techniques contribute to the formation of diverse and unpredictable line defects during the welding process. These defects exhibit characteristics such as varied shapes, random positions, and diverse types. […]
