Joining of Tubular Parts by Electromagnetic Forming; Experimental Investigations
Materials Science Forum, 2014Electromagnetic forming is a high speed forming process, wherein the forming pressure is created by high energy density electromagnetic pulse. Besides direct shaping there are other application areas as well, so electromagnetic plastic forming is a potential field of creating joints between tube and rod-like components.

Joining Sheets to Tubular Profiles by Tube Forming
2012This chapter presents an innovative forming process for joining sheet panels to tubular profiles at room temperature. Finite element analysis and experimentation are utilized to understand the deformation mechanics of the process, to identify the operational feasibility window, and to discuss the capabilities across the useful range of working ...

Joining by laser shock forming: realization and acting pressures
Production Engineering, 2013The need to implement more functionality on the same space drives miniaturization and makes hybrid joints under various conditions also in the micro range necessary. Existing solutions often have restrictions due to the principle of joining. Thus, in this article a new high speed joining method for the micro range is presented, which is realized by a ...

Joining tubes to sheets by boss forming and upsetting
Journal of Materials Processing Technology, 2018Abstract This paper draws from new developments in boss forming of tubes to the proposal of a new joining by forming process for fixing tubes to sheets at room temperature. The process takes place in two stages and involves the production of an annular flange by partial compression of the tube wall thickness along the longitudinal direction and the ...

Potential of Joining Dissimilar Materials by Cold Formed Pin-Structures
Journal of Materials Processing Technology, 2020Abstract Joining dissimilar materials brings established joining techniques to their limits due to different thermal expansion, unequal stiffness/strength and chemical incompatibilities. The use of pin-structures has proven an appropriate strategy to join multi-material-systems in laboratory scale.

Joining similar and dissimilar material combinations by laser shock forming
Journal of Manufacturing Processes, 2020Abstract This paper verified the feasibility of joining similar and dissimilar material combinations by laser shock forming. Typical joining defects and failure modes during the deformation process were also discussed. Neck fracture often takes place in the lower foil, which was subjected to serious joint shearing effect from laser-induced shock wave

Forming Behavior during Joining by Laser Induced Shock Waves
Key Engineering Materials, 2015The ongoing trend of miniaturization makes hybrid joint also for the micro range necessary. Existing solutions often have restrictions due to the principle of joining. Therefore a new joining technology, which is realized by a plastic forming process based on TEA-CO2-laser induced shock waves, is used at BIAS.

Manufacturing of lightweight frame structures by innovative joining by forming processes
International Journal of Material Forming, 2009The majority of the materials used in modern lightweight frame structures are aluminium alloys. But some aluminium alloys, e.g. EN-AW6060, are not or hardly joinable using conventional joining techniques. In this case innovative joining methods like friction stir welding; joining by dieless hydroforming or by electromagnetic compression lead to good ...

Joining by Forming with a Flat Counter Tool - A New Way of Joining Magnesium Components
Materials Science Forum, 2007Joining by forming of magnesium alloys is restricted by the limited forming capability of magnesium at room temperature. For this reason heating of the parts to temperatures of 220 °C or more is required to form joints without cracks. State-of-the-art joining by forming methods (such as clinching or self-pierce riveting) are usually working with a ...
