text: Abstract. Mechanical joints are traditionally analyzed through destructive
micrograph analysis, which may compromise internal geometry and morphology, as
evidenced by radial cracks in semi-tubular self-pierce riveting. In contrast,
industrial X-ray computed tomography (XCT) offers a non-destructive method for
component diagnosis, providing volumetric insights without damaging the sample
and enabling dimensional measurement. The DFG-funded Collaborative Research Center
TRR 285 is exploring XCT's application in assessing mechanical joinability across
various joining processes and materials, particularly in multi-material systems
like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material
compositions, leading to artifacts that complicate interface detection. This research
aims to validate XCT for joint investigations, yielding quantitative characteristics
that surpass those from traditional micrograph analysis.

text: Lightweight design by using low-density and load-adapted materials
can reduce the weight of vehicles and the emissions generated during operation.
However, the usage of different materials requires innovative joining technologies
with increased versatility. In this investigation, the focus is on describing
and characterising the failure behaviour of connections manufactured by an innovative
thermomechanical joining process with adaptable auxiliary joining elements in
single-lap tensile-shear tests. In order to analyse the failure development in
detail, the specimens are investigated using in-situ computed tomography (in-situ
CT). Here, the tensile-shear test is interrupted at points of interest and CT
scans are conducted under load. In addition, the interrupted in-situ testing procedure
is validated by comparing the loading behaviour with conventional continuous tensile-shear
tests. The results of the in-situ investigations of joints with varying material
combinations clearly describe the cause of failure, allowing conclusions towards
an improved joint design.

text: Abstract. Reducing the weight of vehicles can significantly lower
the energy or fuel consumed and thus the emissions during operation. One possibility
to assess this is the use of a property adapted multi-material systems containing
high strength steel, light metals like aluminium or magnesium and fibre reinforced
plastics. While expanding the number of materials used new challenges arise for
the production and furthermore the joining technology to manufacture the vehicle
made of the multi-material systems. One approach to overcome these challenges
is to use innovative and adaptable joining techniques which allows the manufacturing
of joints of different material combinations. Extensive research activities on
the two stage thermo-mechanical joining process with adaptable joining elements
was able to demonstrate the great potentials in terms of joining dissimilar materials
with good strength. The previously kinematic and path-based fabrication of auxiliary
joining elements is modified in this publication to a form-based approach with
a perspective of establishing an efficient process chain using easily and cheaply
available rods. Based on the new approach to produce the auxiliary joining elements,
it can be demonstrated that a reproducible production of the geometry is possible
for the investigated steel as well as aluminium material.

text: Abstract. Requirements of multi-material construction involve adjustments
to standard joining techniques. Especially the growing importance of integral
cast components poses additional engineering challenges for the industry. One
approach to achieve these goals are adaptable joining elements formed by friction
spinning. This approach uses friction-induced heat to form customisable joining
elements to join sheets for different boundary conditions, even for brittle cast
materials. It is possible to react immediately to adapt to the joining process
inline and reduce the amount of different joining elements. As the joining partner
serve casting plates of the aluminium casting alloy EN AC–AlSi9, which is processed
in the sand casting. Joining hypoeutectic AlSi alloys constitutes a challenge
because the brittle character of these cause cracks in the joint during conventional
mechanical joining. Furthermore, the friction-induced heat of the novel joining
process causes a finer microstructure in the hypoeutectic AlSi9 casting alloy.
In particular, the eutectic Si is more fine-grained, resulting in higher joint
ductility. This study indicates the joining suitability of a hypoeutectic aluminium
casting alloy in combination with adaptive manufactured additional joining elements.
Here, various mechanical and microstructural investigations validate the influence
of the thermomechanical joining technique. In conclusion, the potential of this
joining process is presented regarding the joinability of cast aluminium components.

text: Consistent lightweight construction in the area of vehicle manufacturing
requires the increased use of multi-material combinations. This, in turn, requires
an adaptation of standard joining techniques. In multi-material combinations,
the importance of integral cast components, in particular, is increasing and poses
additional technical challenges for the industry. One approach to solve these
challenges is adaptable joining elements manufactured by a thermomechanical forming
process. By applying an incremental and thermomechanical joining process, it is
possible to react immediately and adapt the joining process inline to reduce the
number of different joining elements. In the investigation described in this publication,
cast plates made of the cast aluminium alloy EN AC-AlSi9 serve as joining partners,
which are processed by sand casting. The joining process of hypoeutectic AlSi
alloys is challenging as their brittle character leads to cracks in the joint
during conventional mechanical joining. To solve this, the frictional heat of
the novel joining process applied can provide a finer microstructure in the hypoeutectic
AlSi9 cast alloy. In detail, its Si is finer-grained, resulting in higher ductility
of the joint. This study reveals the thermomechanical joining suitability of a
hypoeutectic cast aluminium alloy in combination with adaptively manufactured
auxiliary joining elements.

text: The demands on joining technology are constantly increasing due to
the consistent lightweight construction and the associated increasing material
mix. To meet these requirements, the adaptability of the joining processes must
be improved to be able to process different material combinations and to react
to challenges caused by deviations in the process chain. One example of a highly
adaptable process due to the two-step process sequence is thermomechanical joining
with Friction Spun Joint Connectors (FSJCs) that can be individually adapted to
the joint. In this paper, the potentials of the adaption in the two-stage joining
process with aluminium auxiliary joining elements are investigated. To this end,
it is first investigated whether a thermomechanical forming process can be used
to achieve a uniform and controlled manufacturing regarding the process variable
of the temperature as well as the geometry of the FSJC. Based on the successful
proof of the high and good repeatability in the FSJC manufacturing, possibilities,
and potentials for the targeted influencing of the process and FSJC geometry are
shown, based on an extensive variation of the process input variables (delivery
condition and thus mechanical properties of the raw parts as well as the process
parameters of rotational speed and feed rate). Here it can be shown that above
all, the feed rate of the final forming process has the strongest influence on
the process and thus also offers the strongest possibilities for influencing it.

text: Due to current global challenges regarding energy security as well as climate
change the importance of preserving the nature and all available resources is
steadily increasing. In order to achieve the energy-saving and climate targets,
it is not only necessary to develop new processes and processing possibilities,
but also to optimise known process chains with regard to energy and resource efficiency
in the area of production technology. Here, the recycling of supposed production
waste represents an opportunity to save energy. In addition to the conventional
and smelting metallurgical recycling process, extensive research activities have
therefore been carried out for alternative solid-state recycling processes. One
example is the friction-induced recycling process, which has been used in past
studies to demonstrate the energy- and resource-efficient production of semi-finished
products from aluminium scrap such as chips. In addition, properties like chemical
composition and strength can be adjusted locally and in terms of processing time.
This can be used to improve the versatility of further processing steps.

text: Mechanical joining technologies are increasingly used in multi-material lightweight
constructions and offer opportunities to create versatile joining processes due
to their low heat input, robustness to metallurgical incompatibilities and various
process variants. They can be categorised into technologies which require an auxiliary
joining element, or do not require an auxiliary joining element. A typical example
for a mechanical joining process with auxiliary joining element is self-piercing
riveting. A wide range of processes exist which are not requiring an auxiliary
joining element. This allows both point-shaped (e.g., by clinching) and line-shaped
(e.g., friction stir welding) joints to be produced. In order to achieve versatile
processes, challenges exist in particular in the creation of intervention possibilities
in the process and the understanding and handling of materials that are difficult
to join, such as fiber reinforced plastics (FRP) or high-strength metals. In addition,
predictive capability is required, which in particular requires accurate process
simulation. Finally, the processes must be measured non-destructively in order
to generate control variables in the process or to investigate the cause-effect
relationship. This paper covers the state of the art in scientific research concerning
mechanical joining and discusses future challenges on the way to versatile mechanical
joining processes.

text: The adaptive joining process employing friction-spun joint connectors
(FSJC) is a promising method for the realization of adaptable joints and thus
for lightweight construction. In addition to experimental investigations, numerical
studies are indispensable tools for its development. Therefore, this paper includes
an analysis of boundary conditions for the spatial discretization and mesh modeling
techniques, the material modeling, the contact and friction modeling, and the
thermal boundary conditions for the finite element (FE) modeling of this joining
process. For these investigations, two FE models corresponding to the two process
steps were set up and compared with the two related processes of friction stir
welding and friction drilling. Regarding the spatial discretization, the Lagrangian
approach is not sufficient to represent the deformation that occurs. The Johnson-Cook
model is well suited as a material model. The modeling of the contact detection
and friction are important research subjects. Coulomb’s law of friction is not
adequate to account for the complex friction phenomena of the adaptive joining
process. The thermal boundary conditions play a decisive role in heat generation
and thus in the material flow of the process. It is advisable to use temperature-dependent
parameters and to investigate in detail the influence of radiation in the entire
process.

text: Mechanical joining processes are an essential part of modern lightweight construction.
They permit materials of different types to be joined in a way that is suitable
for the loads involved. These processes reach their limits, however, as soon as
the boundary conditions change. In most cases, these elements are specially adapted
to the joining point and cannot be used universally. Changes require cost-intensive
adaptation of both the element and the process control, thus making production
more complex. This results in high costs due to the increased number of auxiliary
joining element variants required and reduces the economic efficiency of mechanical
joining. One approach to overcoming this issue is the use of adaptive auxiliary
joining elements formed by friction spinning. This article presents the current
state of research on pre-hole-free joining with adaptive joining elements. The
overall process chain is illustrated, explained and analyzed. Special attention
is paid to demonstrating the feasibility of pre-hole-free joining with adaptive
joining elements. The chosen mechanical parameters are subsequently listed. Finally,
a comprehensive outlook of the future development potential is derived.

text: Nowadays, the production of modern lightweight structures, like a body in
white structure requires a wide variety of mechanical joining processes. To fulfill
the various demands, mechanical joining processes and joining elements (JE) are
used. Very often, they are adapted to the application, which leads in turn to
a numerous of different variants, high costs, and loss of the process chain versatility.
To overcome this drawback, an innovative approach is the usage of individually
produced and task-adapted JE, the so-called friction spun joint connectors (FSJC).
These connectors can be modified in shape as well as in material properties. This
flexibility offers high potential for lightweight design but also increases the
necessary analytical effort regarding the forming process as well as the manufactured
joint's properties. Therefore, a new analysis strategy based on the Finite-Element-Method
(FEM) is proposed, which numerically determines the local load bearing capacity
within a given joint in order to identify the critical regions for load transfer.
The process of joining element manufacturing and the analysis strategy will be
described in detail and optimization results of the joints are shown. Numerical
results are discussed and possible recommendations for joint manufacturing are
derived.

text: Joints are an essential part of modern (lightweight) structures in a broad
variety of applications. The reason for this is the rapidly increasing number
of different material combinations needing to be joined in application areas like
the automotive industry. It is currently common to use numerous auxiliary or standardized
elements instead of individually adapted joining elements. This leads to a large
number of different joining elements per product and thus to high costs. An innovative
approach to overcoming this issue is the design, manufacture and setting of joint-specific
joining elements. A good candidate for the manufacture of adapted joining elements
of this type is the so-called friction spinning process. The joining elements
formed in this way can be specifically adapted to the application in question
in terms of both shape and mechanical properties. The part geometry required for
the properties of a given joint is formed using a universal forming tool. This
makes it possible to form a wide variety of sub geometries for the auxiliary joining
part as a function of the prevailing joint condition, using a single forming tool
and starting from the same semi-finished bar material. By applying different process
strategies for the rotational speed and feed rate during the forming operation,
the same part geometry can even be given different local mechanical properties.
The following contribution presents the results of ongoing research work and includes
the process concept, process properties, tooling and the results of experimental
investigations into the joining of two sheet metal parts with help of this new
joining process.
