Abstract: The invention relates to a fluidic system with a fluidic element and a transport device. The fluidic element comprises a basic body and a deformable membrane, the basic body comprising at least one first channel and at least one second channel for guiding a fluid, with at least one outlet being formed at one end of the first channel and at least one inlet being formed at one end of the second channel, and the membrane being connected to the basic body and covering at least the outlet of the first channel and the inlet of the second channel. The transport device comprises an actuator, the actuator being designed to deform the membrane such that a cavity is formed between the basic body and the membrane. The actuator comprises a magnetic shape memory alloy or consists thereof.

Abstract: The invention relates to a welding assembly for the permanent joining of a first tubular component with a second component along a two- or three-dimensional intersection curve, along which both components contact, comprising a securing assembly for detachably securely joining on a tubular end of the first component facing away from the intersection curve, a manipulator unit mounted directly or indirectly on the securing assembly such that it can pivot about a tube longitudinal axis assigned to the first component. The manipulator unit has a freely positionable manipulator end, with a welding tool attached to the freely positionable manipulator end. The securing assembly comprises a clamping module that can at least partially be introduced into the tubular end of the first component on the end side and in an axial manner.
