摘要： An apparatus includes a set of pre-welding electrodes including a shape-forming electrode having a contact face. The contact face has a shape-forming structure shaping a cross-section of a first segment of a first wire with a pre-welding shape upon compression of the contact face against the first segment. The pre-welding shape has a reentrance accommodating a second segment of a second wire to be welded to the first wire.

摘要： A passive current sensor includes a pair of electrically conductive busbars, a shunt resistor electrically connecting the busbars, and a support having a first pair of voltage drop measuring contacts. At least one of the voltage drop measuring contacts is attached to each of the busbars and forms a direct electrical contact between the at least one voltage drop measuring contact and the busbar.

摘要： A welding method includes providing a first connector having a first end, providing a second connector having a second end for being welded to the first end, overlapping the first end and the second end, applying a contactless heating to a central section of the first end and melting an end section of the first end facing the second connector, and cooling the first end and the second end to form a weld connecting the first connector and the second connector. The first connector and the second connector extend in opposite directions from the weld.
