The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). In one embodiment, a tubular welding wire for joining steel workpieces via arc welding includes a steel sheath disposed around a core. The core includes iron powder, iron titanium powder, silico-manganese powder, iron silicon powder, iron sulfide, graphite, rare earth compound, and a frit. The frit includes a Group I or Group II compound, silicon dioxide, and titanium dioxide. The graphite and the frit together comprise less than 10% of the core by weight.

A method of manufacturing a connector and assembly of a cabling category and comprising two mating zones connected by an intermediate zone. Each of the zones is manufactured such that Near End Cross Talk (NEXT) resulting from transmission of the high frequency signal across each zone is below a specified amount chosen such that NEXT introduced by a high frequency signal transmission between via all the zones is below a level as specified for the cabling category.

The invention relates generally to welding and, more specifically, to welding wires for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW). In one embodiment, a tubular welding wire includes a sheath and a core. Further, the core includes a carbon source and an agglomerate having a Group I or Group II compound, silicon dioxide, and titanium dioxide. Additionally, the carbon source and the agglomerate together comprise less than 10% of the core by weight.

In a method for automated determination of the relative position (x/y/z) between a first hole (27) on a first microsystem component (11), which is preferably provided with a first channel (44) opening in the first hole (27), and at least one second hole (29) on a second microsystem component (12), which is preferably provided with a second channel (45) opening in the second hole (29), the two microsystem components (11, 12) lie in a liquid medium (41) at least in the region (25, 26) of the holes (27, 29). Under the supervision of a control device (15) controlled by a computer (22), the first and second microsystem components (11, 12) are displaced relative to one another into different relative positions (x/y/z). Electrical signals (37) are delivered to one of the two microsystem components (12, 12) and are recorded on the other of the two microsystem components (11, 12) as measurement values (38) which depend on the relative position of the two microsystem components (11, 12) with respect to one another. For different relative positions (x/y/z) between the two microsystem components (11, 12), measurement values (38) are determined, from which the relative position (xn/yn/zn) in which the two microsystem components (11, 12) are to be positioned with respect to one another in such a way that their holes (27, 29) are mutually aligned is ascertained in the control device (15) (FIG. 1).

An apparatus for maintaining cross-talk below a predetermined threshold is disclosed. The apparatus comprises cable mating zone for connecting each of a first set of contact pairs with a respective twisted pair of cable conductors, a device mating zone for connecting each of a second set of contact pairs with a respective pair of device contacts and an intermediate transmission zone for connecting each of the first set of contact pairs with a respective one of the second set of contact pairs. In each of the zones the cross talk noise is prevented from exceeding a predetermined cross talk noise threshold.

An apparatus for maintaining cross talk noise in each of a plurality of different zones in a twisted conductor pair cable connector below a predetermined cross-talk threshold. The apparatus includes a first connecting zone means for electrically connecting each of a first set of contact pairs with a respective first set of conductors. The apparatus also includes a second connecting zone means for electrically connecting each of a second set of contact pairs with a respective second set of conductors. The apparatus further includes intermediate transmission zone means for electrically connecting each of the first set of contact pairs with a respective one of the second set of contact pairs. A sum of the cross talk noise in the first connecting zone, the second connecting zone, and the intermediate transmission zone is below the predetermined cross talk noise threshold.
