Systems and methods are used to determine a defined fastener for fastening two parts together at an assembly fastener location. The defined fastener comprises fastener components selected from a plurality of different fastener components available for use in an assembled fastener. The fastener components of the defined fastener may be selected based on criteria defining characteristics of an assembly stackup including the two parts and the assembled defined fastener. Dimensions of the two parts at respective fastener locations forming the assembly fastener location may be used to determine a part stackup dimension for the assembled fastener at the assembly fastener location.

Some examples of the present disclosure relate to welding systems that provide cooling gas flow to contact tips. The contact tip may be retained within a neck and nozzle assembly of a welding torch that receives gas, such as shielding gas, for example, from the welding system. A tip retention-device and gas diffuser may cooperate to retain the contact tip within the neck and nozzle assembly. The gas diffuser may have axial gas channels configured to direct the shielding gas over and/or across a rear portion of the contact tip seated within the gas diffuser. The tip retention device may have gas channels configured to guide gas flow from the gas diffuser over and/or across a forward portion of the contact tip. The gas flow may help to cool the contact tip before, during, and/or after welding, which may extend the life of the contact tip.

A system and method for threading a torque tube through an opening within a U-bolt and module rail device is described. The system and method provide aligned horizontal movement of the torque tube across an assembly frame resulting in the torque tube being threaded through a plurality of U-bolt and module rail devices. After the threading process is complete, the threaded U-bolt and module rail devices are secured in place on the torque tube to allow coupling of solar panels to the module rails.

An electronic-component mounting device is provided with: a gripping portion for holding an electronic component having a lead wire; a conveyance portion for conveying the electronic component gripped by the gripping portion onto a substrate to which an insertion hole is provided; and a swinging portion for swinging the electronic component and the substrate relative to each other, the electronic component being released on the substrate from gripping by the gripping portion.

Sucker rods include end fittings having an outer wedge portion proximate to an open end, an inner wedge portion proximate to a closed end, and an intermediate wedge portion between the outer and inner wedges. Each wedge includes a leading edge, a trailing edge, and an angle between the leading and trailing edges. The triangular configuration, length of the leading edge, the length of the trailing edge, and size of the angle in each wedge portion cause distribution of force, such that compressive forces distributed to the rod proximate the closed end exceed compressive forces distributed to the rod proximate the open end. An automated installation procedure installs the end fitting through the use of multiple chucks, positioned by servo motors along a fitting table.
