Abstract:
A method for joining studs to workpieces, in particular for the purpose of stud welding, comprising the steps of acquiring a distinguishing dimension of a stud to be joined by the application of a sensing element to the stud and through measurement of a travel distance of the sensing element as it is applied to the stud; and then joining the stud to a workpiece, if the dimension of the stud is within an allowable tolerance range, and the allowable tolerance range is adapted in dependence on the travel distance of the sensing element measured during a preceding method step.
Abstract:
A system is provided comprising a hardened stud body and an unhardened stud subunit coupled to the hardened stud body. The hardened stud body may comprise a first composition having by weight between 17% and 21% chromium, between 2.8% and 3.3% molybdenum, between 50% to 55% nickel, and between 4.75% and 5.5% niobium. The unhardened stud subunit may comprise a second composition having by weight between 20% and 23% chromium, between 8% and 10% molybdenum, at least 58% nickel, and between 3.15% and 4.15% niobium.
Abstract:
A fastening system for add-on parts to vehicles allows the add-on parts to be easily installed and removed. The fastening system includes a connection part that lies against the vehicle and the add-on part, which includes a base. The connection part is designed as a profiled element whose outer surface corresponds to the outer surface of a prism having a cross section of a regular polygon with at least one interior angle deviating from 90°. The base has a trapezoidal groove with opposing surfaces on opposing sides of a base surface that are arranged at an angle from each other. The two opposing surfaces lie flush with wiggle-free engagement against two lateral surfaces of the connection part. A hole extends through the base symmetrically with respect to the groove. A connecting element is inserted through an opening in the base and engages in a receptacle of the connection part.
Abstract:
A method for welding a weld-on element onto a component is proposed, comprising at least the step that, before the welding process, at least one of the parts being connected is wetted with a wetting agent over the full area and uniformly in layer thickness in a welding region.
