US 2006/0124608 A1 · Process for short-time arc-welding and short-time arc-welding system

Abstract

A process and a system are proposed for short-time arc-welding elements, such as for example metal studs, on to components, such as for example metal sheets, wherein an element in the context of a welding operation is initially raised in relation to the component, a welding arc is formed between the element and the component, and the element is lowered again, the lifting height of the element in relation to the component being detected at least within a time segment between raising and lowering of the element. The initiation of the lowering operation and/or the lowering operation itself is controlled as a factor of the detected lifting height such that a previously specified total welding time is achieved.

Dependent claims

A welding system for welding an element to a component, the system comprising:

(a) a welding head operably initially moving the element in relation to the component and later returning the element;
(b) a detector operably detecting movement of the element;
(c) a controller operably controlling the welding head to return the element at a speed that is a factor of a detected movement;
and
(d) a power supply operably providing power for forming an arc for a specific time between the component and the element, wherein the specified time is controlled by the detected movement and the speed.
