Apparatus and method for automatically aligning a welding device for butt welding workpieces |
摘要 |
Apparatus and method for aligning a welding device along the center of a gap defined by confronting edges of at least two workpieces to be joined, wherein relative motion between the welding device and the workpiece gap occurs along a longitudinal axis substantially parallel to the gap such that the proximal edges of the workpieces can be joined by forming a weld seam along the gap during the relative motion. The apparatus preferably includes an imaging system for determining the location of the gap center relative to a predetermined two dimensional coordinate system by monitoring an image of a vision area along the gap downstream of the welding zone. In a preferred embodiment, the imaging system is effectively isolated from the welding zone through use of a high magnification optics system, a shroud structure, an independent light source, and a vectored jet of inert gas supplied to the welding zone. |
