SYSTEM FOR CONTROLLING WELDING PROCESS Russian patent published in 2004 - IPC

FIELD: welding, namely method and system for welding sections of pipelines or metallic plates one with another, possibly at laying pipelines in industrial plants, main pipelines, in ship building and other branches of industry. SUBSTANCE: at welding process electrode is moved near outer peripheral surface of tube sections. Welding parameters are registered and correlated relative to predetermined position. Position of formed bead of welded seam is determined by means of satellites of global positioning system. Control system detects different parameters of welding and also it detects global position of fused bead of welded seam. EFFECT: possibility for tracking welding process in any point of surface with high accuracy according to longitude and latitude. 40 cl, 2 dwg
