METHOD OF AND PLANT FOR CONTINUOUS MANUFACTURE OF TUBULAR WIRE SKELETON Russian patent published in 2008 - IPC B23K11/06 B23K101/24 B29D23/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in production of carrying members of filters, fittings of metal-plastic pipes, spatial reinforcement members of reinforced concrete articles, etc. According to proposed method, wire spiral is uniformly wound at preset pitch on longitudinal wire members arranged uniformly over circumference of mandrel and is welded by roller electrode with crossed over longitudinal wire members in process of winding. Position of electrodes is adjusted by opposite longitudinal displacement. Speed of displacement is adjusted continuously either manually, or automatically. Automatic adjustment is done taking into account readings of support electrode wear sensor connected through feedback with electrode shifting mechanism.

EFFECT: provision of stability of diameter over length of skeleton at its manufacture, reduced labor input, provision of high accuracy of skeleton diameter, stable strength of welded joints over length of skeleton.
