Abstract:
1. A method which may be used for remotely managing or controlling an electric arc welding shop utilizing at least one welding torch, said method comprising: a) feeding each torch at least one consumable wire; b) moving each consumable wire with a wire speed (V); c) subjecting each wire to an electrical current of intensity (I); d) determining, by means of a speed sensor, at least one wire speed value (V), wherein said wire speed value (V) is the average speed at which each wire feeds each torch over a given period (T); e) determining, by means of a current sensor, at least one current intensity value (I), wherein said current intensity value (I) is the average current which each wire is subjected to over said period (T); f) acquiring, by means of an of an acquisition means, at least one value of said wire speed value (V) and at least one value of said current intensity value (I); g) transmitting at least one of said wire speed value (V) or said current intensity value (I) to a data processing unit, wherein said data processing unit is removed from said speed sensor or said current sensor; h) determining, with said data processing unit, at least one productivity parameter, wherein said productivity parameter is determined from said transmitted wire speed value (V) or said transmitted current intensity value (I), and wherein said productivity parameter comprises at least one member selected from the group consisting of: i) remotely transmitting by means of a communication network, a value to a central remote control device, wherein said value comprises at least one member selected from the group consisting of j) defining manufacturing profiles for categories of workpieces welded in the shoo based on duty factor and deposition rate for the categories of workpieces depending on a generator used in the welding: k) organizing the profiles in the form of a library of models for use in scheduling work in the welding shop.
