Abstract (en)

[origin: WO2020173685A1] The invention relates to an apparatus (1) for producing, for concrete components, a reinforcement construction (5) welded together from at least two wires (2, 3, 4), particularly for producing a lattice girder (5) welded together from at least one bottom chord (2), at least one top chord (3) and at least one diagonal chord (4), the apparatus comprising at least one welding apparatus (6, 7, 8) for welding the at least two wires (2, 3, 4) at an intersection point (30), wherein the apparatus (1) comprises at least one measurement apparatus (9, 10) for measuring at least one welding parameter (11) during the welding of the at least two wires (2, 3, 4) at the intersection point (30), at least one open-loop and/or closed-loop control device (12) and at least one measurement value transfer apparatus (13, 14, 15), wherein the at least one measurement transfer apparatus (13, 14, 15) is designed to transmit the measurement values (16) of the at least one welding parameter (11), determined by the at least one measurement apparatus (9, 10), to the at least one open-loop and/or closed-loop control device (12), and wherein the at least one open-loop and/or closed-loop control device (12) is designed to compare the measurement values (16) of the at least one welding parameter (11) determined by the at least one measurement apparatus (9, 10) during the welding of the at least two wires (2, 3, 4) and/or values (17) of at least one derived parameter (36) calculated therefrom, to at least one reference value (18, 19, 27) for the reinforcement construction (5) to be produced, wherein the at least one open-loop and/or closed-loop control device (12) is designed to classify the welding of the at least two wires (2, 3, 4) at the intersection point (30) as admissible or inadmissible based on the result of the comparison of the measurement values (16) and/or the values (17) calculated therefrom to the at least one reference value (18, 19, 27), wherein the at least one measurement apparatus (9, 10) is designed to measure the at least one welding parameter (11) for a plurality of time values (22) during the welding, and the at least one open-loop and/or closed-loop control device (12) is designed to form a measurement function (23) by associating each of the measurement values (16) of the at least one welding parameter (11) to each of the time values (22) and to compare said measurement function to at least one reference function (24, 25, 26).
