Abstract
A system is disclosed for supplying particle material along a length of strip material which is then closed into a tube to provide welding wire or electrode. The strip material is moved longitudinally (while its flow rate is measured) and as it moves through a junction location, particle material is metered onto the strip, the flow rate of the particle material also being measured. The system compares the flow rates of the strip material and the particle material with a predetermined ratio to provide a control signal which controls the flow rate of the particle material accordingly. The strip material carrying the particle material is then closed to a tubular configuration to produce welding wire of improved consistency along its length. As disclosed, the system incorporates effective structures for measuring the flow of the strip material and for precisely metering the particle material.
