Fibre laser welded tube mill for USA YODER Manufacturing of Cleveland, Ohio, USA, has supplied a QVW-150 fibre laser welded tube mill for producing decorative stainless components up to 38mm (1½") diameter. accurately located and welded into the customer’s fabricating assembly. user to have one system instead of two TIG welding tube mills. It is claimed that the efficiency of this solution has enough available production capacity that the customer will be able to delay the need for additional tube making equipment by several years.

By de-coupling the finishing system after the cut-off, and utilising centreless brush technology, instead of an inline solution, the customer will be able to easily vary their type of polished or brushed finish, for the various products that they supply to different end markets. This can be done with the tube mill still in operation, and accumulating in process tubes, effectively maintaining continuous throughput of the overall system. This method of finishing, combined with the laser welding system, will enable the

The complete system consists of an entry end, forming machine, fibre laser welder with twin-spot welding head, sizing machine with integrated double cut shear system, brush de-burring system and a triple head centreless finishing system, all fully integrated for ease of operation. The mill also includes an ID marking system, so the tubing coming off the mill will be complete, ready to be

Yoder has provided similar systems, in recent years, for the chemical, oil and gas, and automotive markets, which require the integration of non-destructive testing and/or annealing equipment, depending on the specific application. For this latest tube mill, Yoder developed its new fibre-based fusion welding system with twin-spot welding optics. With these latest developments, laser welding is becoming more robust for the tube mill environment and less costly to operate when compared to CO 2 counterparts, as well as TIG/plasma welding. With the new fibre laser welding system there is no theoretical limit to tube diameter, and with this system the wall thickness capability has been practically expanded to 9.5mm (0.375"). Yoder designs and builds equipment, tooling and systems for metal forming, tube and pipe and heavy industrial material handling applications. The company can provide both engineered- to-order and off-the-shelf manufacturing solutions that increase production capacity and efficiency through integrated, streamlined processes, automation and faster machines.
