is required, the sub-plates are disconnected from the universals using a hydraulically operated disconnect. The sub-plates can then be removed with an overhead crane. When the second set of sub-plates are installed, the sub-plates are moved into position and located to the universals using the same hydraulic system. The weld box was designed with interchangeable back plates to lessen weld roll change time. Electric motors on the weld box allow roll adjustments to be made from the operator’s station instead of manually. A T&H Lemont seam orientation stand is included in the mill to ensure that the weld seam is maintained at top dead centre for round tubes. However, if the specification for squares and rectangles calls for the weld seam to be moved from top dead centre, the unit will give the customer the flexibility to move the

T&H Lemont has commissioned a Model WU35M-11 high frequency welded mechanical tube mill for a repeat North American customer. T&H Lemont was chosen for the project based on the successful installation and commissioning of other mills for the customer over the last 20 years. The WU35M tube mill has a tube size range from 2" OD to 6.625" round tube at yields up to 65,000 psi material yield. The gauge range for these sizes is from 0.09" to 0.25". The mill is also designed to form and weld 5.75" OD x 0.375" wall tubing for a custom application. The mill will produce at speeds up to 300fpm. For reduced changeover times, the mill includes a number of quick-change features. The design of the mill includes a permanent third stand to minimise the time required for sub-plate removal and replacement. When a changeover
