AUTOMATED WELDER MAKES MOST HULL T-FRAMES

Designed and manufactured by the Ogden Engineering V Corp of Schererville, Ind., an 8-year old newcomer to the automatic welding field, the T-Beam Fabricator is readily adaptable to producing large and small T's with webs from 6-in. to 14-ft. and up to 1 1/2-in. wide up to 2-in. thick in any combination. For example, Litton (formerly Ingalls Shipbuilding) is making special 4 by 6-in. T's from 3.4-in. plate for their graving dock. And Erie Marine routinely fabricates T-section transverse frames with 60-in. scalloped webs. Simple flame stripping of flat plate stock is all that is required to prepare the feed stock. Where the thickness of the material dictates it, flame-bevelling of the weld-joint edge is sufficient-no mechanical cutting or grinding is needed. In a typical installation flanges and web sections flame-stripped from flat plate feed directly from the cutting facilities by powered conveyor into a buffer storage area. A flange then moves laterally to the input conveyor. A web also moves laterally and automatically drops into vertical position atop the flange. The conveyor moves the mated pieces into the machine's end-alignment section, thence to the clamping and welding section where automatic submerged-arc welders join the parts. The welds achieved are the highest quality obtainable with this method, says Ogden, far superior in penetration and appearance to stick welding or even MIG welding.
