Leading the way with HF welded engineered structural sections

ALPHA Metall GmbH & Co KG develops scarfing systems for removing the inside bead from longitudinal welded steel tubes. Alpha Metall has now introduced the fifth generation of ID scarfing mandrels. Alpha Metall premium carbide cutting rings can be supplied with special geometry for meeting the specific requirements of tube manufacturers and processors in hard steel. The Alpha Metall multi-station strip edge shaving machine is recommended to avoid welding faults in galvanised or aluminised steel tubes, cleaning 2mm from the top and bottom strip edges. The oscillating tube weld bead outside scarfing machine can be adapted to different diameters. Alpha Metall is present, or has a representative, in all countries.

IN recent years Thermatool has continued to play an active part in the metal building and construction sectors worldwide, gaining a strong reputation as a leading supplier of hollow structural section HF welding technology. The latest range of Thermatool solid-state, high frequency contact welders have become central to the manufacture of high quality engineered structural sections. Engineered structural sections such as I, H, T and other asymmetrical shapes can be welded continuously on a specially designed HF welding mill. Recent advances in steel chemistry with the advent of advanced high strength steels and excellent HF weld quality has increased the demand for engineered structural sections. Thermatool has uniquely advanced a proven range of HAZControl Technology welders that offer custom I-Beam producers excellent weld quality in materials not previously available in structural sections. Thermatool solid-state, high frequency

contact welding technology will precision heat and subsequently forge weld engineered structural sections at high line speeds with maximum precision, requiring no secondary re-straightening prior to shipment. To satisfy a growing market Thermatool welding technology has brought about the opportunity to produce a virtually unlimited selection of custom beam sections that offer improved load bearing performance with a lighter weight product. The results can be seen in the structure of the Birds Nest Stadium in Beijing, on board the latest generation of ocean super-tankers and at many new sports stadiums around the world.
