New welding profiles section H

FERMA has purchased and installed a semi-automatic equipment for manufacturing of welded steel H profiles, consisting of:

  • A system for pre-assembling of H sections from flat rolled sheet, through magnetized mechanisms for positioning and centering of flanges-web, with an integrated drive system roller to approach the feed table of pre-assembled sections.
  • A drive system roller for feeding the welding unit, with independent operation of the first drive system roller.
  • A central unit for pressing, centering and tractioning of sections, integrated to a SAW welding system, with two stationary torches and its with respective sources 1200A, fluxing by gravity and recovery system by vacuum turbines.
  • A complementary post-weld straightening of flanges, up to 40 mm thick.
  • A roller drive system for reception and evacuation of H profiles and its finished welds.

The capabilities of the equipment can be summarized as follows:

  • Maximum length: 15 m
  • Web height range: 150 to 2000 mm
  • Range flange width: 150-800 mm
  • Flange thickness range: 4 to 40 mm (with straightening) or 50 mm (no straightening).

This equipment allows integrating of a lots of manufacturing steps from various operating stations in a single unit, solving the needs in a smaller plan footprint, greater operational control, both production and quality, and making improvements and higher productivity in the manufacturing process, compared to a traditional line of welding.
