Platform welding with special technique CO2 carbon dioxide gas arc welding and auto submerged arc welding, precision measure the space positioning and advanced welding technique to ensure the platform space geometry-dimension and the rational distribution of weld stress.
FEATURS OF EXPERT – ORTHOTROPIC WEIGHBRIDGE:
We manufacture superior weighbridge structures employing globally accepted technology of Closed Orthotropic sections. The structures are manufactured by using closed orthotropic sections U beams. Each module is seal welded including top plate, side plates and contains orthotropic beams, as depicted in the GA drawings. This orthotropic geometry offers even load distribution throughout the structure. When there is concentrated loading on the structure there is minimum deflection and the load transfer is always vertical on the Load cells. This results in highly accurate Weighment. In bolted I beam based structures, the strength of bolts becomes very critical and sometimes leads to failure. As orthotropic structures are completely welded, the chance of structural failure is minimum.
These superior structures are designed using latest CAD and CAE procedures. Each structure is analyzed through our advanced structural software. These structures are also tested by using actual weights. Complete structure is fabricated using grade specific HT steel plates of Jindal/Essar and have much higher strength than the commercially available steel plates used by local fabricators. Compared to I beams available in the market which are re-rolled by many manufacturers, the thickness of the flange and web varies along the length of the beam leading to lower structural strength. However, Jindal/ Essar sheets are of consistent thickness. There is no chance of structure buckling, even on large loads, as these are closed sections.
Top plate thickness of 10mm and no splice joints or butt welds across the length of the beams. Quick and trouble-free installation by means of male/female construction. These structures are of considerably lower height compared to I beam based structures. This reduces the cost of civil construction, as the ramp size is reduced. In addition, Non-Destructive tests are used to test the strength of each fabricated structure in actual loaded condition. There is more corrosion possibility in I beam based structures as the beams are always exposed to environment wherein closed Orthotropic sections, there is no option of moisture Ingression as the complete structure is seal welded. This increases the life of the structure.
All welding is done by MIG and SAW technology using HT wires, which are compatible to the grade specific steel used in the structure fabrication. Structures are treated with Pre-Treatment chemical before painting to get rid of any scales/rust/oil/grease to ensure proper adhesion of primer and paint. Double layer of epoxy-based primer on all sides and epoxy based final paint (Oxford Blue shade) on the exposed surface to give a superior appearance.
