Welding H-shaped steel, because the use of welding process to produce cross-section H-
shaped name, divided into submerged arc welding H-shaped steel, high-frequency welding H-
shaped steel. Submerged arc welding H-shaped steel adopts the process: steel plate --
automatic slitting -- assembly -- automatic submerged arc welding -- flaw detection -- flange
correction -- web correction -- end processing -- sand blasting -- rust removal -- spray
painting. Automatic submerged arc welding production line from cutting, assembly, welding are
all controlled by microcomputer, to ensure the production of H-shaped steel dimensional
accuracy, weld quality are up to national standards.
Advantage
It can be arbitrarily processed, designed and combined with the project, and can be manufactured with special specifications to meet the actual needs of special projects.
The specifications of H-shaped steel are economically designed, and its section torque, section coefficient, pressure resistance and load bearing are much higher than the hot rolled steel of the same unit weight.
