What are the advantages of welding H-shaped steel?

It is named because the welding process is used to make the cross-section into an H shape. It is divided into submerged arc welding H-shaped steel and high-frequency welded H-shaped steel. The process of submerged arc welding H-shaped steel is: steel plate - automatic striping - assembly - automatic submerged arc welding - flaw detection - flange correction - web correction - end face processing - sand blasting and rust removal - painting . The fully automatic submerged arc welding production line's cutting, assembly and welding are all controlled by microcomputers to ensure that the dimensional accuracy of the H-shaped steel produced and the quality of the welds meet national standards. Adopt GB50205-2001 standard. High-frequency welding of H-shaped steel relies on high-frequency current to partially melt and weld the metal itself, without the need for welding wire or flux. It can be produced continuously at high speed, with high output and easy to realize mechanization and automation. The same cross-section has excellent cross-sectional properties.
It can be processed, designed and combined at will according to the project, and special specifications can be manufactured to meet the actual needs of special projects. H-shaped steel specifications have been economically designed. Its section moment, section coefficient, pressure resistance and load-bearing capacity are much higher than those of the same unit.
