Product Description
H-shaped steel has two production methods: hot rolling forming and welding combined forming. Welding H-shaped steel is to cut strip steel with appropriate thickness into appropriate width, and weld the edges and waist together on a continuous welding unit. Welded H-shaped steel is named because the welding process is used to produce an H-shaped cross-section. It is divided into submerged arc welded 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.
