FHWA challenged the North American steel industry to develop a cost-effective short span steel bridge with modular components which could be placed into the mainstream and meet the needs of todays bridge owners, including Accelerated Bridge Construction (ABC). Structural Steel WeldingStructural Steel Welding Semih Genculu, P.E. Arc welding requires striking a low-voltage, high-current arc between an electrode and the workpiece (base metal). The intense heat generated with this arc melts the base metal and allows the joining of two components. The characteristic of
JIS G3106 SM570 high strength steel plates are mainly for welding structure use. And material SM570 is a typical low alloy high strength steel material. SM570 welding structure steel is widely used in construction machinery, bridges, containers, vehicles, ships, power equipment and other structural parts.
