The application of steel structure is very extensive. As one of the main building structures, it is often used in large workshops, venues, etc. The steel structure material needs to be preheated during processing. Preheating can reduce the restraint of the welded steel structure, especially the restraint of the fillet joint. With the increase of the preheating temperature, the incidence of cracks decreases.
