The fabrication of the box-shaped steel structures is the key to the construction of the main building for the large-capacity converter at SISG.. The main difficulties with the fabrication are the high manufacturing quality required, the sophisticated shape of the structure encountered, and a strict control of the welding distortion needed. The fabrication method of the boxed shaped structure for the tower building, for example, is particularly described, in which the dimension precision of the entire structure is ensured by strictly controlling its assembling precision and welding distortion. A successful experience is thus gathered which can serve as a guideline to the fabrication of other large-sized box-shaped steel structures.
