Abstract

PURPOSE:To reduce the influence of heat input, and to make easy the nondestructive inspection for the weld zone, by installing a rectangular backing metal on one side of outer circumference constructive parts of box-type section being divided into two parts, for the purpose of forming the welding groove, and then, by carrying out the buttering welding before the electroslag welding. CONSTITUTION:Three of four outer circumference constructive parts 1 1... of the box-type sectioned structural member A are welded so as to form a U-type section, after a ranging the internal stiffener 2 with the steel backing metal 6 respectively in the specified location. In the meantime, a rectangular backing metal 7, which hits the backing metal 6 of the stiffener 2 and forms the welding groove, is attached to remained one outer circumference constructive parts 1; and then, two parts are buttering welded 8. Next, the backing metal 6 is fitted to the rectangular backing metal 7 so as to form the box-type section; and the previously formed box-type starting tab 4 is attached to the electroslag welding portion where the rectangular groove 9 is previously formed. Under these conditions, the electroslag welding 10, according to the conventional method, is carried out so as to joint the stiffener 2 and the buttering weld zone 8.
