<p>PROBLEM TO BE SOLVED: To allow positioning to be performed whenever before welding in order to enable welding at normal temperature.SOLUTION: A combining method of metal members is provided in which a steel plate 2 is embedded into a concave portion 3 of a steel plate 1 with three sides being faced mutually, and facing parts 1a and 2a, facing parts 1b and 2b, and facing parts 1c and 2c thereof are combined. A positioning jig 4 is arranged on radial lines (a) to (e) extending in the radial directions from the center of the steel plate 2. The steel plate 1 and the steel plate 2 are combined by the positioning jig 4. The steel plate 2 is positioned with relative movement being enabled only along the direction of the radial lines to the steel plate 1. After the temperature of the steel plate 1 and the steel plate 2 becomes at normal temperature, the facing parts 1a and 2a, the facing parts 1b and 2b, and the facing parts 1c and 2c are combined temporally, and the actual combination is carried out after the temporary combination.</p> |
