HIGH ENERGY-DENSITY BEAM-WELDED PRODUCT, HIGH ENERGY-DENSITY BEAM-WELDING METHOD, WELDING METHOD, AND WELDING SUPPORTING DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a high energy-density beam-welded product, a high energy-density beam-welding method, a welding method, and a welding supporting device favorable for enhancing the reliability of the strength of a weld solidified part. PSOLUTION: The welded products is constituted by joining a plurality of plates 1, 2 attached to each other by a weld solidified part formed by high energy-density beams. The weld solidified part is exposed outwardly. The plurality of plates 1, 2 are put together, and abutting wall bodies 3, 4 are abutted on at least one side of the plurality of put-together plates 1, 2. Next, a molten portion is formed by irradiation with high energy-density beams, and the molten portions is solidified while retained by the abutting wall bodies 3, 4 to form the weld solidified part.
