RIGIDITY REINFORCEMENT PLATE AND METHOD OF PRODUCING RIGIDITY REINFORCEMENT PLATE

摘要

A rigidity reinforcement plate formed by welding one or more rigidity reinforcement members (20) to a surface of a steel plate (10). A V- or J-shaped groove (24) is formed at an edge (22) of a rigidity reinforcement member in contact with the steel plate, a root (26) of the V- or J-shaped groove is subjected to laser welding, and a beveled section (28) is subjected to arc welding.
