WELDED JOINT STRUCTURE AND WELD QUALITY DETECTION METHOD |
摘要 |
A joint structure by welding includes a butted part between facing surfaces of a first member and a second member and two-stepped clearances adjacent to the butted part, and a weld bead that is melted from a joint of the butted part which is positioned on an opposite side of the two-stepped clearances into the two-stepped clearances is formed in the butted part by welding. Other parts than the butted part are spaced apart from each other between the facing surfaces, and when a width of the weld bead is assumed to be "A", a width of a first level clearance of the two-stepped clearances that is adjacent to the butted part is assumed to be "B", and a width of a second level clearance of the two-stepped clearances that is adjacent to the first level clearance is assumed to be "C", the relation of "B < A/2 < C" is determined. |
