には、ろう付ｉＪ後の検査工数が多大となっていた。However, in the method of joining by brazing, it is difficult to check whether the parts are reliably brazed just by looking at them. Furthermore, it is even more difficult to visually inspect whether sealing performance is achieved. Therefore, in the case of parts that require high sealing performance, such as eye joints, the number of man-hours required for inspection after brazing is large.
本発明はこのような事情に鑑みてなされたものであり、
目玉継手のうちｌ」工部とパイプ部とをろう付けなしに
