| 部分溶込み溶接継手の強度に関する研究 Experimental Studies on the Strength of Welded Joints with Partial Penetration 鷲尾 健三(Kenzo Washio) 滝沢 章三(Shozo Takizawa) |
| 要旨 : 本研究は，部分溶込み溶接の継手強度に関し，従来より不明確なまま残されていた問題点を明らかにし，設計指針を得ることを意図した実験的研究である。実験は，溶込み量，および補強すみ肉のサイズを要因にして行なった。その結果，それぞれの要因が，継手強度にかなりの影響を与えることを示し，既往の研究と比較しつつ，継手強度を求める実験式を与えた。さらに，部分溶込み溶接は，すみ肉溶接より高強度が期待でき，かつ，有用な溶接であることを確めた。 |
| Synopsis : Lately, the partially-penetrated welding method has received considerable attention. But little information has been available about the strength of welded joints using this method. This paper is intended for clarifying some problems which have remained uncertain, and for suggesting a possible design method. The experiments were conducted on two variable factors amount of penetration and size of fillet welding for reinforcement. The results show clearly that these factors had remarkable effect upon the strength of joints, and the experimental formula has been given by comparing the test-results with the past studies. Generally speaking, it may be concluded from our investigations that the welded joints with partial penetration are stronger than the fillet welded joints and also that the partially penetrated welding is a useful method. |
