| Abstract | ||
| The aim of the present research is to evaluate the best welded joints of types (V, VV, U,UU) and comparing them with the base metal type (ST-52-3) which is used in awide range at industry and then to show the effect of these types on the fatigue limit under the reverse bending loads effect. The results of the experimental tests for these four types of the welded joints show that the fatigue strength of the welded specimens is very nearly to the fatigue strength of the base metal and more precisely and that the difference between these welded joints and the base metal is (3.7 %, 4.2 %,4.5 %, and 5 % ) and by quality(better) arrangement will be (U,V,VV, and UU) respectively. | ||
