Title :   Effects of Periods of Rest on the Fatigue Strength of Welded Joints.

Descriptive Note : Rept. no. 1.


Report Date : JAN 1941

Pagination or Media Count : 7

Abstract : The tests in this January 1941 report were conducted on a steel slightly softer than the standard grade for bridges and buildings (such as ASTM-A7). The Committee interprets the results of these tests to indicate that rest periods have no significant effect upon the fatigue strength of welded joints in such a steel, when these joints are made and tested under conditions approximating those met in general structural work; and this conclusion may be extended to welded joints in steel of the standard grade for bridges and buildings.
