Abstract:

The objective of this program is to study the effect of different types of welding procedures, particularly preheating, thermal stress relieving, and mechanical stress relieving, on the susceptibility of wide plate specimens to brittle failure. The aim is to obtain quantitative data in terms of both temperature and load carrying ability as related to the improvement in such characteristics resulting from the preheating and various other methods of stress relief over the aswelded conditions. In order to achieve the desired objectives and in order to answer some of the questions that have been raised with regard to the behavior of notched tensile specimens, a series of preliminary tests was undertaken involving longitudinally welded flat plate specimens having different types of prepared notches oriented perpendicular to the butt-weld joining the two halves of the plate. Six basic types of notches were investigated in the preliminary program. Author
