Dynamic Tear Test Correlation with Explosion Bulge Test at the Same Temperature

Abstract

As investigation entitled Toughness Evaluation of Electrogas and Electroslag Weldment" was completed in March 1975 by ABS under the welding research project SP 1-3, sponsored by MARAD and ABS. In this investigation the properties of welds in ordinary and higher strength hull structure steels made with electrogas (EG) and electroslag (ES) high heat input mechanized welding processes were compared with those from the metal arc (MMA) and submerged arc welding (SAW) processes with toward extending the applicability of the high input processes shipbuilding. Comparisons were made primarily with respect to manual a view in toughness as evaluated by explosion bulge, Charpy V-notch, dynamic tear and drop weight tests. The investigation which was exploratory in nature provided several general conclusions relative to the applicability of the high heat input (EG and ES) welding processes to the ordinary and higher strength hull steels. (See Ref. 1). In addition, it indicated several areas of work which were logical follow-on projects to help develop the technology to extend use of the high heat input EG and ES welding processes to shipbuilding. This report covers the results of DT tests for the. various grades of steel which were conducted at the same temperature as the explosion bulge tests.
