Effects of High Heat Input Welding of Construction Steels A36, A514, and A516.

Abstract

This report documents the results of a study of shielded metal-arc (SMAW) and gas metal-arc welding (GMAW) butt weld tests using high heat inputs of 60 to 90 kJ/in. (2362 to 3543 J/mm). The steels used in this study were American Society for Testing and Materials (ASTM) Specifications A36, A514, and A516. Plate thicknesses were 3/4 to 1 in. (19 to 25mm). It was concluded that strength levels were generally reduced by the higher heat inputs, but impact properties were not affected. A table of recommended heat inputs for the steels and electrodes investigated during this study is given. (Author)
