Microstructural Characterization of HSLA-100 GMA-Weldments

Abstract

A high strength low alloy steel, HSLA-100, is under development by the U.S. Navy. Instead of developing a new weld filler metal for this alloy it is desirable to use the already certified filler metals that are used for welding HY-100 steel. The research presented in this thesis evaluated the effect of cooling rate on the HY-100 welding consumable when used to weld HSLA-100 plate. The 800 C to 500 C cooling rate after gas metal arc welding was varied from 22 C/sec to 42 C/sec by using different plate thickness, different preheat and interpass temperatures as well as different heat inputs. Mechanical property data is reported elsewhere but summarized in this thesis.
