Abstract

In this research was studied the weldability of Q&T armor steel MIL A46100 (Fe; 0.28%C; 0.30%Cr; 0.24%Mo y 0.2%Ni), with AWS E11018M filler metal and SMAW manual process, through relations generated between of microstructure, process variables, mechanical properties (tension, toughness impact Charpy V and microhardness); in addition was evaluated the susceptibility of the HIC through CTS (Controlled Thermal Severity) test and H plates on the weldments and the performance of service (ballistic performance), in different input heats, named: high and low. Has been established the incidence of the input heat on the properties and the service performance.
