Abstract
It was developed a welding condition for AISI304 stainless steel sheets with an AWS E316LT1-4 tubular wire using constant voltage source (CV) and pulsed arc. It was analyzed the influence of the welding parameters on the mechanical properties, such as tensile strength and Vickers microhardness. Based on the optimized condition, the influence of the heat input (H) in the tensile strength and microhardness profiles of the molten zone and heat affected zone was evaluated. Due to the results obtained, the best welding parameters adjustment condition was established, and the optimized condition provided the highest tensile strength. Microhardness analyzes profiles did not show considerable variations, when submitted to different levels of heat input. However, there were gains related to the ease of deposition through the control of the heat input, especially if these parameters are resized for the welding out of position; as well as to the increase of deposition rate, because for the same heat input, is necessary higher speeds wire.
