Abstract

SSe presentan aleaciones de soldadura adecuados para unir aceros de alta resistencia y baja aleacion. Estas aleaciones de soldadura tienen microestructuras de ferrita acicular intercalada en martensita; límites elásticos de al menos aproximadamente 690 Mpa (100 ksi), y DTTTs menores de aproximadamente û50 degree C (-58 degree F) medidas por una curva de energía de Charpy con entalla en V frente a la temperatura. Estos metales de soldadura incluyen aproximadamente 0,04% en peso aproximadamente 0,08% en peso de carbono, aproximadamente 1,0% en peso a aproximadamente 2,0% en peso de manganeso, aproximadamente 0,2% en peso a aproximadamente 0,7% en peso de silicio, aproximadamente 0,3% en peso a aproximadamente 0,8% en peso de molibdeno, aproximadamente 2,3% en peso a aproximadamente 3,5% en peso de níquel, aproximadamente 0,0175% en peso a aproximadamente 0,0400% en peso de oxígeno, y al menos un aditivo seleccionado a partir del grupo formado por (i) hasta aproximadamente 0,04% en peso de circonio, y (ii) hasta aproximadamente 0,02% en peso de titanio, siendo el resto Fe.
