This paper shows a study of the effect of the water depth on the microstructure and mechanical properties in joining structural steel welded in a marine environment in steels with a maximum CE (carbon equivalent) of 0.37%. Wet welding coupons of steel ASTM A36 were joined by the manual metal arc welding (MMAW) process at depths of 10, 20, 30, and 40m, using AWS Broco SoftTouch as filler metal (3.17mm diameter) inside a simulation hyperbaric chamber. Image analysis was applied to welded coupons, with the aim to obtain the phase quantification and porosity as well as mechanical properties.Theresultsshowthatthereisaninverserelationshipbetweentheincrease indepthat whichtheweldingis performedandthe mechanicalproperties,whilethe fillermetalpropertieswerekeptconstant.Microstructuralchangesvaryasafunction of the depth at which repair-maintenanceis performed,with an increase in growing phase shift which is highly undesirablebecause of their brittleness and hardness. | |
