Properties of submerged arc welded TMCP-steel weldments
- Helsinki Univ. of Technology, Espoo (Finland). Lab. of Engineering Materials
In this investigation weldability, mechanical properties and effects of different heat inputs and welding consumables on the properties of weldments of the thermomechanically control processed (TMCP) steel, RAEX 500M were examined. The hardness measurements and transverse tensile tests showed that HAZ softening was insignificant in the TMCP-steel weldments studied. The weld metal strength properties were equal to or higher than those of the base metal through the heat input range of 2.0 to 6.0 kJ/mm. The required low temperature impact toughness of 40 J was achieved with plate thickness of 40 mm at {minus}60 C with all the filler materials used except with S2Ni2 (welding energy 5.8 kJ/mm) and S2Ni2 with metal powder addition (welding energy 5.9 kJ/mm). With high welding energies and longer cooling times (t{sub 8/5}) favorable weld metal microstructures were achieved with Mo-, Ti- and B-alloyed filler materials.
