Welding and properties of welds of TMCP-steel
- Helsinki Univ. of Technology, Espoo (Finland). Lab. of Engineering Materials
Thermomechanical control process (TMCP) of steel includes a multiplicity of processing schedules of combined thermal and mechanical working treatments that have been developed to optimize the resulting microstructure and mechanical properties of various steel grades. Weld metal properties of multipass submerged arc welded (SAW) TMCP steel joints were investigated in order to study the influences of different welding wires and heat inputs. Weld metal characterization consisted of tensile, Charpy-V Notch (CVN) and hardness testing, and microstructural examination. Cross-weld tensile specimens were tested principally to examine whether HAZ softening, which might have occurred, causes failure in this region. The tests verified that by using the right welding wire; it is possible to achieve weld joint which fulfills the strength requirements and gives satisfactory toughness at low temperatures.
