The Weldability of Modern Structural TMCP Steels

抄録

The basic principles of the thermomechanical control process (TMCP) are recalled. The chemical compositions, mechanical properties and weldability of TMCP structural steels, especially those with a yield strength between 355 and 500 MPa, are reviewed with a special attention given to the work produced by IIW Commission IX: "Behaviour of metals subjected to welding."
