Effect of Acicular Ferrite on Crack ing Sensibility in the

The base metals were Q550 steel produced by thermo mechanical controlled rolling process and Q690 quenched-tempered steel. The suffix numbers 690 and 550 which denoted minimum yield strengths were 690 MPa and 550 MPa, respectively. Three strength match welding wires of 1.2 mm in diameter (ER50-6 wire, MK·G60 wire and Effect of Acicular Ferrite on Cracking Sensibility in the Jul 15, 2011 · High strength steels Q690+Q550 were welded using three different welding wires without preheating by gas shielded arc welding process. Microstructural characteristics of weld metals and nucleation mechanism of acicular ferrite were investigated by means of scanning electron microscope (SEM), energy dispersive spectrum (EDS) and transmission electron microscope (TEM).
