Effect of different active materials on WAAM depth of penetration and weld morphology

The Gas Metal Arc welding process was used to prepare single-track and multilayer samples. effects of CaF2 TiO2 on the penetration width depth samples are studied. results show that addition these two active agents will reduce surface morphology quality single-track, but it deepen single-track. Compared with sample CaF2, can maintain a better single track while increasing penetration. ratio effective melting maximum is close without adding.
