Comparison of Advanced High Strength Steel Thick Plate Joined by Hybrid Plasma Arc Welding and GMAW
In this paper, the applicability of the hybrid plasma arc welding (HPAW) on advanced high strength steels was studied. As a comparison, gas metal arc welding (GMAW) experiments were also conducted on the same materials. Compared with GMAW, the HPAW have the advantages not only in the welding efficiency, but also in the mechincal properties, as well as in the post-weld deformation. Microhardness test showed that HPAW specimens have higher hardness. Moreover, according to the microstructure shot by scanning electron microscope, compared with GMAW, the lath martensite in welding joint with HPAW is more.
