Description:
MT-48 is Iow hydrogen type electrodes containing iron powder for
ordinary Iow alloy steel. As the covering contains iron powder, it welds
with high efficiency, the melting rate is around 110%. It operates in all
positions on DC and AC(AC open circuit voltage≥70V). The deposited
metal has high plasticity, better toughness and crack resistance.
Applications:
For welding key structures and 50 kg/mm2class high tensile steel of ships and bridges.
