This is a high titania type of welding electrode
for mild steel. It is widely used for welding
sheets of ships, rolling stocks and automobiles,
for ornamental surfacing of thick plates.
Characteristics on usage
RB-26 is a high titania type covered electrode which makes it possible to do vertical
downward welding with diameters up to 5.0mm.
The arc is stable with little spatter and lustrous bead can be obtained.
RB-26 is most suitable for welding the structures, which need vertical downward welding in
particular while it is suitable for welding steel sheets and light structures because of shallow
Notes on usage
· In the case of vertical downward welding, manipulate the electrode keeping its tip in
contact with mother plate as shown in the sketch.
· Pay attention not to exceed the range of proper currents. Welding with excessive
current not only lower X-ray soundness, but also causes increase of spatter,
undercut and insufficient slag covering.
· Dry the electrodes at 70-100° C for 30-60 minutes before use. Excessive moisture
absorption lower usability and may result in some porosities.
