MILD STEEL & IRON POWDER ELECTRODES
KOBE ELECTRODE RB-26
For welding of steel sheets and light structures
Classifications:
JIS Z3211 D4313
AWS A5.1 E6013
Applications
Shielded metal arc welding of steel sheet structures in ships, railway vehicles and cars made of mild steel.
Characteristics on Usage
RB-26 is a high titania type covered electrode which makes it possible to do vertical downwards welding with the diameters up to
5.0mm.
The arc is stable with little spatter and the 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
penetration.
Notes on Usage:
(1) In the case of vertical downward welding, manipulate the electrode keeping its tip in contact with mother plate as shown in
the sketch.
(2) Pay attention not to exceed the range of proper currents. Welding with excessive current not only lowers X-ray soundness, but
also causes increase of spatter, undercut and insufficient slag covering.
(3) Dry the electrodes at 70-100oC for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in
some porosities.
