Shielded metal arc welding of steel sheet structures in ships, railway vehicles and care made of mild steel.
Characteristics on usage:
KOBE-30is a high titania type covered electrode which makes it possible to do vertical downward 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 is 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
