RAJWELD – LH 8
RAJWELD – LH 8
(Basic Coated Low Hydrogen Type Electrode)
DESCRIPTION AND APPLICATIONS: A basic coated, low –hydrogen electrode for tough and crack free weld deposit, which is ductile and of radiographic quality. The all position electrode is best suited for welding rigidly resistance structures under heavy stresses condition. Ideal for welding medium and low alloy steels, heavy structures and difficult to weld steels where high ductility is required.
TYPICAL APPLICATIONS: Pressure vessels, penstock, boiler, ship building, blast furnace, atomic reactor shell and pipe work, heavy structures subject to dynamic loading etc.
Precautions:
- Store in a dry place.
- Redry the electrodes at 250°C for one hour before use and place the baked electrodes in carrying oven at 90oC while in use.
- Maintain appropriate current and short arc.
- Remove oil, grease, dust & rust from parent metal.
- Do not handle the electrodes with moisture greasy hand.
