WELDALLOY S
Electrodes for Welding Mild Steel with Least Distortion and Operator Fatigue.
WELDALLOY S has a smooth, uniform deposits. Excellent for all position welding. Due to flared arc, the distortion is reduced to minimum and so also burn through in thin sheets.
Clean weld areas from grease, dirt and rust. Use
low current and short arc. Avoid weaving to reduce distortion.
Tensile Strength (Typical) : 48 Kgf/mm2
Elongation (Typical) : 28%
Autobodies, chassis, steel doors and windows, steel furniture, storage tanks, pipelines, machinery guards
and sheet metal works. Also suitable for structural
fabrication.

WELDALLOY LH
Controlled Hydrogen Type Electrode for Joining and Overlaying Medium Carbon, High Tensile, Cast & Other Problematic Steels.
WELDALLOY LH is a high deposition efficiency welding electrode, giving dense and crack free deposit, which has excellent X-ray quality. Due to
higher strength and ductility of deposit
toughness is high giving excellent impact resistance at ambient and sub-embient
temperature.
Clean area to be welded. For good results, dry electrodes at 2500C. Preheating may prove beneficial for repairs of oil or grease soacked
components or welding heavy sections in cast
steels.
Tensile Strength (Typical) : 55-60 Kgf/mm2
Elongation (Typical) : 30%
Autobodies, chassis, steel doors and windows, steel
furniture, storage tanks, pipelines, machinery guards
and sheet metal works. Also suitable for structural
fabrication.
