Applications

• Welding nickel-chromium-molybdenum alloys (e.g., Alloy 59, Inconel 625)
• Dissimilar metal welding (e.g., nickel alloys to steels)
• Cladding steel with Ni-Cr-Mo weld metal for improved corrosion resistance
• Applications in chemical processing plants, pollution control equipment, pulp and paper mills, etc.

Storage and Handling:

• Store in dry, cool conditions away from moisture and contaminants.
• Maintain electrodes in sealed containers until use.
• Follow recommended preheat and interpass temperatures for optimal welding results.

Safety Precautions

• Wear appropriate personal protective equipment (PPE) including welding helmet, gloves, and clothing.
• Ensure proper ventilation to avoid inhaling welding fumes.
• Handle electrodes carefully to prevent burns or injuries.
• Follow safe welding practices to avoid electrical hazards and fire risks.
