DESCRIPTION AND APPLICATIONS:

RAJCORD-13 S is a medium heavy coated, all position rutile type electrode for major structural work where finish is of importance. The electrode produce a smooth, clean deposit with very little spatter loss and the slag is easy to remove. Electrodes are easy to operate in all positions and best suited for vertical upward and overhead welding. Ideal for radiographic quality on tubes and pipes of boilers. Lower gauges excellent for sheet metal work.

RAJCORD-13 S is suitable for structural, pressure vessels, boilers, pipelines, railway wagon and coaches, ships, barges, bridges, storage tanks, automobile bodies, LPG Cylinders, Steel furniture etc.
