Nickel Welding Rod Guide to Products and Procedures

Nickel welding rods are a type of filler metal that contains nickel and other elements, such as chromium and molybdenum. They are used for welding high-temperature applications.

Nickel welding rods can be classified into different types, including 80/20 nickel and 60/40 nickel. The 80/20 nickel type contains 80% nickel and 20% chromium.

Nickel welding rods are available in various diameters, ranging from 0.035 inches to 0.125 inches. The diameter of the rod depends on the specific application and the desired weld penetration.

Nickel welding rods are used for welding a variety of materials, including steel, stainless steel, and nickel alloys. They are particularly useful for welding high-temperature equipment and components.

If you're new to nickel welding rod, it's essential to follow some basic procedures to achieve the best results.

To start, use AC or DC reverse polarity to ensure a strong weld.

Pre-heating heavy castings to 350°F minimum can be beneficial, especially when using NickelRod 55 on large parts.

Direct the arc on deposited metal with the electrode at a slight angle in the direction of travel for a smooth weld.

When using NickelRod 99, use a short arc and stringer beads, then skip or back-step weld and peen to relieve stresses.

Cool the casting slowly with either rod to prevent warping or cracking.

Here's a quick summary of the key differences between NickelRod 55 and NickelRod 99:
