Introduction to Nimonic
Nickel and chromium are the main components of NIMONIC alloys. These alloys are well-known for their high performance and low creep at high temperatures. Aluminum, carbon, and titanium are infused into the alloy as additives. The NIMONIC alloy was created in England in 1940. NIMONIC 75, NIMONIC 80A, 81, 86, NIMONIC PE11, and 16 are commercially available NIMONIC alloys.
What is a Welding Rod?
When performing shielded metal arc welding, a welding rod is a generic term for electrodes or filler metal used to join two other base metals.
Welding rods can be either consumable or non-consumable depending on their application. The bonding material that holds two metal pieces together is formed when consumable rods disintegrate or melt. Non-consumable rods, on the other hand, simply provide enough catalytic reaction with the base metals to propagate fusing in an oxygen-rich atmosphere. Any continuous weld bead’s length is directly proportional to the welding rod’s length.
This article will assist you in distinguishing between different types of welding electrodes and will provide you with a good understanding of their strengths and weaknesses so that you can make the best choice for your welding needs.
Stick, MIG, and flux-cored arc welding all require consumable electrodes. Stick electrodes are the consumable electrodes used in stick welding. Heavy-coated electrodes, shielded arc electrodes, and light-coated electrodes are among them.
Non-consumable electrodes are easier to comprehend than consumable electrodes, not only because they do not melt, but also because there are only a few of them.

What do the Numbers Mean on a Welding Rod?
Even though we’ve already covered the two most common types of welding rods, you might still be confused about which one is best for your needs. This is because your welding rod will almost certainly have multiple numbers written on it. These can be very confusing for those who are new to welding machines and their accessories. Thankfully, these figures are available to assist you in selecting the best welding rod for your needs.
What is the Most Common Welding Rod Size?
Before purchasing a welding rod, you should consider its size rating in addition to the type of welding rod you intend to use with your welding machine. This measurement simply indicates the diameter of the welding rods you’re using. The majority of welding rods available range from 1/8 inch to 5/32 inch in diameter. Those of you who are purchasing a welding rod of similar size should be fine as long as it is the correct type.
