Welding Rod Sizes and Uses-How to Select Rods for Welding

It is essential to know your tools before learning or working. And welding working is not easy, and you should have proper knowledge before perform any welding. If you are planning to practice stick welding, then you have to know about welding rods sizes and uses.

Today in this article, we are going to talk about various sizes of welding rods and their uses. Knows welding rods is not enough because you have to know which rods are consumable and which rods are non-consumable. If you stay with me until the end of this article and read carefully, then I will explain every about the stick welding rods and where and what welding rod size to use.

The most common rods professional welders use is 6010, 6011, 6012, 6013, 7018, and 7028. You can also find the different sizes of rods, and they all have different usage at welding projects. And you have to careful because welding rod selection is essential to get satisfying welding results.

Classification of welding rods

If you are a beginner in the welding world, then you probably do not know about the rods classification and welding rod numbers. The numbers on the welding rods provide information about the rods, and the welders easily can understand their usages.

The welding rods makers industries refer these numbers in three sets. The first two numbers are for rods tensile strength and the third number represents that from which positions you can use the rod. And the last number gives information about which coatings are used on the rods.

Like if the rod’s first two numbers are 70, then it means the welding rod can withstand 70,000 pounds per square inch. The third number is 1 in the most case because you can use that rod in all four positions. And as I said, the last number represents the coated, and it also helps you to choose the correct, current flow.

Let’s have a quick look at the rod classification chart.
