Stick electrodes are available in a wide range of types, each of which provides different mechanical properties and operates with a specific type of welding power source. There are several factors to consider in welding rod selection:. Before you power up your machine and pick up your electrode holder, learn more about each of these factors. The first step in choosing an electrode is to determine your base metal composition. Your goal is to match or closely match the electrode composition to the base metal type, which will help ensure a strong weld.

Welders Universe. And since scores of product lines exist, along with a variety of classification systems, ordering these items can be something of an adventure. Regardless, several important variables will factor into your selection process:. Following these standards should insure selecting the right product to meet the welding code. While manufacturers produce their own proprietary brands and models of products, they nonetheless bear the identification of the appropriate industry classification. So always be on the lookout for this info when shopping around. Due to the multitude of choices out there, an experienced welder, technician, purchaser or welding engineer maintains a binder or database containing the current product lines from different manufacturers and suppliers.

We have lots more on the site to show you. You've only seen one page. Check out this post which is one of the most popular of all time.

Different Types of Welding Rods and Their Uses

Whether your welding machine is electric or portable, the power source will provide either alternating current or direct current to the electrode. Alternating current flows in both directions, creating an amperage lag. Certain welding rods have been designed with stabilizers in the flux to help maintain the arc through these lags. Direct current welding machines provide a steady current in one direction. The direction of flow, called polarity, is determined by how the leads are connected to the welding machine.

Differences of Stick Welding (7018 vs 6013)

SMAW or stick electrodes are consumable, meaning they become part of the weld, while TIG electrodes are non-consumable as they do not melt and become part of the weld, requiring the use of a welding rod. Electrode selection is critical to ease of cleanup, weld strength, bead quality and for minimizing any spatter. Electrodes need to be stored in a moisture-free environment and carefully removed from any package follow the directions to avoid damage.

There is much more to know about electrodes apart from the material used to make them or whether they are consumable or non-consumable. Before I write about the different types of rods , you need to know the general meaning of these numbers so that you can have a smooth sail in understanding them. The first two numbers on the size number of the electrode usually represent the tensile strength of the electrode. The number 1 stands for all position, 2 for flat and horizontal position, and 4 stands for overhead, vertical, horizontal, and flat electrode positions. Digits on the last number denote the coating that has been used and consequently the current that you can safely use.
