Simply put; the resulting weld bead can withstand 60, pounds of force required to pull it apart. The third value represents the number of positions that the welding electrode can be used. Keep in mind that there are four primary welding positions: flat, horizontal, vertical and overhead. As an example, 1 means the rod can be used in all positions whereas 2 means it can only be used in flat or horizontal positions.
The last digit shows the coating type and kind of welding current alternating current, direct current or both , which can be used with the rod. The electrodes are quite popular. Taking this into account, E electrodes are mainly used in pipe welding and applications such as shipyards, water towers, steel castings, field construction and steel storage tanks.
Important to note though is that they can only run on welding equipment that use direct current DC. All You Need To Know. Furthermore, they have an extremely tight arc- an aspect that makes them difficult to handle, especially for amateur welders.
A distinguishing characteristic of the electrode is that it can be used on either alternating or direct current. This offers massive convenience as you can easily shift from one type of current to another to determine what works best. As mentioned earlier, this type of welding rod can withstand 60, psi of force without breaking. And like the electrode, the also delivers a deep penetration.
This makes it the best choice of electrode when you need to weld thicker materials. This also explains why the electrodes are used for welding applications that involve painted, dirty and greasy surfaces. A drawback of this electrode is that since it generates flat weld beads, it leaves ripples and somewhat rough finishes.
The is a general purpose welding rod that boasts superb bridging characteristics, particularly in application with sub-par fit-up. This electrode is also known to provide a good stable arc and it runs at high currents with minimal spatter.
That said, electrodes have two major limitations. Secondly, they generate thick waste material from smelting; hence, they require additional post-welding clean-up. Typical applications of this type of welding rod include connecting open joints, welding repair works, non-critical welding and the welding of rusted carbon steel sheets.
This is another popular electrode that generates a soft arc with little splatter. The is often used for moderate penetration welding and it has a readily removable slag. Taking these attributes into account, this type of electrode is used in instances that involve short or irregular welding tasks. Such uses include welding sheet metals, ship repair and building, and welding overworked or worn-out mild steel surfaces.
As we explained earlier, this electrode is designed to produce a much stronger weld that can withstand up to 70, psi. This compound is what vaporizes, and in the process, protects the weld bead from contamination by moisture and air.
This welding electrode can be used with both AC and DC power sources and in all four positions. Due to these characteristics, the has proven useful in structural welding. By this we mean the type of welding required in powerhouses, energy power plants, factories and bridges.
The main characteristic of this welding rod is its high content of iron powder. This is a crucial feature that significantly increases the deposition rate, and as a result, makes welding easier.
Also, rods are typically used for high-speed flat or horizontal welds. The and Welding rods are perfect for beginners. The left hardly to no slag. VERY easy to strike, but needed the right balance of bonding the pieces and burning through. If you are interested in the or welding rods then just follow the link to Amazon where you can see current pricing. The numerical classification system of electrodes may seem confusing at first, but once you understand what the numbers stand for, shopping for electrons will be a breeze.
The system, developed by the AWS, indicates how much pressure the rod can withstand, the correct position to weld, the composition of the flux, and the right current to use with the rod.
The most common rods in welding are , , , , and Using a rod as an example, you can determine the tensile strength of the rod by the first two numbers.
The numbers represent the pounds per square inch psi that the resulting weld can withstand. The third number of the electrode denotes its optimal position for welding. Only 1,2 and 4 are used. The number 1 means the electrodes can be used in all positions , the 2 signifies a flat, horizontal position, and 4 represents the overhead position or vertically up or down position.
In the case of the rod , this means that the rod can be operated in all positions. The last number represents the flux material and the appropriate current to use. The 8 signifies that the rod is composed of low hydrogen potassium and iron powder.
Electrode manufacturers include detailed specifications on the package that should answer all of your questions. Before you start a welding project, check the specifications before you set up your welding machine.
Most instructions also include which metals are suitable for the electrode and how to set the amperage on your machine. There are a few things you know when you purchase electrodes. Electrodes are fragile components and must be handled with care. Rods that are not structurally intact when you use them will not produce viable welds. The flux protects your weld pool and is essential in performing sturdy welds.
Rods are packaged in an airtight container when you purchase them and begin to degrade if you keep them unprotected for more than a few hours.
When you select an electrode for welding, remember to keep the remaining rods in a sealed container. The flux will turn to a soggy mess if it absorbs too much hydrogen or oxygen. Electrodes Expiry. Here are a few other factors you should consider:. Before you continue reading, here is an article we wrote about selecting a welding rod for cast iron. One thing you should take into account is the composition of the base metal.
Your primary goal here is to find a welding rod that closely matches the base metal. Doing so increases the chances of forming a strong and stable weld. Are you working with a broken section of a metal or a component? Determining whether the material is magnetic or nonmagnetic is another to distinguish the base metal. The cardinal rule here is that the more the flare in its sparks, the higher the carbon content of the base metal. When struck against a soft metal such as aluminum, a chisel leaves some sort of bite marks.
