Welding rod sizes

What are the different types of welding rods? The welding rod is the piece of wire connected to the welding machine. A current is fed through this wire, which helps to join two pieces of metal together firmly. In certain cases – namely SMAW and stick welders – the wires actually melt, becoming part of the weld itself. These welding rods are referred to as consumable electrodes.

Mild steel and low alloy steel stick electrodes.

The mild steel and low alloy steel stick electrodes include the following varieties. It is suitable for welding steels in vertical or overhead applications. Arc welding electrodes are identified using the A. The E stands for arc welding electrode. Note that these ratings can be different between various electrode manufactures for the same size rod.

Re: What size welding rod would be best to use? Basic Stick Welding Electrode Selection. A good example of what the strength of a weld is the rod numbers themselves.

As seen from the table above, you can tell what diameter of a welding rod you can use and the metal thickness you can use it on, for best.

Note that the thicker the material to be welded is, the higher the current neede and the larger the electrode needed. The thicker the rod , the higher your amperage rating has to be. Below are pictures of the above stated rod types. As a general rule of thumb, TIGDCEN, while Stick WeldingDCEP. Although stick welding is primarily used on carbon steel, you can purchase rods to weld some stainless steels and aluminum.

The most common rod for stainless steel is 30 which works for base metals that are classified as either 3or 3using the AISI standard. Stainless steels, incidentally, are classified using three-digit numbers, falling mostly in the 20 3and 4range. In turn, the rod diameter you use depends on the thickness of the steel you are welding.

Tweak and change as necessary for your own situation. TIG Welding Parametres Table. The rod size to plate suggestions are often for maximum speed and efficiency. ELECTRODE IDENTIFICATION. The “E” stands for arc welding electrode.

Choose the type of welding rod based on the material to be welde taking into consideration the diameter, electrical conductivity and possibly the tensile strength that is stamped on the electrode. This video is meant to help you understand the different types of. Figure 1: Example Wire Gauge Sizes In the metric system, welding cable size is typically expressed in square millimeters (mm2), representing the cross-sectional area of the cable. It refers to the thickness of the core wire. Roughly the electrode will weld steel of its thickness or a bit less to about twice its thickness.

You can also build welds up with multiple passes with a thin rod.

Stick electrodes from Lincoln Electric are designed for mild and low alloy steel welding applications. Is there a rule of thumb when selecting the size of filler wire to use. What determines the size of the filler wire.
