There are many types of electrodes in TOKO brand. But one of the most popular electrodes for beginners is the E6013. As you can see, electrodes are defined and characterized by four numbers. The very first two numbers “60” stand for its tensile strength which means the E6013’s tensile strength is up to 59,700 pounds per inch or almost 60,000 pounds per inch and its yield strength is 67,700 psi. The third number of “1“, however, indicates that you can use these welding electrodes in all four positions of vertical, horizontal, flat, and overhead.

The last number “3” refers to the type of slag, flux composition, and power supply used for this electrode. The last digit indicates explicitly the following: if it is 0, it means DCRP. If it is 1, it means you can use either DC or AC Reverse Polarity. If it is 2, it means you can use DC or AC straight polarity. If it is 3, it means you can use DC or AC straight or reverse polarity.

Uses and Applications of 6013 Rod

The E6013 is designed for medium to light penetration welding. It is used for welding carbon steel and is also used for welding any type of polarity. As mentioned above, it is very popular for beginners because it readily provides a stable arc that is fit for welding poor fitting joints. It is also used for welding mild steels, some low allow steels, and galvanized steels. Its characteristic spray-type arc is very forceful and results in deep penetrations. 

Moreover, you can easily remove the slag that it produces. The typical applications of the E6013 include welding sheet metals, vehicles, ship repair and building, and welding of overworked and overly worn-out mild steel surfaces. It can also be used in general and light fabrications. You can use this rod for filling on multi-pass welds wherein you need to put on layer after layer to create a weld. The E6013 can also provide quality weld even though it produces shallow penetration by simply bonding with the metal that lays underneath it.  The E6013 is often preferred by beginners due to its excellent arc stability, making it suitable for weak fitting joints. Moreover, it leaves a smooth, pleasant-looking finish which, along with its arc stability, makes it convenient when working with uneven or short welds requiring positional adjustment. It is suitable for work on carbon steel and can be used for welding with any polarity.

E6013 Frequently used for:

-Welding of vehicles

-Shipbuilding and repair

-Excessively machined and damaged mild steel

-Thin sheet metal welding

-Other general light fabrication

Characteristics of E6013

E6013 is usually described as the “beginner’s rod, “sheet metal rod,” or even “easy rod.” These appendages to the E6013 may be indicative of its benefits. But you can also view these appendages negatively. 

Although western people are distrustful of the E6013, it is however very popular among Europeans and Asians, especially, for purposes of doing a root pass welds. Moreover, Asians and Europeans seem to make the E6013 their choice when it comes to root pass.

The E6013 appears to have its merit for it leaves behind a smooth inside root. After a bit of trial and error, you would surely discover that the E6013 can be easily kept from overly reinforcing the root. 

E6013 is characterized by easy flow nature, and this characteristic appears to work against it in the case of root pass. Contrariwise, however, it is not always the case, for this characteristic lets and prods the welder to move a bit quicker. Moreover, its backside slag formation in its weld is brighter and cleaner, indicative of less oxidation. This is surely a desirable quality when doing a root pass weld, especially, in pressurized situations.
