How do you identify electrodes?

How do you identify electrodes?

Arc welding electrodes are identified using the A.W.S, (American Welding Society) numbering system and are made in sizes from 1/16 to 5/16 . An example would be a welding rod identified as an 1/8″ E6011 electrode. The “E” stands for arc welding electrode.

What are the different types of electrode?

There are two types of electrodes, cathodes, and anodes. Cathode attracts the positively charged cations. Anode attracts negatively charged anions. Electrodes are commonly made of metals such as platinum and zinc.

What are 2 different types of electrode sizes?

Common electrodes used in Stick welding are 6010, 6011, 6013, 7018 and 7024 with the most common diameters ranging from 1/8- to 5/32-in.

What does the electrode symbol code mean?

The letter “E” indicates an electrode. The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi). For example, the number 70 in a E7018 electrode indicates that the electrode will produce a weld bead with a minimum tensile strength of 70,000 psi.

What does the 1 in E7018 stand for?

Answered 4 years ago. E7018 electrode is used for SMAW. The E states for electrode. ’70’ tells that the the tensile strength of the resulted weld is 70000 psi. ‘1’ means that the electrode can be used in all welding positions (horizontal, vertical, flat and overhead).

What does the 3 in E6013 stand for?

What’s the best all around welding rod?


What does the 8 stand for in E7018?

For E7018 welding rods, the “8” is indicative of low-hydrogen flux mixed with potassium and iron powder compounds. The number “8” likewise indicates its medium penetration quality. Moreover, this number also denotes that this electrode works on reverse polarity DC current, DCEP and AC.

What are 6013 rods good?

The 6013 has a more mild penetration with a larger pool that doesn’t cut through rust like the 6010 or 6011. This electrode is a favorite for structural welders based on its smooth arc. Its mild penetration and bigger pool leave larger, stronger, less defined beads.

Is 6013 a drag rod?

“6013 is an AC-capable rod, but if I were to use it DC, I’d go electrode negative for the extra penetration, since 6013 is not a deep-penetration rod in AC mode.”

Do you drag 6013?

7024 is a common drag rod but is very liquidy and used for flat and very limited horizontal welding. 7018 is even more common and that rod can be dragged with great weld quality in flat (1F) Horz.

How many amps does a 6013?

6013 Welding Rod Amperage Chart

Electrode Diameter (Inches) Amperage Range
6013 1/16″ 20-45
6013 5/64″ 35-60
6013 3/32″ 40-90
6013 1/8″ 80-130

What is the polarity of 6013?

As a result, 6013 is an all-purpose electrode that provides a soft, steady arc that is easily regenerated, easy slag control for vertical-down welding, low spatter and a beautiful bead appearance. 6013 electrodes may be used in any position with AC or DC (straight or reverse polarity).

How do I know what amp to weld at?

The specific amperage to be used depends primarily on the diameter of the electrode. For example, an eighth in diameter electrode welds great between 75 and 125 amps. Whereas a 5/32 diameter electrode can weld optimally at up to 220 amps.

How many amps is a 1/16 Rod?

If using a 7018 rod of 3/32-inch diameter, the amperage should be around 50 amps on 1/16-inch thick steel and around 90 amps for 1/8-inch steel. For a 1/8-inch rod, try starting with 90 amps on 1/8-inch steel and around 140 amps on ¼-inch steel.

Is 7018 DCEP or DCEN?

7018 DCEP current can make it easier to control the arc and gain a more appealing weld bead because the direction of the current flow is constant. You can run it in DCEN but again that’s not made for penetration and in fact 7018 in DCEN is really for thin sheet metal.

What are 1/16 welding rods used for?

It is ideal for welding through light to medium amounts of dirt, rust or paint. The strong arc force makes this electrode perfect for rusty steel.

What polarity is used for 7018?

Is 6013 reverse polarity?

Polarity & Settings The 6013 electrodes can be used with AC or DC (either straight or reverse polarity) in any position.

Which is better AC or DC welder?

A smoother welding output than with AC. A more stable arc. Less spatter. DC negative offers faster deposition rates when welding thin sheet metals.

Is electrode positive or negative?

The part of the welding circuit that is positive (attracts electrons in the arc) is the anode. The part of the welding circuit that is negative (produces electrons in the arc) is the cathode. A useful mnemonic for this is PANiC (Positive Anode, Negative Cathode).

Is 6011 electrode positive or negative?

6011 runs on AC and direct current electrode positive (DCEP), while 6010 runs only on DCEP. This gives 6011 an advantage if you have an AC-only machine.

What is the term for a positive electrode?

The positively charged electrode in electrolysis is called the anode .

Which electrode is best for overhead position welding?

7018 electrode

What is the hardest welding position?

H-L045 / 6G Uphill and J-L045 / 6G Downhill: The hardest positions for a welder to perform. Usually only performed on weld tests, in order to qualify a welder for all other positions. This is essentially the same as PH / PJ / 5G but with the pipe at a 45º angle.

What is G in welding?

It involves welding on the top side of the joint. In this position, the molten metal is drawn downward into the joint. The result is a faster and easier weld. In 1G and 1F, the number 1 refers to the flat position, while the letter G stands for a groove weld and letter F stands for a fillet weld.

What head pattern is best for overhead welds?

Sticking it to vertical up overhead smaw. This is a good technique to use when you are in the vertical welding position or the overhead welding position. Bead welding is best for the overhead arc welding position.
